Description
Be used for aircraft, particularly the rolling-swing device of this class VTOL version aircraft of helicopter.
The existing this aircraft of helicopter that resembles mainly is the screw propeller that rotates by around vertical axis, and promptly rotor provides lift and pulling force.From the mode of operation of rotor, it is always arranged air downwards with certain angle of attack, does not have the higher operating characteristic of the sort of efficient of flapping wing in the rotation process, and this efficient that makes rotor itself also is not very high.Simultaneously, when flying before helicopter, because of structural restriction, rotor can not be for producing forward the pulling force very big angle that tilts, and makes in the resultant lift isolated pulling force forward less relatively, thus the flight efficiency when flying before having reduced.This shows that this common rotor is applied in the VTOL version aircraft, and it is relatively low that it exists efficient, structurally be difficult for changing some significant disadvantages such as direction of pull on a large scale.
The objective of the invention is: design a kind of rolling-swing device, make it when keeping greater efficiency, also can in a big way, change direction of pull easily, with vertical takeoff and landing (VTOL) or the flat state that flies that adapts to aircraft with flapping wing operating characteristic.
This new rolling-swing device that is used for aircraft mainly comprises pivoted frame, roll transmission device that the wing and control rolls the wing etc.By main shaft internal frame and outrigger are fused, constitute pivoted frame, pivoted frame with level or slightly the state of being inclined upwardly be installed in the braced wing outer end of body, by transmission device by the engine installation driven in rotation in the body.Roll the wing and constitute, be contained in by the axle journal on the spar on the bearing of pivoted frame outer end, roll the wing and adopt two at least by spar and suit blade thereon, and with spindle parallel and symmetric arrangement.On main shaft or coaxial with main shaft, near the position of pivoted frame, be provided with the center gear of Be Controlled system manipulation, roll the wing and driven by center gear through transmission device by the flower wheel on the spar, both are transmission in the same way, transmitting ratio is 2: 1.
Since roll between the wing and the center gear specific operative relation, when rolling the wing and driven, roll the wing just with " angle of attack ", " flapping wing " equal angles state around main axis rotation, air-flow row to certain direction, thereby obtain antagonistic force.When rolling the wing with " flapping wing " state and air mutual action, because of rolling the wing air directly to be agitated downwards, this makes, and to roll the pulling force that the wing produces also maximum, and the work efficiency that rolls the wing is improved.Because only by control center's wheel, just can in very large range change the direction of pull of rolling-swing device easily, according to these characteristics, rolling-swing device is well suited for being used for resembling the aircraft of helicopter and this class need V of dirigible.Be easy to owing to change the direction of pull of rolling-swing device, this can further increase the flight alerting ability of aircraft.

The running principle of rolling-swing device is referring to Fig. 1, driving main shaft (7) at engine installation makes the pivoted frame (6) and the wing (16) that rolls on it press arrow (15) direction when rotating, roll the wing not only around main axis rotation, also driven rotation by relatively-stationary center gear (36) by transmission device, with specific angle Changing Pattern with the air mutual action, thereby air-flow (53) to the certain orientation venting, is made and rolls the wing itself and be subjected to antagonistic force, be i.e. the required pulling force of aircraft flight.Rolling-swing device is air-flow row downwards among the figure, produced shown in arrow (52) to upper pulling force.
Roll the wing (16) when main shaft (7) rotates, the angle of himself changes as shown in Figure 1.Forward to the process of position B from position A rolling the wing (16), roll the wing air (53) row downwards with state of angle of attack, produce shown in arrow (52) to upper pulling force.It is similar to the mode of operation of general screw propeller at the mode of operation of this angular range to roll the wing, and just the angle of attack is bigger, especially reaches 45 ° at the median vertical line place.For avoiding separating than the air-flow stall that ambassador rolls the wing back side because of the angle of attack, cause lift divergence, in specific embodiment, will on rolling-swing device, set up angle of attack reducing mechanism, and make the wing incidence of rolling that forwards this angular range to depart from original state, be reduced to position shown in the long and two-short dash line among the figure.The angle of attack reducing mechanism of being set up is just started to control to make and is used rolling the wing only when rolling-swing device produces vertically upward pulling force.Be tilted to preceding or during horizontal pull, roll the wing and produce still with original angle state running at rolling-swing device.
