Description

Lift-Generating Devices}

The technical field of the present invention relates to lift generators.

In an aircraft, lift is a necessary condition for flight activities to take place. In the patent, an example of implementing lift strong enough to implement a flying car using rotorcraft technology is the Republic of Korea Patent Registration No. "10-1468339". In the Republic of Korea Patent Registration No. "10-1468339", a helicopter-type flying car was announced. The helicopter-type flying car was able to fly by installing a rotor used in a helicopter on the roof of the car body. This technology is worthy of evaluation as an attempt to combine aerospace technology with automobiles. However, the lift generator used in the helicopter-type flying vehicle requires that the rotational sectional area of the rotor to give lift to the vehicle is much larger than the area of the roof of the vehicle. It is unfortunate that the wind due to the lift generated by the propeller on the car body roof area again presses the car body roof down, so that lift cannot be generated as a result. In other words, only the lift generated in the area other than the body roof area is actually used to lift the car.

In addition, in Korean Patent Registration No. 10-1145960, as a means for generating strong lift, a jet engine is installed on the wing of a fixed-wing aircraft to generate lift by blowing strong wind in a direction parallel to the wing. The above invention has the advantage of enabling large aircraft to take off and land vertically by generating strong lift. However, even in daily use of jet engines, there are risks due to flames and heat. Therefore, a means for generating stable and strong lift is required.

In order to solve the problems of the prior art, the present invention proposes a more powerful lift generator than the conventional propeller.

In order to achieve the above object, the present invention provides a lift generating device,

The impeller blades are configured to further include a rotating frame that connects one side of them to each other and fixes them integrally.

Additional lift blades are further provided on the outer periphery of the impeller blades, and the lift blades are generated by the impeller blades and change the direction of the exhaust air, which is the air flow that is parallel to the lift plate and directed outward, more downward, thereby generating additional lift. is configured to generate

Tesla disks stacked in the upward direction of the lifting plate while maintaining the spacing, when the impeller bottom plate rotates, the air on the lifting plate escapes in the outward direction parallel to the lifting plate in the form of a vent due to the boundary layer effect caused by the Tesla disks, resulting in lift The pressure at the top of the plate is lower than the pressure at the bottom of the lifting plate to generate lift.

The above Tesla disc may have a rough surface in order to increase the boundary layer effect.

Additional lifting wings are further provided on the outer periphery of the Tesla disk, and the additional lift wing is generated by the Tesla disks and changes the direction of the air flow, which is the air flow parallel to the lifting plate and outward, to a downward direction to provide additional lift. is configured to generate

plate-shaped lift plate; When the side propeller rotates while the side propeller is mounted on one end of the rotating shaft of the side propeller, which is the rotational axis of the fixed power source installed on the lift plate, the air on the lift plate escapes in the outward direction parallel to the lift plate in the form of an exhaust air. The pressure at the top is lower than the pressure at the bottom of the lifting plate to generate lift.

The power source may be composed of a configuration in which side propellers are respectively installed at both ends of the rotation shaft of the side propeller.

Additional lifting wings are further provided on the path where the air on the lifting plate leaves the lifting plate in the form of a tailwind, and the additional lifting wing changes the direction of movement of the tailwind more downward to generate additional lift. It consists of

In addition, power sources equipped with side propellers may be installed in multiple stages in the upper direction of the lifting plate to increase lift. Similarly, a plurality of side propellers interlocked with each other using a single power source, an idle pulley, and a timing belt may be installed in multiple stages upward on the lifting plate.

In addition, the present invention is a lift generating device,

From the outside of the side of the plate-shaped lifting plate to the lower part of the lifting plate, the pipe (lifting plate through-hole) that is integrated with the lifting plate penetrates the lifting plate from the bottom to the top and introduces air in an upward direction, so that the upper part of the lifting plate A lifting plate through-pipe 560 may be installed and configured to reduce the average downward speed of air by causing collision with air flowing in at high speed in the downward direction.

Hereinafter, the present invention will be described in detail with reference to the drawings. It should be noted that like elements in the drawings are indicated by like numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

In order to eliminate confusion, the term "centrifugal impeller" is first defined. As shown in FIG. 1, the centrifugal impeller is a “vane 90 integrated with the rotating shaft 50 is radially disposed around the rotating shaft 50 that rotates by receiving power from the power source 40, so that the rotating shaft ( 50) and the wing 90, by centrifugal force or frictional force generated when the wing 90 rotates, the fluid present in the rotation range R of the wing is discharged in the form of the exhaust air 110 in a direction perpendicular to the axis of rotation 50 It is a machine". Since several types of centrifugal impellers have already been released and are often used by those skilled in the art in the field, the present invention focuses on a method of generating lift using the centrifugal impeller. Hereinafter, for convenience, "centrifugal impeller" is simply referred to as "impeller", except where it is particularly emphasized.

