Description

  The present invention relates to a flying object that obtains lift using the Coanda effect.

  The Internet site (Non-Patent Document 1) shows a flying object that obtains lift using the Coanda effect.

Moreover, the flying document which obtains lift using compressed air is shown by the conventional literature (patent document 1). In this conventional document, a flying body that generates lift on an auxiliary wing using the Coanda effect is shown as an example.
http://jlnlabs.imars.com/gfsuav/n01amvt.htm JP-A-1-301495

  However, although the lift generator of the prior art generates lift using the Coanda effect of the fluid, the flow velocity decreases due to fluid loss, and therefore the lift decreases accordingly.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a flying object capable of increasing the lift due to the Coanda effect.

  In order to achieve the above-described object, a flying object according to the present invention has a fluid supply part that supplies fluid and an outer surface that is inclined downward with respect to the fluid flow direction, and changes the fluid flow direction downward. A lift generating unit that obtains lift and an opposing surface that opposes the outer surface of the lift generating unit, and the distance between the outer surface on the upstream side in the fluid flow direction and the opposing surface is the outer surface on the downstream side in the fluid flow direction. And a fluid collecting section wider than the distance between the opposite surfaces.

  According to the flying object described above, when the fluid supply unit supplies the fluid to the lift generation unit, the outer surface of the lift generation unit is inclined downward with respect to the flow direction of the fluid. It changes downward and lift acts on the lift generation part by the Coanda effect. On the other hand, the fluid collecting unit has a facing surface that faces the outer surface of the lift generating unit, and the distance between the facing surface and the outer surface of the lifting force generating unit is wider toward the upstream side. For this reason, when the fluid from the fluid supply unit passes between the lift generation unit and the fluid collection unit, the gas around the fluid inlet side of the fluid collection unit is drawn between the lift generation unit and the fluid collection unit. Pass through. As a result, it is possible to efficiently increase the lift acting on the lift generation unit.

  In the above-described flying object, it is preferable to further include an adjustment mechanism for adjusting the position or posture of the facing surface of the fluid collection unit. According to this configuration, since the posture of the opposing surface of the fluid collection unit is adjusted by the adjustment mechanism, the amount of fluid drawn between the lift generation unit and the fluid collection unit is adjusted, and the lift acting on the lift generation unit Can be adjusted.

  In the above-described flying object, the fluid supply section preferably has a fluid outlet, and the outlet is preferably disposed between the outer surface and the opposing surface. According to this configuration, since the fluid outlet of the fluid supply unit is disposed between the outer surface of the lift generation unit and the opposing surface of the fluid collection unit, the fluid is interposed between the lift generation unit and the fluid collection unit. Since the fluid loss at the time of passing becomes small, the fall of the lift which acts on a lift production | generation part can be suppressed.

  In the flying object described above, it is preferable that turbulent flow generation means for turbulent fluid flow is provided on the outer surface of the lift generation unit. According to this configuration, since the fluid flow is turbulent by the turbulent flow generating means provided on the outer surface of the lift generating unit, the fluid flowing along the outer surface of the lift generating unit is difficult to peel off from the outer surface. Lift can be reliably applied to the lift generator.

  In addition, what is necessary is just to comprise the flying body mentioned above so that the area of the opposing surface of a fluid collection part may become smaller than the area of the outer surface of a lift production | generation part. Moreover, what is necessary is just to comprise the flying body mentioned above so that the opposing surface of a fluid collection part may oppose the site | part upstream from the downstream edge part of the outer surface of a lift production | generation part. Moreover, what is necessary is just to comprise the flying body mentioned above so that the outer surface of a lift production | generation part may become the outer surface of the airframe main body of a flying body.

  In the above-described flying object, it is preferable to further include an internal energy increasing unit that increases the internal energy of the fluid upstream of the fluid collecting unit. According to this configuration, the internal energy increasing unit increases the internal energy of the fluid upstream of the fluid collecting unit. Since the internal energy of the fluid increases, the fluid expands more adiabatically near the fluid collection portion. Therefore, the momentum of the fluid flowing along the lift generation unit can be increased, and a large lift can be generated by the lift generation unit.

  In the flying object described above, it is preferable that the fluid collecting unit is configured using a heat insulating material. According to this configuration, since the fluid collecting unit is configured by using the heat insulating material, the internal energy of the fluid is less likely to be taken away by the fluid collecting unit, and the fluid is more adiabatically expanded near the fluid collecting unit. Therefore, the momentum of the fluid flowing along the lift generation unit can be increased, and a large lift can be generated by the lift generation unit.

  In the above-described flying object, a plurality of fluid collecting units are provided along the fluid flow direction, and one of the fluid collecting units is more than the distance between the outer surface and the opposing surface at the downstream end of any one of the plurality of fluid collecting units. It is preferable that the distance between the outer surface and the opposed surface at the upstream end of the fluid collecting portion on the downstream side is larger. According to this configuration, since a plurality of fluid collecting units are provided along the fluid flow direction, a large amount of fluid can be collected by the plurality of fluid collecting units and flow along the lift generating unit. A large lift can be generated by the generator.

  In the above-described flying object, at least one of the plurality of stages of fluid collecting units is located at either the first position facing the outer surface of the lift generating unit or the second position stored inside the lift generating unit. It is preferably configured to be adjustable. According to this configuration, when the fluid collection unit is moved to the first position facing the outer surface of the lift generation unit, the fluid collection unit contributes to the improvement of lift. On the other hand, when the fluid collection unit is moved to the second position stored in the lift generation unit, the fluid collection unit does not contribute to improvement of lift. That is, the lift force acting on the flying object can be adjusted by adjusting the position of at least one of the fluid collecting portions to either the first position or the second position.

  In the above-described flying object, it is preferable to further include a water vapor supply device that supplies water vapor to the fluid passing through the fluid collecting unit. According to this configuration, since the water vapor is supplied to the fluid passing through the fluid collecting unit, the aggregation latent heat is given to the fluid when the water vapor is aggregated. As a result, since the internal energy of the fluid increases, the fluid expands more adiabatically near the fluid collecting portion. Therefore, the momentum of the fluid flowing along the lift generation unit can be increased, and a large lift can be generated by the lift generation unit. Note that the fluid supply unit may supply fluid using a non-combustion drive mechanism.