Rolling the wing (16) and forward to the C process of position from position B, is directly air (53) to be fanned downwards, rolls the wing with this angle and air mutual action, and suffered air resistance is exactly to upper pulling force.Roll wing running state at this moment and the wing of bird and agitate downwards promptly that " flapping wing " is identical, roll the wing and forward position C to from position B, cause is agitated downwards with the area of maximum, and what produced is also very big to upper pulling force (as shown in arrow 52), at this moment also the highest with the interactional efficient of air.
Roll the wing (16) and forward to the D process of position, also under state of angle of attack, resemble the screw propeller downwards, to produce pulling force (52) upwards air (53) row from position C.When rolling the position of the vertical axis of the wing (16) below forwarding to, although the angle of attack also reaches 45 °, be to be in lower position because of rolling the wing, at the centrifugal effect that rolls the wing with agitate downwards under the effect, air-flow can be flushed to and roll the wing back side, separates and stall does not take place.
Forward to from position D the A process of position rolling the wing, identical because of rolling wing moving direction with pulling force (52) direction, can not produce pulling force upwards, just the wind area with minimum turns over this angular range, makes and rolls the resistance minimum that the wing is subjected to.
After rolling the wing (16) and turning over position A from position D, begin again to rotate to position B, to continue to repeat above-mentioned rotation process,, produce pulling force upwards air row downwards.Rolling-swing device produces among the figure is vertically upward pulling force, when forwarding direction of pull to, control center wheel (36) is tilted to when preceding, roll the residing all angles of wing position and all will become very favourable, the vertical tension that makes the pulling force of generation can decomposite horizontal pull forward and make progress.
Compare with general screw propeller, rolling-swing device roll the branch that the wing (16) does not have front and rear edge, it is all very sharp wing in a kind of two ends, rolls the wing and is rotating and the changing front and back position of time rotational around main shaft to adapt to.Fig. 2 shows the aerofoil profile enlarged drawing that rolls winged petiole sheet (17), this wing be two arcs of symmetry, the edge at two ends is very sharp, section is also thinner, shape is fairly simple.Blade (17) is sleeved on the spar (18).
Rolling-swing device change direction of pull is taken turns by control center and is realized that the principle of center gear (36) Be Controlled system manipulation as shown in Figure 3.Rolling-swing device among Fig. 3 produces is vertically upward pulling force, as need pulling force forward to shown in Figure 4 be tilted to the place ahead to, control joystick (40), drive device (41), (42) of control system, making control piece (43) drive center gear (36) rotates along arrow (44) direction, the angle position of rolling the wing (16) will change thereupon, and direction of pull is forwarded to the preceding state that is tilted to shown in Figure 4.How many angles control center's wheel rotates, and just can allow direction of pull change how many angles.By control joystick (40), can be at an easy rate make direction of pull forward into, upwards or backward.
The structure of rolling-swing device in specific embodiment as shown in Figure 5, its pivoted frame (6) is by main shaft (7) internal frame (8) and outrigger (9) to be fused, main shaft (7) is a central siphon, is contained in by bearing (4) on the pivot shaft (3) in braced wing (2) outside.In the inboard of main shaft (7) flower wheel (11) is housed, the engine installation in the body can drive flower wheel (11) through the transmission shaft (13) and the driven wheel (12) of transmission device, makes main shaft (7), pivoted frame (6) and rolls the wing (16) rotation.Installed two on the pivoted frame (6) and rolled the wing (16), rolled the wing and be contained on the bearing (10) of internal frame (8) and outrigger (9), be arranged in main shaft (7) both sides symmetrically by the axle journal on it (19).If desired, also can arrange symmetrically that on pivoted frame (6) three are rolled the wing.Inside and outside pivoted frame (8), (9) are divided into three parts to the blade (17) on the spar (18), and the blade that is in midway location is bigger, and the blade of both sides is less relatively.