First, the lift generator presented in the present invention, which is used by an aircraft to generate lift to lift its own weight and the weight of the person(s) on board, will be described in detail. 1 shows that an impeller sharing rotational shafts 50 and 51 with the propeller 30 is mounted between a propeller 30, which is a lift generator used in a conventional drone, and a lift plate 60 that generates lift, and there is. The impeller has a rotating body frame 100 surrounding the impeller rotating shaft 50 attached to the impeller bottom plate 80 integrated with the impeller rotating shaft 50, and the impeller blades 90 around the rotating body frame 100. One side is attached to the structure. The rotary frame 100 shown in FIG. 1 (a) has a hollow inside, but impeller blades 90 may be attached to the hollow inside. In addition, FIG. 4 shows a shape in which the lift wing 180 surrounds the impeller from the side. The reason why the impeller and the lifting wing 180 are mounted under the propeller 30 is to generate lift stronger than the lift generated only by the propeller 30. Since the fact that the conventional propeller 30 generates lift is a well-known fact, in the present invention, the impeller and the additional lift blade 180 can each generate additional lift to the lift plate 60. Explain in detail.

1 is a perspective view (a) and a cross-sectional perspective view (b) showing that the impeller rotation shaft 50 vertically penetrates the center of the lifting plate 60. The lifting plate 60 may be a flat plate having a predetermined thickness, a curved surface, or a surface in which a flat plate and a curved surface exist at the same time.

In addition, a lifting plate support frame (not shown) is integrated with the lifting plate 60 on the underside of the lifting plate 60, so that the power source and lifting additional wing support pillar 190 presented in the present invention are integrated with the lifting plate support frame. , It can be integrated by attaching the side air inflow prevention base support pillar 201). So, if it is not simple to attach a certain part to the lifting plate 60, the same function can be achieved even if it is attached to the lifting plate support frame.

In addition, as shown in FIG. 2, the power source for rotating the impeller rotating shaft 50 is mounted on the top of the lift plate 60 in the same direction as the impeller (hereinafter referred to as "upper") based on the lift plate 60 Alternatively, as shown in FIG. 1, it may be mounted at the lower end of the lifting plate 60 in the opposite direction (hereinafter referred to as "lower side"). In the present invention, the power source may be a motor or an engine. At this time, the power source may be integrated with the lifting plate support frame. The description of the power transmission method between the impeller rotational shaft 50 and the power source is omitted because it belongs to the local one in the present invention. As shown in FIG. 1, when an impeller having a height H and a rotation radius R receives rotational force from a power source 40 and rotates at high speed on the lifting plate 60, a downdraft 120 is generated from the top to the bottom of the impeller, and the downdraft 120 is generated. It is known knowledge that the airflow 120 is eventually discharged to the outside of the lifting plate 60 in the form of exhaust air 110 due to interaction with the impeller blades 90 between the rotation radius R and the height H of the impeller. At this time, the air density is thinner and the pressure is lowered closer to the lift plate 60, so the fact that the lift plate receives lift upward due to the atmospheric pressure 130 below the lift plate is explained in detail in Korean Patent Registration No. 10-1145960 there is. Investigating the registered patent, the higher the height H of the impeller or the revolutions per minute RPM of the impeller, the higher the lift plate receives a stronger lift than when using a conventional propeller. At this time, in order to increase the speed of the exhaust air by using a sirocco fan, as shown in FIG. can also be fitted. As described above, the device that generates lift on the lift plate using an impeller is called an "impeller-type lift generator".