  ADVANTAGE OF THE INVENTION According to this invention, the flying body which can enlarge the lift by a Coanda effect can be provided.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description, the same reference numerals are used for the same elements or elements having the same function, and redundant description is omitted.

[First Embodiment]
First, the flying object 1 according to the first embodiment of the present invention will be described. FIG. 1A is a schematic cross-sectional view of the flying object 1 according to the first embodiment as viewed from the side. FIG.1 (b) is the top view which looked at the flying body 1 which concerns on 1st Embodiment from upper direction, and the II cross section of FIG.1 (b) respond | corresponds to Fig.1 (a).

  The flying object 1 according to the first embodiment is configured in a disk shape as a whole, and is an object that obtains lift using the Coanda effect and flies. The flying object 1 according to the first embodiment includes a lift generation unit 10, a fluid supply unit 20, and a fluid collection unit 30.

  The fluid supply unit 20 is disposed at the upper center of the disk-shaped lift generation unit 10. The fluid supply unit 20 has a mechanism for generating a fluid flow, such as a fan, a jet engine, or a propeller, inside, and fluid (air) is discharged from an outlet 22 formed on the side surface to the upper outer surface of the lift generation unit 10. 12 is supplied. The outlets 22 of the fluid supply unit 20 are formed in all directions of 360 ° as viewed from above, and supply fluid to the upper outer surface 12 of the lift generation unit 10 in all directions of 360 °.

  The lift generation unit 10 is the airframe body of the flying object 1. The lift generation unit 10 is generally formed in a disc shape, and has a circular shape when viewed from above and a shape extending in the lateral direction when viewed from the side. The upper outer surface 12 of the lift generating unit 10 is a curved surface that protrudes upward. For this reason, in each part of the upper outer surface 12 of the lift generating unit 10, the upper outer surface 12 of the lift generating unit 10 is inclined downward with respect to the fluid flow direction. The upper outer surface 12 of the lift generation unit 10 has a curved surface with a small curvature near the center, and the lift obtained at this portion is small. On the other hand, the upper outer surface 12 of the lift generating unit 10 has a maximum curvature of the curved surface at a portion 12a away from the center, and the lift obtained in the vicinity of this portion is large.

  The fluid collection unit 30 is a ring-shaped plate member disposed above the lift generation unit 10. The lower surface of the fluid collection unit 30 is a facing surface 32 that faces the upper outer surface 12 of the lift generation unit 10. The facing surface 32 of the fluid collecting unit 30 is a curved surface that protrudes downward. The distance between the opposing surface 32 of the fluid collecting unit 30 and the upper outer surface 12 of the lift generating unit 10 is wide on the upstream side in the fluid flow direction and narrow on the downstream side in the fluid flow direction. The area of the opposed surface 32 of the fluid collecting unit 30 is smaller than the area of the upper outer surface 12 of the lift generating unit 10. The facing surface 32 of the fluid collecting unit 30 faces a portion upstream of the downstream end of the upper outer surface 12 of the lift generating unit 10, and more specifically, the upper surface 12 of the lift generating unit 10. It faces the upstream portion of the maximum curvature portion 12a.

  According to the flying object 1 of the present embodiment described above, when the fluid supply unit 20 generates a fluid flow and supplies the fluid flow to the lift generation unit 10, the upper outer surface 12 of the lift generation unit 10 is downward with respect to the fluid flow direction. Therefore, the fluid flows along the upper outer surface 12 of the lift generation unit 10, and the fluid flow direction changes downward on the upper outer surface 12. At this time, lift acts on the lift generation unit 10 due to a change in the direction of the flow due to the Coanda effect, causing the flying object 1 to rise against gravity. In addition, the lift according to the curvature of the part acts on each part of the upper outer surface 12 of the lift generation part 10. In the vicinity of the maximum curvature portion 12a of the upper outer surface 12 of the lift generation unit 10, the lift is maximized.

  The fluid collecting unit 30 has a facing surface 32 that faces the upper outer surface 12 of the lift generating unit 10, and the distance between the outer surface and the facing surface on the upstream side in the fluid flow direction is the downstream side in the fluid flow direction. It is wider than the distance between the outer surface and the opposing surface. For this reason, when the fluid from the fluid supply unit 20 passes between the lift generation unit 10 and the fluid collection unit 30, the surrounding gas on the fluid inlet side of the fluid collection unit 30 becomes the lift generation unit 10 and the fluid collection unit. Passed between 30. Such a fluid phenomenon is called an eject effect (ejector effect).

  Here, the relationship between the fluid flow velocity and the loss will be described. When the fluid is relatively slow, the influence of the viscosity is dominant in the fluid resistance and is proportional to the first power of the velocity. Therefore, there is little decrease in the momentum of the fluid, fluid separation is suppressed, and fluid loss is small. . On the other hand, when the fluid is relatively fast, the fluid resistance is dominated by the inertia due to the influence of inertia and proportional to the square of the velocity. Decrease, fluid separation is large, and fluid loss is large.

  In the above-described flying object 1, since the gas around the fluid inlet side of the fluid collection unit 30 is drawn between the lift generation unit 10 and the fluid collection unit 30, the flow rate of the fluid is increased and the flow rate of the fluid is decreased. Can do. In this way, by making the fluid flowing along the upper outer surface 12 of the lift generating unit 10 at a low speed and a large flow rate, it is possible to suppress the momentum of the fluid from significantly decreasing due to the resistance of the surrounding fluid. As a result, the lift acting on the lift generation unit 10 can be increased.

  In addition, the flying object 1 mentioned above has the advantage that a flight state is stabilized compared with a normal helicopter. That is, when the attitude of the flying object 1 is tilted during the flight, the fluid pressure at the portion increased by the inclination of the lift generation unit 10 becomes higher than the fluid pressure at the portion decreased by the inclination of the lift generation unit 10. Attempt to return body 1 to its original position. Therefore, the flying object 1 can return to the original horizontal state even when the posture is lost from the horizontal state, and is strong against disturbances when stationary or when the direction is changed.

[Second Embodiment]
Next, the flying object 3 according to the second embodiment of the present invention will be described. FIG. 2A is a schematic cross-sectional view of the flying object 3 according to the second embodiment as viewed from the side. FIG. 2B is a top view of the flying object 3 according to the second embodiment as viewed from above, and a II-II cross section in FIG. 2B corresponds to FIG.