In rolling-swing device shown in Figure 5, rolling what adopt between the wing and the center gear is the two-stage chain drive.The angle of attack reducing mechanism that rolling-swing device is set up can be combined with this transmission device.The structure of transmission device as seen from the figure, the flower wheel (20) that respectively rolls on the thriving beam (18) is on the identical axial location, the stage transmission wheel (22) that goes up on relative transmission shaft (23) inboard by chain (21) and pivoted frame (6) links to each other, the one-level power wheel (24) that every transmission shaft (23) is gone up opposite side certain interval of then staggering mutually in the axial direction is connected with corresponding center gear (36) by chain (26)., roll the wing because of having adorned two on the pivoted frame here, corresponding center gear (36) also is to adopt two, and makes one, is positioned at the pivoted frame outside, is contained in and passes pivot shaft.(3) actuating spindle (37) outer end makes center gear pass through this actuating spindle and is handled by the control system in the body.
Whether adding angle of attack reducing mechanism in rolling-swing device, mainly is that the type by aircraft is determined.Resemble this whole raising forces of helicopter and all be under the situation about providing, just should add angle of attack reducing mechanism, roll the stall separation phenomenon that produces when the wing forwards upper position to elimination by rolling-swing device.The structure of angle of attack reducing mechanism as shown in Figure 6 and Figure 7, it is installed on the rolling-swing device that adopts the two-stage chain drive.As seen from the figure, angle of attack reducing mechanism mainly is to be made of the cam mechanism that is contained on the transmission shaft (23).To control transmission shaft (23) deflection because of cam mechanism, allow the angle of attack that rolls the wing change, transmission shaft (23) with its on one-level power wheel (24) between be to be connected with spring (28), make both can turn round 30 ° angle at least relatively.One-level power wheel (24) is contained on the gear wheel (27) of transmission shaft (23) by the decorative cover on the both ends of the surface (25), and spring (28) is located in the middle of two decorative covers, and its two ends radially withstand on gear wheel (27) and the one-level power wheel (24).Cam (31) is fixed on the outer end of pivot shaft (3), and the support (29) with two pinch rollers (30) is housed at the middle part of transmission shaft (23).When rolling-swing device produces vertically upward pulling force, the transmission shaft (23) that forwards upper position with pivoted frame (6) to can be fixed on cam (31) the control deflection of pivot shaft (3) outer end by support (29) and pinch roller (30), allow and roll the wing and reduce the angle of attack, avoid the air-flow stall at the back side to separate.
Cam (31) is fixed on such position, when rolling-swing device produces vertically upward pulling force, when pivoted frame (6) forwards to behind the position of about 45 ° of vertical axis by arrow (15) direction, just contact with cam (31) gradually with the pinch roller (30) on the support (29) of transmission shaft (23) rotation, force gear wheel (27) compression on the transmission shaft and the spring (28) between the one-level power wheel (24), allow relatively one-level power wheel (24) deflection of transmission shaft (23), roll the wing by stage transmission wheel (22) and chain (21) drive again and reduce the angle of attack.When rolling the wing and forward the vertical axis position on top to pivoted frame (6), slide pinch roller (30) on cam (31) also be raised to rise from, the angle of attack that rolls the wing is reduced to from original 45 ° does not produce about 15 ° that air-flow stall separates.After pivoted frame (6) turned over 45 ° of vertical axis, the pinch roller (30) on the support (29) also left cam (31), no longer is subjected to cam-controlled.If control center's wheel (36), the pulling force of rolling-swing device is forwarded to be tilted to preceding or horizontal direction, change because of angle also takes place the support (29) on the transmission shaft (24), the rotary motion trace that makes pinch roller (30) is away from cam (31), allow cam contact not pinch roller, angle of attack reducing mechanism is just no longer started to control to make and is used.
After setting up angle of attack reducing mechanism on the rolling-swing device, roll that transmitting ratio is 1: 1 between flower wheel (20) on the wing and the stage transmission wheel (22) on the transmission shaft, transmitting ratio is 2: 1 between the one-level power wheel (24) of transmission shaft opposite side and center gear (36).The installation site of transmission shaft (23) on pivoted frame (6) should accomplish that when pivoted frame rotates transmission shaft (23) does not bump with the cam (31) that is fixed on pivot shaft (3) outer end.