Hereinafter, another type of impeller for discharging air to the outside of the impeller rotation radius R will be described in detail. 3 is a plan perspective view (above) of stacking a plurality of disks (Tesla disks 203) with a hole in the middle on the impeller bottom plate 80 along the impeller rotation shaft 50 while maintaining a predetermined distance with spacers (not shown). and a cross-sectional perspective view (below). The impeller bottom plate 80 is integrated with the impeller rotating shaft 50 while being parallel to the Tesla discs 203. The stacked Tesla disks 203 as described above are called a disk array. A hole is drilled in the Tesla original plate 203 so that the Tesla original plate support pillar 204 can pass therethrough. The Tesla disk support pillar 204 is integrated with the impeller base plate 80 and serves to integrate the impeller base plate 80 and the Tesla disk 203. The description of the method of integrating the Tesla disc support column 204 with the impeller base plate 80 is omitted because it belongs to a branch in the present invention. The spacer has a predetermined length and has a shape surrounding the Tesla disc support pillar 204. The length of the spacers forms the spacing of the Tesla discs 203. When the disk array rotates at high speed, the "disk array" plays the role of the impeller used in the present invention (the role of discharging air in the form of exhaust outside the rotation radius R) by the academic term "boundary layer effect" in 1913 It is a known technology already published in (see US Patent 1061142 1913.5.6 NIKOLA TESLA Turbine Patent). At this time, since the total stacking height of the disk array corresponds to the total impeller height in the present invention, the disk array can be used as a lift generating device. In constituting the disk array presented in the present invention, similar to the lift generator using a sirocco fan, the internal disk array 150 with a small radius of rotation may be configured within the external disk array 160 with a large radius of rotation. In addition, the surface of the Tesla original plates 203 constituting the disk array may be roughened, and the technique of roughening the surface is a technique commonly used in daily life. The reason why Tesla disks are used as lift generators is that they are almost silent. This is a great advantage compared to other lift generators that generate noise that interferes with daily life. The lift generator made using the disk array will be referred to as a "disk array type lift generator".

So far, it has been described in detail that lift can be generated in the lifting plate 60 using the impeller and the disk array. In order to additionally generate lift other than the lift plate 60, the lift generator of the present invention uses a cone-shaped or dome-shaped lifting wing 180 with an open top portion as shown in FIG. 4(a). can include more. Here, since the lifting wing 180 must include an impeller therein, it is preferable that the radius of the open section is larger than the impeller rotation radius R, and the apex portion faces upward. The additional lifting blades 180 may be used in multiple directions upward to the lifting plate and are symmetrically positioned with respect to the impeller rotational shaft 50. The lift wing 180 is a lifting wing support pillar 1 (190) or a bar-shaped lift wing having a plurality of predetermined thicknesses extending upward in a state in which one side is attached to the lift plate 60. It is attached to and disposed on the support pillar 2 (195). In other words, in the case of the lifting wing support pillar 1 (190), as shown in FIG. After cutting out a predetermined area as much as possible, the lift-added wings 180 are inserted into the cut-out gap to integrate and fix the inserted state. When air molecules flowing from the impeller to the lift plate 180 fixed as described above are parallel to the lift plate but directed to the outside of the lift plate at high speed in the form of a tail air 110, the lift wing 180 is the tail wind ( 110), it is known knowledge that the lift wing 180 obtains lift by increasing the downward velocity component. This is similar to how the wings of a fixed-wing aircraft gain lift. In addition, since the method of integrating and fixing between the lifting wing support pillar 2 (190) and the lifting wing 180 belongs to a branch in the present invention, description thereof will be omitted. In the present invention, when referring to an additional lifting support column, it means the additional lifting support column 1 (190) or the additional lifting support column 2 (195).

When the plurality of lift blades 180 are used, air molecules outside the lifting plate 60 through between the lift blades 180 from the outside of the side, not from the top or bottom, the impeller rotation radius R In order to prevent inflow into the inside, an empty cylinder attached to the lifting wing support column 190 or a hollow dome-shaped cylinder with a top portion cut off can be used as the side air inflow preventer 200 ( See Fig. 4(a)). In addition, the side air inflow preventers 200 have a bar shape and are radially arranged at regular angular intervals in a state attached in parallel to the lifting plate at the bottom of the lifting plate 60, and then the lifting plate 60 It can be attached to a plurality of side air inflow prevention base support pillars 201 bent upward at a predetermined angle at a point larger than the radius. (See FIGS. 4(c) and (d))

In addition, in order to prevent air molecules from entering the impeller rotation area on the side of the lift generator, a wing anti-reflective device 140 is added to bend the ends of the impeller blades 90 at a predetermined angle in the direction in which the wings are bent. It can also be used as (see Fig. 1).

In the lift generator of the present invention, in order to secure mechanical stability when the impeller rotation shaft 50 is long, the impeller rotation shaft support 290 and the impeller rotation shaft support bearing 300 may be used. In other words, as shown in FIGS. 4(a) and (c), the power source 40 is mounted in the center of the lifting plate 60, and the lifting wing 180 surrounding the lifting plate 60 has one end of the lift plate 60. In the structure attached to the plurality of lifting wing support pillars 190 fixed to the plate 60, the impeller rotation shaft support bearing 300 surrounding the impeller rotation shaft 50 is mounted on the top of the impeller rotation shaft 50, and the An impeller rotation shaft support 290 having a curved bar shape connecting the top of the impeller rotation shaft support bearing 300 and the lifting force support column 190 is installed to support the impeller rotation shaft support bearing 300.