  As in the first embodiment, the flying object 3 according to the second embodiment is configured in a disk shape as a whole, and is an object that obtains lift using the Coanda effect and flies. The flying body 3 according to the second embodiment includes an adjustment mechanism 40 for adjusting the position or posture of the fluid collection unit 30 in addition to the lift generation unit 10, the fluid supply unit 20, and the fluid collection unit 30. The fluid collection unit 30 includes eight plate members 34 that are independent of each other, and is arranged in a ring shape as a whole. An adjustment mechanism 40 is provided corresponding to each plate member 34.

  The adjustment mechanism 40 that adjusts the position or posture of the fluid collection unit 30 includes a first adjustment mechanism 43, a second adjustment mechanism 42, and a third adjustment mechanism 41. The first adjustment mechanism 43 includes an actuator that drives the plate member 34 in the fluid flow direction, and adjusts the distance from the fluid supply unit 20 of the facing surface 32 of the fluid collection unit 30. The second adjusting mechanism 42 includes an actuator that drives the plate member 34 in a direction perpendicular to the fluid flow direction, and adjusts the distance from the lift generating unit 10 of the facing surface 32 of the fluid collecting unit 30. The third adjustment mechanism 41 includes an actuator that rotationally drives the plate member 34, and adjusts the posture of the facing surface 32 of the fluid collection unit 30 with respect to the upper outer surface 12 of the lift generation unit 10. In other words, the third adjustment mechanism 41 adjusts the degree of opening of the plate member 34 facing the upstream side.

  A control device 44 for controlling each of the first adjustment mechanism 43, the second adjustment mechanism 42, and the third adjustment mechanism 41 is provided inside the flying body 3. In addition, the flying object 3 includes the flying state of the flying object 3 (the ground speed of the aircraft, the relative velocity of the aircraft with respect to the air, the angle of the aircraft with respect to the traveling direction, the temperature of the aircraft, the angle of the aircraft with respect to the direction of gravity, the fluid supply amount, A plurality of types of sensors (not shown) for detecting fluid temperature, etc.) are provided. The control device 44 takes in the detection value from the sensor, calculates a drive command corresponding to the flying state of the flying object 3, and supplies this drive command to each adjustment mechanism 40. Each adjusting mechanism 40 adjusts the position and posture of the fluid collection unit 30 according to the drive command. Thus, when the control device 44 controls each adjustment mechanism 40, an appropriate lifting force can be obtained according to the flying state of the flying object 3.

[Third Embodiment]
Next, the flying object 5 according to the third embodiment of the present invention will be described. FIG. 3A is a schematic cross-sectional view of the flying object 5 according to the third embodiment as viewed from the side. FIG.3 (b) is the top view which looked at the flying body 5 which concerns on 3rd Embodiment from upper direction, and the III-III cross section of FIG.3 (b) respond | corresponds to Fig.3 (a).

  As in the first embodiment, the flying object 5 according to the third embodiment is configured in a disk shape as a whole, and is an object that obtains lift using the Coanda effect and flies. The flying body 5 according to the third embodiment includes a lift generation unit 10, a fluid supply unit 20, and a fluid collection unit 30, and the fluid outlet 22 of the fluid collection unit 30 is connected to the upper outer surface 12 of the lift generation unit 10 and the fluid. It arrange | positions between the opposing surfaces 32 of the collection part 30. FIG.

  In the present embodiment, since the fluid outlet 22 of the fluid collecting unit 30 is disposed between the upper outer surface 12 of the lift generating unit 10 and the opposing surface 32 of the fluid collecting unit 30, most of the fluid is fluid outlet. After being blown out from 22, it passes between the upper outer surface 12 of the lift generation unit 10 and the facing surface 32 of the fluid collection unit 30 without being blocked by the fluid collection unit 30. Therefore, the fluid loss by the fluid collecting unit 30 can be suppressed, and the lift acting on the lift generating unit 10 can be increased.

[Fourth Embodiment]
Next, the flying object 7 according to the fourth embodiment of the present invention will be described. FIG. 4A is a schematic cross-sectional view of the flying object 7 according to the fourth embodiment as viewed from the side. FIG. 4B is a top view of the flying object 7 according to the fourth embodiment as viewed from above, and the IV-IV cross section in FIG. 4B corresponds to FIG.

  As in the first embodiment, the flying body 7 according to the fourth embodiment is configured in a disk shape as a whole, and is an object that obtains lift using the Coanda effect and flies. The flying body 7 according to the fourth embodiment includes a lift generation unit 10, a fluid supply unit 20, and a fluid collection unit 30, and turbulent flow that turbulently flows the fluid on the upper outer surface 12 of the lift generation unit 10. Generation means 50 is provided.

  The turbulent flow generating means is a plurality of convex portions 50 for generating turbulent flow fixed to the upper outer surface 12 of the lift generating unit 10. The turbulent flow generation convex portion 50 is formed by forming a wire made of a metal into a circular shape and joining it to the upper outer surface 12 of the lift generation portion 10. The convex portion 50 for generating turbulent flow is fixed on the outer side of the portion of the upper outer surface 12 of the lift generating unit 10 that faces the fluid collecting unit 30. The turbulent flow generating projections 50 are fixed to the upper outer surface 12 of the lift generating unit 10 with an interval in the fluid flow direction. The turbulent flow generating projection 50 is a minute object as compared with the lift generating unit 10, and generates a turbulent flow only in the inner layer of the fluid flowing along the upper outer surface 12 of the lift generating unit 10. As described above, the generation of the turbulent flow makes it difficult for the fluid to be separated from the upper outer surface 12 of the lift generating unit 10, and the fluid easily flows along the upper outer surface 12 of the lift generating unit 10. Therefore, the lift from the upper outer surface 12 of the fluid lift generation unit 10 is suppressed, and a larger amount of fluid is caused to flow along the upper outer surface 12 of the lift generation unit 10, so that the lift due to the Coanda effect can be obtained more reliably. Can do.

  In the present embodiment, the turbulent flow generating means is the minute convex portion 50, but the turbulent flow generating means is not limited to this. For example, the turbulent flow generation means may be a recess formed in the upper outer surface 12 of the lift generation unit 10. Further, the flying object according to the present embodiment has a disk shape, but the present invention is not limited to this, and for example, the flying object including the fluid supply unit 20, the fluid collection unit 30, the wing 60, and the flap 62 as shown in FIG. The body 9 may be used.

[Principle of lift force generation]
The “flying body lift generation principle” common to all the embodiments described in this specification will be described in detail. FIG. 6 is a side view of the flying object 1 for explaining the lift generation principle of the flying object.

  According to the flying object 1 of the embodiment, when the fluid supply unit 20 generates a fluid flow and supplies the fluid flow to the lift generation unit 10, the fluid flows along the upper outer surface 12 of the lift generation unit 10. Since the upper outer surface 12 of the lift generation unit 10 is inclined downward with respect to the fluid flow direction, the fluid flow direction changes downward on the upper outer surface 12. Such a fluid phenomenon is called the Coanda effect. When the fluid flow direction changes due to the Coanda effect, the fluid momentum changes. That is, since the fluid flow direction changes downward, the downward component of the fluid momentum increases.

  At this time, as a reaction of the change in the fluid flow direction due to the Coanda effect, a lift acts on the lift generation unit 10 to lift the flying object 1 against gravity. The greater the downward component of the fluid momentum, the greater the lift acting on the lift generator 10. That is, the magnitude of the lift acting on the lift generation unit 10 is determined by factors such as the flow rate of the fluid flowing along the lift generation unit 10 and the curvature of each part of the upper outer surface 12 of the lift generation unit 10.

  The distance between the upstream end 32 u of the facing surface 32 of the fluid collecting unit 30 and the upper outer surface 12 of the lift generating unit 10 is the distance between the downstream end 32 d of the facing surface 32 of the fluid collecting unit 30 and the upper outer surface 12 of the lifting generating unit 10. Wider than. For this reason, when the fluid blown out from the outlet 22 of the fluid supply unit 20 passes between the lift generation unit 10 and the fluid collection unit 30, the fluid obliquely above the upstream side of the fluid collection unit 30 becomes the lift generation unit 10. It is drawn between the fluid collecting unit 30. Such a fluid phenomenon is called an eject effect (ejector effect). Due to this ejection effect, the surrounding fluid merges with the fluid blown out from the fluid supply unit 20, so that the mass of the fluid passing between the lift generation unit 10 and the fluid collection unit 30 increases (event 1).

  There are two fluid layers between the lift generator 10 and the fluid collector 30. One fluid layer is a fluid layer formed by the fluid blown out from the fluid supply unit 20 and is a fluid layer flowing on the lift generation unit 10 side. Another fluid layer is a fluid layer formed by a fluid drawn from the surroundings, and is a fluid layer flowing on the fluid collecting unit 30 side. Since the fluid layer on the lift generation unit 10 side is pressed against the lift generation unit 10 by the fluid layer on the fluid collection unit 30 side, it is difficult to separate from the lift generation unit 10.

  The fluid layer on the lift generation unit 10 side has a large flow velocity before entering between the lift generation unit 10 and the fluid collection unit 30, but gradually decelerates between the lift generation unit 10 and the fluid collection unit 30. . On the other hand, the fluid layer on the fluid collecting unit 30 side has a flow velocity of almost zero before entering between the lift generating unit 10 and the fluid collecting unit 30, but between the lift generating unit 10 and the fluid collecting unit 30. Is gradually accelerated. That is, the average flow velocity of the fluid flowing between the lift generation unit 10 and the fluid collection unit 30 is smaller than the average flow velocity of the fluid blown out from the fluid supply unit 20 (event 2).

  Between the lift generation unit 10 and the fluid collection unit 30, the fluid adiabatically expands. That is, between the lift generating unit 10 and the fluid collecting unit 30, the internal energy of the fluid itself is converted into external work for expanding the fluid, and thereby the fluid expands. As the fluid expands and the volume of the fluid increases, the fluid flow rate increases. Thus, the adiabatic expansion of the fluid between the lift generating unit 10 and the fluid collecting unit 30 contributes to increasing the flow velocity of the fluid (event 3).

  As described above, in the fluid collecting unit 30, the mass of the fluid increases due to the ejection effect, and the fluid flow velocity decreases as a whole (event 1 and event 2 described above). Further, the adiabatic expansion of the fluid contributes to increasing the fluid flow velocity (the above event 3). As a result, when the fluid before passing between the lift generation unit 10 and the fluid collection unit 30 is compared with the fluid after passing between the lift generation unit 10 and the fluid collection unit 30, the flow rate of the fluid is Increases overall. The increase in the flow rate of the fluid in this way is greatly affected by the adiabatic expansion of the fluid between the lift generation unit 10 and the fluid collection unit 30.

  Since the flow rate of the fluid increases in the fluid collecting unit 30, the change in the momentum of the fluid when the fluid flow direction changes due to the Coanda effect is large. Therefore, it is possible to increase the lift acting on the lift generation unit 10, which is the reaction of the change in the fluid flow direction. Here, since the adiabatic expansion of the fluid is performed using the internal energy of the fluid itself, it is not necessary to increase the energy consumption of the fluid supply unit 20 in order to increase the lift acting on the lift generation unit 10. In other words, by providing the flying body 1 with the fluid collection unit 30, an increase in lift acting on the lift generation unit 10 and an energy saving of the fluid supply unit 20 are realized.

  In addition, since the flow velocity of the fluid after merging is smaller than the flow velocity of the fluid from the fluid supply unit 20, the influence of the viscosity is dominant and the fluid resistance is proportional to the first power of the velocity. Fluid separation is also suppressed, and fluid loss is small. (Reference: Conversely, when the fluid is relatively fast, the fluid resistance is dominated by the influence of inertia and proportional to the square of the velocity. (Reduction is noticeably reduced, fluid separation is large, and fluid loss is large.)

  However, a decrease in the fluid flow rate is not essential in order to increase the lift acting on the lift generation unit 10. Depending on the structure of the lift generation unit 10 and the fluid collection unit 30, the flow rate of the fluid is reduced when the surrounding gas on the fluid inlet side of the fluid collection unit 30 is drawn between the lift generation unit 10 and the fluid collection unit 30. It is possible to increase the flow velocity of the fluid as it increases. As a result, the lift acting on the lift generation unit 10 can be increased. Therefore, the present invention does not exclude the case where the lift generation unit 10 and the fluid collection unit 30 are configured to increase the flow velocity of the fluid.

[Contrast with Japanese Patent Publication No. 63-60222]
Further, the effect of the flying object according to the embodiment will be described in comparison with the technique disclosed in the prior art (Japanese Patent Publication No. 63-60222). This conventional document shows a turbine engine for a V / STOL machine. This turbine engine is configured to introduce outside air into the exhaust passage through the secondary air introduction path using the eject effect.