In the above, the propeller 30 of the conventional drone and the impeller or disk array installed under the propeller 30 to generate additional lift independently and the impeller or disk array generates additional lift due to the exhaust air 110 discharged It was shown that the lifting wing 180 (s) can be used as a part of the lift generator.

Hereinafter, a method of generating lift by discharging air to the outside of the lifting plate by installing the side propeller 530 on the lifting plate 60 will be described in detail.

When the rotation axis of the power source integrated with the lift plate is horizontal to the horizontal plane, the side propeller 530(s) is mounted on one or both ends of the side propeller rotation shaft 550, as shown in FIGS. 5(a) and (b), respectively. Thus, those skilled in the art will easily understand that a "side propeller type lift device" can be implemented. This is because the concept of generating lift by discharging the air on the lifting plate to the outside of the lifting plate 60 is the same. When the side propellers 530 are mounted on both ends of the side propeller rotating shaft 550, there is one end and one end. Because the reaction of the propellers acting on the axis of rotation is offset, the durability of the power source can be further increased and the number of power sources can be reduced. Because. For convenience, in referring to the lift generator using the side propeller as described above, the device for generating lift by mounting the side propeller on only one end of the propeller shaft is called "side propeller type lift device 1", and both ends have side propellers The device for generating lift by mounting is called "side propeller type lift device 2", and when referring to both types of lift devices, it will be called "side propeller type lift device".

In the "side propeller type lift generator", the installation of the plate-shaped lift wing can be installed at a position facing the exhaust air on the path of the exhaust air 110 as shown in FIG. 5 (a) or (b). Those skilled in the art will be readily apparent. In all cases of the present invention, the lift wing serves to generate additional lift by further directing the direction of the tail air 110 downward. In this case, if necessary, if the side air inflow preventer 200 is installed, it is preferable to install it perpendicular to the horizontal plane on the lifting plate 60 along the direction in which the exhaust air passes (FIG. 5 (c)). In the "side propeller-type lift generator", the power sources 40 equipped with the side propellers 530 may be mounted in multiple stages in the upward direction to increase lift, but the description of the mounting method is in the present invention. It belongs to the peripheral, so it is omitted. Similarly, a plurality of side propellers 530 in one power source 40 are interlocked with each other using an idle pulley 551 and a timing belt 552 as shown in FIG. 5 (d), and the lifting plate 60 ), those skilled in the art will appreciate that it can be installed in multiple stages upwards.

Hereinafter, a method for increasing the speed of exhaust wind discharged from the lift plate to the outside of the lift plate in the three types of lift generators (impeller type, disk array type, side propeller type lift generator) presented in the present invention will be described. do. An increase in the speed of the tailwind is a necessary condition for increasing the lift of the lift plate. In fluid mechanics, the continuity equation means that when the amount of fluid passing per unit time (here, exhaust air) is constant, the speed is inversely proportional to the size of the cross-sectional area through which the fluid passes. Therefore, it is known knowledge that the speed of the exhaust air increases when the exhaust air is passed through the tube, the tube is gradually narrowed, and then discharged onto the lifting plate.

In the present invention, when a desired amount of lift can be generated in an "impeller-type lift device" or a "disk array-type lift device," the propeller 30 mounted on the top of the lift devices may not be required. In other words, at the beginning of the discussion of the present invention, the discussion was developed with the intention of additionally generating lift by placing an impeller under the conventional propeller 30, but in the end, the propeller 30 may be removed, It is possible to configure a lift generator that can be attached as needed. In addition, as the propeller used in the present invention, multi-lobed propellers including a two-lobed propeller may be used.

In addition, in the lifting plate 60 of the three types of lifting devices presented in the present invention, as shown in FIG. 6, the lifting plate is integrated with the lifting plate from the outside of the side of the plate-shaped lifting plate 60 to the lower part of the lifting plate 60. Air flowing in from the upper part of the lifting plate 60 at a high speed as the introduced pipe (the lifting plate through-pipe 560) penetrates the lifting plate 60 from the bottom to the top and introduces air in an upward direction It may have a lifting plate through-tube 560 that reduces the pressure on the lifting plate by reducing the average downward speed of air by causing collision with the lifting plate. In addition, when the lifting plate through-pipe 560 passes through the upper portion of the lifting plate 60, the portion of the pipe exposed to the upper part of the lifting plate 60 may be bent at a predetermined angle. In addition, the lifting plate penetration pipe 560 outside the side of the lifting plate 60 can be bent to be perpendicular to the horizontal plane (see FIGS. 6(b) and (c)). In addition, by cutting and connecting the sharply curved corner of the lift plate through-pipe 560, the air flow can be smoothed (see FIG. 6(c)). In addition, the lifting plate penetration pipe 560 can also serve as the "lifting plate support frame" proposed in the present invention.