  As one method for obtaining lift, there is a method in which a turbine engine is arranged vertically and a jet flow of the turbine engine is injected vertically downward. However, when the turbine engine is arranged vertically, the turbine engine does not have a curved surface that causes the Coanda effect unlike the flying object according to the embodiment of the present invention. For this reason, when the turbine engine is arranged vertically, the outside air introduced by the ejection effect only passes through the inside of the turbine engine, and does not give a reaction force to the turbine engine, but increases the lift force acting on the turbine engine. Does not contribute. That is, in order to obtain lift like the flying object according to the embodiment, it is important to obtain a synergistic effect by combining the fluid increase phenomenon due to the eject effect and the lift generation phenomenon due to the Coanda effect.

  As another method for obtaining lift, there is a method in which a turbine engine is disposed horizontally and a jet flow generated by the turbine engine is injected along a blade surface (curved downward curved surface) of the airframe. However, the jet flow ejected from the turbine engine is a swirling vortex that rotates and is not rectified and easily diffuses, and therefore does not flow along the wing surface of the fuselage. Therefore, when the turbine engine is disposed horizontally, the outside air introduced by the eject effect does not contribute to the lift acting on the airframe.

  Further, as shown in FIG. 2 of the above-mentioned conventional document, there is a method in which a turbine engine is horizontally arranged and a jet flow is deflected vertically downward by a deflector. The turbine engine of FIG. 2 is provided with a deflection flap that tilts downward, but this deflection flap does not contribute to lift generation. This is because the deflector and the deflection flap of the turbine engine constitute a bend pipe, and a secondary flow perpendicular to the pipe axis is generated in the vicinity of the deflection flap, so that fluid does not flow along the deflection flap.

  In the flying body according to the embodiment, the fluid flowing along the lift generation unit is unlikely to be separated from the upper surface of the lift generation unit, in contrast to the technology according to the conventional literature. For this reason, the flying object according to the embodiment can effectively obtain lift.

[Sixth Embodiment]
Next, the flying object 70 according to the sixth embodiment of the present invention will be described. FIG. 7 is a schematic top view of the flying object 70 according to the sixth embodiment as viewed from above. The flying body 70 according to the sixth embodiment is an airplane 70 having a fuselage 72 that is long in the front-rear direction and a pair of wing parts 80L and 80R that extend from the center of the fuselage 72 to the left and right. In the airplane 70, a fluid supply unit 90 and a fluid collection unit 100 are mounted on the wing portions 80L and 80R, and the wing portions 80L and 80R are lift generation units.

  FIG. 8 is a schematic cross-sectional view of the wing part 80 of the flying object 70 according to the sixth embodiment when viewed from the side, and a VIII-VIII cross section in FIG. 7 corresponds to FIG. The flying body 70 according to the sixth embodiment includes a lift generation unit 80, a fluid supply unit 90, and a fluid collection unit 100. Furthermore, the flying body 70 according to the sixth embodiment includes an internal energy increasing unit 110 for increasing the internal energy of the fluid as a part of the fluid supply unit 90.

  The fluid supply unit 90 is disposed on the front side of the wing upper surface 82 which is the lift generation unit 80. The fluid supply unit 90 includes a propeller 94 that is driven to rotate by using a drive mechanism 93 such as a motor or an internal combustion engine as a power source. The fluid supply unit 90 generates fluid (air) from an outlet 92 formed on a side surface of the propeller 94. 80 is supplied to the upper outer surface 82. In the modification of the present embodiment, the fluid supply unit 90 may include another type of mechanism that generates a fluid flow, such as a fan or a jet engine.

A partition plate 95 that separates the lower space _{RL in} which the propeller 94 is disposed from the upper space _RH that is the upper side of the propeller 94 is provided in the fluid supply unit 90. At the front end of the fluid supply unit 90, a suction port 96 for taking in fluid into the fluid supply unit 90 is formed. An outlet 92 for blowing out the fluid inside the fluid supply unit 90 is formed at the lower rear end of the fluid supply unit 90. When the propeller 94 is driven to rotate, the fluid in front of the fluid supply unit 90 is sucked into the fluid supply unit 90 from the suction port 96, passes through the lower space _RL of the fluid supply unit 90, and is blown out. Blow out from 92 to the rear of the fluid supply unit 90.

On the other hand, the configuration provided in relation to the upper space _RH of the fluid supply unit 90 is an internal energy increasing unit 110 that increases the internal energy of the fluid located obliquely above the upstream side of the fluid collecting unit 100. The internal energy increasing unit 110 of this embodiment is configured to warm the fluid upstream of the fluid collecting unit 100 using exhaust heat (exhaust) of a power source such as a motor or an internal combustion engine. Hereinafter, the configuration of the internal energy increasing unit 110 will be described.

Internal energy increasing portion 110 of the present embodiment, the exhaust heat supply pipe 97 is a tubular member for supplying the heated fluid by waste heat of the power source 93 to the upper space R _H is, the fluid supply from the power source 93 The portion 90 extends to the upper space _RH . In addition, an exhaust heat supply duct 98 that is a blower pipe extending from a corner portion at the upper rear end of the fluid supply unit 90 is provided at the upper rear end of the fluid supply unit 90. The exhaust heat supply duct 98 extends obliquely upward on the downstream side of the fluid supply unit 90 while bending in an arc shape. In other words, the position obliquely above the downstream side of the fluid supply unit 90 is the position obliquely above the upstream side of the fluid collection unit 100, and the fluid drawn between the fluid collection unit 100 and the lift generation unit 80 due to the eject effect. It is a passing position.

According to the configuration of the internal energy increasing portion 110 described above, heated fluid is supplied to the upper space R _H by the exhaust heat of the power source 93, with the fluid flowing into the upper space R _H from the suction port 96, exhaust heat It passes through the supply duct 98 and blows out obliquely upward on the downstream side of the fluid supply unit 90. In this way, the internal energy increasing unit 110 supplies heat to the fluid upstream of the fluid collecting unit 100 to increase the internal energy of the fluid. Therefore, the adiabatic expansion of the fluid in the vicinity of the fluid collecting unit 100 can be promoted, the momentum of the fluid flowing along the lift generating unit 80 can be increased, and the lift generating unit 80 can generate a large lift.

  Moreover, according to the structure of the internal energy increase part 110 mentioned above, since the big lift is generated by the lift production | generation part 80, the flying body 70 can be raised to a higher altitude. In addition, since the lift acting on the lift generation unit 80 is increased using the exhaust heat generated from the power source 93, the flying object 70 can be energy-saving.

  Further, as described above, since the internal energy is reduced due to the adiabatic expansion of the fluid and the temperature is lowered, water in the fluid tends to condense and the ice tends to adhere to the fluid collecting unit 100. On the other hand, according to the configuration of the internal energy increasing unit 110 described above, ice is attached to the fluid collecting unit 100 because the fluid upstream of the fluid collecting unit 100 is heated using the heat generated from the power source 93. Can be suppressed. Therefore, the fluid flowing along the fluid collecting unit 100 is prevented from being disturbed by the ice attached to the fluid collecting unit 100, and the lift generated in the lift generating unit 80 can be prevented from being lowered. .

  Note that the configuration of the internal energy increasing unit 110 in the present embodiment is merely an example. The configuration of the internal energy increasing unit 110 is not limited to the configuration of the present embodiment as long as the internal energy of the fluid passing between the fluid collecting unit 100 and the lift generating unit 80 is increased. (1) For example, in the present embodiment, the internal energy increasing unit 110 uses the exhaust heat of the power source 93. However, in the modified example of the present embodiment, the internal energy increasing unit 110 is provided separately from the power source 93. The fluid may be warmed by the heat of the generated heating element.

  (2) In the present embodiment, the internal energy increasing unit 110 warms the fluid drawn by the ejection effect. However, in the modification of the present embodiment, the internal energy increasing unit 110 warms the fluid blown from the outlet 92. It may be a thing. For example, a case where a jet engine is disposed inside the fluid collecting unit 100 and the fluid blown from the outlet 92 of the fluid collecting unit 100 is combustion gas of the jet engine is an example.

  (3) In the present embodiment, the internal energy increasing unit 110 warms the fluid before reaching the fluid collecting unit 100. However, in the modification of the present embodiment, the internal energy increasing unit 110 is a fluid collecting unit. The fluid passing between 100 and the lift generation unit 80 may be warmed. For example, as in the modification of the sixth embodiment shown in FIG. 9, the fluid collecting unit 100 may be provided with a heating element 105 to heat the fluid flowing along the fluid collecting unit 100. The heating element 105 is, for example, a heating wire that generates heat when a current flows, a steam pipe through which high-temperature steam flows, a heat pipe through which high-temperature liquid flows. Note that it is preferable to provide a heating element on the upper outer surface 82 of the lift generating unit 80 because the internal energy of the fluid can be increased.

  In the modification of the sixth embodiment, the facing surface 102 side of the fluid collecting unit 100 is made of a high-strength material such as steel, and the opposite side is made of a heat insulating material 106. According to this configuration, since the fluid collection unit 100 is configured using the heat insulating material 106, the internal energy of the fluid is hardly taken away by the fluid collection unit 100, and the heat of the heating element 105 escapes to the opposite side surface. Can be suppressed. Therefore, the fluid can be further adiabatically expanded in the vicinity of the fluid collection unit 100, and a large lift can be generated by the lift generation unit 80. In addition, you may comprise the opposing surface 102 side of the fluid collection part 100 with a heat insulating material. Also, it is preferable to provide a heat insulating material on the upper outer surface 82 of the lift generating unit 80 because the internal energy of the fluid can be increased.

  In the modification of the sixth embodiment, a vibrator 108 such as a piezo element is provided in the fluid collecting unit 100 in order to prevent the adhesion of ice. Since the vibrator 108 vibrates the surface of the fluid collecting unit 100 and shakes off the ice attached to the fluid collecting unit 100, it is possible to suppress disturbance of the fluid flowing along the facing surface 102 of the fluid collecting unit 100. The lift acting on the lift generating unit 80 can be increased. In addition, when the fluid is heated using the above-described heating element 105, the heat of the heating element 105 is not used for melting the ice by shaking off the ice adhering to the fluid collecting unit 100 in advance. Therefore, the lift force can be reliably increased by using the heat of the heating element 105. However, the heating element 105 may be used as a configuration for preventing the adhesion of ice.

  Further, in order to prevent the ice from adhering to the fluid collection unit 100, the fluid collection unit 100 and the lift generation unit 80 may be painted black so that the temperature rises when receiving sunlight.

[Seventh Embodiment]
Next, the flying object 70 according to the seventh embodiment of the present invention will be described. The flying object 70 according to the seventh embodiment is an airplane as in the sixth embodiment. FIG. 10 is a schematic cross-sectional view of the wing portion of the flying object 70 according to the seventh embodiment as viewed from the side.

  In the flying body 70 according to the seventh embodiment, each of the wings is provided with two fluid collecting units 100 and 120 along the fluid flow direction. The first-stage fluid collecting unit 100 on the upstream side is arranged at a constant distance from the fluid supply unit 90, and the second-stage fluid collecting unit 120 on the downstream side is further fixed from the first-stage fluid collecting unit 100. Arranged at a distance.

  The fluid collecting unit 100 in the first stage has a facing surface 102 that faces the upper outer surface 82 of the lift generating unit 80, and the distance between the upper outer surface 82 and the facing surface 102 at the upstream end in the fluid flow direction is as follows. It is wider than the distance between the upper outer surface 82 and the opposing surface 102 at the downstream end in the fluid flow direction. Therefore, when the fluid that blows out from the fluid supply unit 90 and flows along the lift generation unit 80 passes through the first-stage fluid collection unit 100, the fluid on the fluid inlet side of the fluid collection unit 100 generates lift due to the ejection effect. It is drawn between the part 80 and the fluid collecting part 100.

  The second-stage fluid collecting unit 120 has a facing surface 122 that faces the upper outer surface 82 of the lift generating unit 80, and the interval between the upper outer surface 82 and the facing surface 122 at the upstream end in the fluid flow direction is as follows. It is wider than the distance between the upper outer surface 82 and the opposing surface 122 at the downstream end in the fluid flow direction. The distance between the upper outer surface 82 and the opposing surface 122 at the upstream end of the second-stage fluid collecting unit 120 is larger than the distance between the upper outer surface 82 and the opposing surface 102 at the downstream end of the first-stage fluid collecting unit 100. It ’s wider. Therefore, when the fluid that blows out from the fluid supply unit 90 and flows along the lift generation unit 80 passes through the second-stage fluid collection unit 120, the gas on the fluid inlet side of the fluid collection unit 120 generates lift due to the ejection effect. It is drawn between the part 80 and the fluid collecting part 120.

  According to the flying object 70 of the present embodiment, by providing the two-stage fluid collecting units 100 and 120 along the upper outer surface 82 of the lift generating unit 80, compared to the case where the single fluid collecting unit 100 is provided. The flow rate of the fluid along the lift generation unit 80 can be increased. Therefore, the momentum of the fluid flowing along the lift generation unit 80 can be increased, and the lift generation unit 80 can generate a large lift. In the present embodiment, the two-stage fluid collecting units 100 and 120 are provided along the upper outer surface 82 of the lift generating unit 80. However, in the modification of the present embodiment, the upper outer surface 82 of the lift generating unit 80 is provided. Three or more stages of fluid collecting units may be provided along the line.

Further, the flying object 70 of the present embodiment is provided with a position adjusting mechanism 130 for adjusting the position of the fluid collecting unit 120 at the second stage. The position adjustment mechanism 130 moves and adjusts the position of the second-stage fluid collection unit 120 in accordance with a command from the control device 132. The fluid collecting unit 120 in the second stage has the basic position P ₁ facing the upper outer surface 82 of the lift generating unit 80 or the storage position P ₂ stored inside the lift generating unit 80 by the position adjusting mechanism 130. The position can be adjusted to either one.

According to this arrangement, when moving the fluid collector 120 of the second stage in the basic position P _1, since the flow rate of the fluid is increased by the fluid collector 120 of the second stage, the second stage of the fluid collection portion 120 contributes to the improvement of lift. On the other hand, when moving the second stage of the fluid collector 120 in the storage position P _2, the fluid collector 120 of the second stage does not contribute to the lift improvement. That is, by freely moving the fluid collector 120 of the second stage to one of the basic position P ₁ or the storage position P _2, it is possible to adjust the lift acting on the projectile 70.

The storage in the projectile 70 of the present embodiment, the second stage of the fluid collector 120 when hovering projectile 70 moves to the basic position P _1, a fluid collector 120 of the second stage when moving projectile 70 it is particularly preferred to move to a position P _2. Advantages of such a control method will be described below.

During hovering projectile 70, with moving the fluid collection portion 120 of the second stage in the basic position P _1, it is less than normal flow rate of the fluid discharged from the fluid supply unit 90. Even if the flow rate of the fluid blown out from the fluid supply unit 90 is small, the flow rate of the fluid is increased by the two fluid collecting units 100 and 120. Therefore, energy consumption in the fluid supply unit 90 can be suppressed, and a sufficient lift force can be obtained for the flying body 70 to hover.

  The flying speed of the flying object 70 has a characteristic that it cannot be made larger than the flow velocity of the fluid flowing along the lift generation unit 80. In the control method at the time of hovering described above, the flow velocity of the fluid flowing along the lift generation unit 80 is slowed by using the two fluid collection units 100 and 120, and therefore, it is necessary for the ascending movement and horizontal movement of the flying object 70. The flow rate may not be obtained. Therefore, the above-described control method during hovering is not suitable as a control method during movement of the flying object 70.

Accordingly, upon movement of the projectile 70 is configured to move the fluid collector 120 of the second stage in the storage position P _2, the flow rate of the fluid discharged from the fluid supply unit 90 and the normal. Since the second-stage fluid collecting unit 120 is stored and the second-stage fluid collecting unit 120 does not reduce the flow velocity of the fluid, the fluid flows along the lift generation unit 80 at a high speed. Therefore, a propulsive force large enough for the flying body 70 to move upward and horizontally can be obtained by the fluid flowing at high speed along the lift generation unit 80. That is, according to the flying object 70 of the present embodiment, by adjusting the position of the fluid collecting unit 120 at the second stage, energy saving of the flying object 70 at the time of hovering is realized, and the flying object 70 at the time of movement is arranged. Sufficient acceleration performance can be realized.

  In the present embodiment, the second-stage fluid collecting unit 120 is configured to be adjustable in position. However, in the modified example of the present embodiment, the first-stage fluid collecting unit 100 may be configured to be adjustable in position. Good. Further, when three or more fluid collection units are provided in the flying object 70, at least one of the plurality of fluid collection units may be configured to be adjustable in position. Further, when the plurality of fluid collecting units are configured to be adjustable in position, the control device performs control so as to move from the downstream fluid collecting unit to the storage position in accordance with the flying state of the flying object 70. Just do it.

  In addition, although the internal energy increase part 110 is provided in the flying body 70 of this embodiment similarly to the flying body 70 of 6th Embodiment, it is good also as a structure where the internal energy increase part 110 is not provided. Further, the flying object 70 of the present embodiment may be combined with the configuration of the other embodiments disclosed in the present specification.

[Eighth Embodiment]
Next, a flying object 70 according to an eighth embodiment of the present invention is described. The flying object 70 according to the eighth embodiment is an airplane as in the sixth embodiment. FIG. 11 is a schematic cross-sectional view of the wing portion of the flying object 70 according to the eighth embodiment when viewed from the side.

  In the flying body 70 according to the eighth embodiment, a water vapor supply device 140 that supplies fluid (air) containing water vapor to a plurality of positions of the wing portion is provided. The water vapor supply device 140 includes a reservoir 141 for storing water, a water vapor feeding pipe 142, a water vapor feeding pump 143, and a water vapor generating heater 144.

The water stored in the reservoir 141 is sucked up by the water vapor feed pump 143 and travels inside the water vapor feed pipe 142a. Water is heated by the steam generation heater 144 in the middle of the steam feed pipe 142a, and a wet fluid saturated with water vapor is generated. The fluid saturated with water vapor further travels inside the water vapor feeding pipe 142a and reaches the branch point. The pipe 142a for water vapor feeding includes a first pipe 142b extending to the upper space _RH of the fluid supply unit 90, a second pipe 142c extending to the lower space _RL of the fluid supply unit 90, and the fluid collecting unit 100. It branches off to a third pipe 142d extending to a position immediately before the upstream side.

A part of the fluid traveling inside the water vapor feeding pipe 142 a passes through the inside of the first pipe 142 b and is discharged into the upper space _RH of the fluid supply unit 90. The fluid containing the discharged water vapor blows out from the upper space _RH through the duct 98 and obliquely upward on the upstream side of the fluid collecting unit 100. The fluid blown out from the duct 98 is drawn between the fluid collection unit 100 and the lift generation unit 80.

In addition, the other part of the water vapor that travels inside the water vapor feeding pipe 142 a passes through the inside of the second pipe 142 c and is discharged into the lower space _RL of the fluid supply unit 90. Fluid containing the released water vapor, blown into the upstream side of the fluid collection unit 100 through the outlet 92 from the lower space R _L. The fluid blown out from the outlet 92 flows between the fluid collecting unit 100 and the lift generating unit 80.

  Further, the remaining part of the water vapor that travels inside the water vapor feeding pipe 142a passes through the inside of the third pipe 142d and is discharged to a position immediately before the fluid collecting unit 100. The steam flows between the fluid collecting unit 100 and the lift generating unit 80 together with the fluid flowing from the upstream side.

  When the fluid adiabatically expands in the vicinity of the fluid collecting unit 100, the water vapor contained in the fluid agglomerates if conditions such as air temperature and atmospheric pressure for aggregating the water vapor are met. At this time, since the phase is transformed from water vapor to ice or water, coagulation latent heat is given to the surrounding fluid. This agglomeration latent heat becomes internal energy of the fluid flowing between the fluid collecting unit 100 and the lift generating unit 80, and promotes adiabatic expansion of the fluid. Therefore, according to the steam supply device 140 of the present embodiment, the lift generating unit 80 can generate a large lift by increasing the flow rate of the fluid flowing along the lift generating unit 80. The volume of the fluid contracts slightly when the water vapor condenses, but the volume contraction rate is a negligible value and hardly affects the lift acting on the flying object 70.

  In the water vapor supply device 140 of the present embodiment, the amount of water vapor supplied may be changed according to the surrounding environment of the flying object 70. That is, the supply amount of water vapor may be increased when the humidity around the flying object 70 is low, and the supply amount of water vapor may be decreased when the humidity around the flying object 70 is high. By adjusting the supply amount of water vapor in this manner, the lift force acting on the flying object 70 is appropriately adjusted according to whether the zone in which the flying object 70 is flying is a dry zone or a wet zone. be able to.

  Further, the water vapor supply device 140 of the present embodiment is suitable when the power source 93 for driving the propeller is a non-combustion drive mechanism such as an electric motor. When the propeller is driven by a combustion type drive mechanism, exhaust gas containing water vapor is generated by combustion. Therefore, the exhaust gas is discharged to the upstream side of the fluid collection unit 100, thereby aggregating latent heat to the adiabatic expansion fluid. Can be given. On the other hand, when the propeller is driven by a non-combustion type drive mechanism, exhaust gas containing water vapor is not generated, so the fluid may be poor in water vapor. Therefore, it is preferable that the steam acting on the lift generating unit 80 can be increased by supplying the steam using the steam supply device 140 of the present embodiment.

  In the present embodiment, steam is generated using the electric heater 144, but the steam is generated using the exhaust heat of the power source 93 (engine, motor, inverter, fuel cell, etc.) instead of the electric heater 144. May be generated.

  Further, the flying body 70 of the present embodiment is provided with a water recovery device 150 for recovering the condensed water. The water recovery device 150 includes a recovery groove 151 for water recovery, a pipe 152 for returning water, and a pump 153 for returning water. The recovery groove 151 for water recovery is formed near the rear end of the upper outer surface 82 of the lift generation unit 80. A part of the water condensed when the fluid is adiabatically expanded adheres to the upper outer surface 82 of the lift generation unit 80, flows along the upper outer surface 82 of the lift generation unit 80, and enters the recovery groove 151. Then, the water that has entered the recovery groove 151 flows into the pipe 152a for returning water. When the water return pump 153 is driven, the water flowing into the water return pipe 152 c is returned to the reservoir 141.

  The water return pipe 152b extends to the lower surface of the fluid collection unit 100. The other part of the water condensed when the fluid is adiabatically expanded adheres to the facing surface 102 of the fluid collecting unit 100 and flows along the facing surface 102 of the fluid collecting unit 100 to return the water return pipe 152b. Flow into. When the water return pump 153 is driven, the water flowing into the water return pipe 152 c is returned to the reservoir 141. According to the water recovery apparatus 150 of the present embodiment, water (ice or water droplets) adhering to the upper outer surface 82 of the lift generation unit 80 and the fluid collection unit 100 can be recovered and reused.

  In order to avoid a situation where water runs out during the flight of the flying object 70, it is necessary to start the flying of the flying object 70 after storing sufficient water to be used during the flight in the reservoir 141. However, if the water recovery device 150 of the present embodiment is used, water is recovered and reused during flight, and therefore there is little fear of running out of water during the flight of the flying object 70, and a reservoir 141 having a small water storage capacity is used. Can do.

  In this embodiment, the water return pump 153 is driven to collect water in the reservoir 141. However, the water return pump 153 is not provided, and the water is returned to the reservoir 141 by the action of gravity. May be.

  In addition, although the internal energy increase part 110 is provided in the flying body 70 of this embodiment similarly to the flying body 70 of 6th Embodiment, it is good also as a structure where the internal energy increase part 110 is not provided. Further, the flying object 70 of the present embodiment may be combined with the configuration of the other embodiments disclosed in the present specification.

FIG. 12 is a schematic cross-sectional view of the wing portion of the flying object 70 according to the ninth embodiment as viewed from the side.

  In the flying body 70 according to the ninth embodiment, the outlet 92 of the fluid supply unit 90 is disposed between the upper outer surface 82 of the lift generation unit 80 and the facing surface 102 of the fluid collection unit 100. With this configuration, fluid loss in the fluid collection unit 100 can be suppressed, and the lift acting on the lift generation unit 80 can be increased.

  In the flying body 70 according to the ninth embodiment, the upper outer surface 82 of the lift generation unit 80 is provided with turbulent flow generation means 84 for turbulent fluid flow. The turbulent flow generating means is a plurality of convex portions 84 for generating turbulent flow fixed to the upper outer surface 12 of the lift generating unit 10. With this configuration, the peeling of the fluid lift generation unit 80 from the upper outer surface 82 is suppressed, and a larger amount of fluid is caused to flow along the upper outer surface 82 of the lift generation unit 80, so that the lift due to the Coanda effect is more reliably achieved.