In rolling-swing device, roll between the wing and the center gear except that adopting the two-stage chain drive, Fig. 8 gives other two kinds of different transmission devices with embodiment among Fig. 9.The rolling-swing device that Fig. 8 describes has adopted the two-stage conical gear drive, in this transmission device, roll the power wheel (34) of power wheel (32), tween drive shaft (33) pivoted frame (6) on and the tween drive shaft opposite side of flower wheel (20) on the wing (16) and controlled by center gear (36) through being meshed.Center gear (36) is installed in actuating spindle (37) outer end, is handled by the control system in the body through this actuating spindle.What the rolling-swing device that Fig. 9 describes adopted is the single-stage chain drive, this is the simplest a kind of transmission device, two flower wheels (20) that roll on the wing (16) stagger in the axial direction mutually, are connected with center gear (36) on corresponding actuating spindle (37) outer end through chain (35) respectively.Because of there being two to roll the wing, center gear (36) also is two, and makes one, is contained in the outer end of actuating spindle (37).Because structural limitations, the transmission device among Fig. 8 and Fig. 9 can not be combined with angle of attack reducing mechanism.
The rolling-swing device of the foregoing description adopts all is by internal frame and the relatively large pivoted frame that is configured to outward, the pivoted frame that Figure 10 describes (6) then is to be made of the monomer members (14) that is contained on the main shaft (7), rolling the wing (16) is contained on the bearing (10) of pivoted frame (6) by the axle journal (19) in the middle part of the spar, blade (17) is contained in the both sides of spar (18), and two roll the wing (16) and the parallel and symmetric arrangement of main shaft (7).What this rolling-swing device adopted among the figure is the two-stage chain drive, also is two with rolling the center gear (36) that wing quantity adapts, and is sleeved on the inboard main shaft (7) of pivoted frame (6) after making one.The control piece (39) of center gear (36) green phase bonded assembly axle sleeve (38) and opposite side etc. is handled by the control system in the body.
In the given rolling-swing device of above each embodiment, the structure of pivoted frame mainly contains two kinds, a kind of is as shown in Figure 5 relatively large pivoted frame, another kind is a more small-sized pivoted frame as shown in figure 10, and rolling between the wing and the center gear of they can be selected three kinds of different transmission devices (two-stage chain gear, two-stage Bevel Gear Drive or single-stage chain gear) for use.In addition, be installed in the diverse location in the pivoted frame inboard or the outside, the also corresponding inboard or the outside that is arranged in pivoted frame of transmission device according to center gear.But, transmission device is arranged on the pivoted frame inboard,, makes the center gear diameter bigger, can cause flower wheel and other Transmission size of rolling on the wing to increase because of center gear is sleeved on above the main shaft.
Compare with general rotor, wanting that rolling-swing device shows is complicated a lot, and structural weight also increases to some extent.Rolling-swing device is used for aircraft, mainly is to turn to advantages such as very easy in order to utilize it to have the big and pulling force of area that efficient height, blade and air act on mutually.According to the characteristics that rolling-swing device had, it is used for this class such as helicopter, dirigible need the flexible aircraft that changes direction of pull still be particularly suitable.The subject matter that the restriction rolling-swing device is used is the intensity of rolling the wing, owing to roll the wing will be subjected to air and centnifugal force repeatedly when rotating direct effect, roll the wing and must have enough strength and stiffness, simultaneously enough anti-fatigue lifes will be arranged, to guarantee the safe flight of aircraft.But, the aspect that rolling-swing device is structurally also favourable has only a fulcrum (main shaft) to compare with the rotor of pure helicopter.The wing that rolls that is arranged on inside and outside unitized construction type of the employing pivoted frame of body both sides is equivalent to have four fulcrums, at this moment improves structural strength and is very important.
Figure 11 and Figure 12 have described two design plans that rolling-swing device is used for aircraft respectively.Figure 11 is the topology layout of a rolling-wing type helicopter, rolling-swing device (5) is arranged on the tip position of fuselage (45) rear side by braced wing (47), rolling-swing device is located at the fuselage rear side, be when coming balance to take off vertically, make fuselage face upward the moment of head because of rolling wing rotation for the weight of utilizing forebody.At the anterior downside of fuselage (45), be provided with front wing (46), when the helicopter horizontal flight, front wing on the fuselage (46) and braced wing (47) can produce lift greatly, turn to the lift deficiency that is caused with compensation because of rolling wing pulling force.The flying speed of this rolling-wing type helicopter is more or less the same with pure helicopter because of rolling the limit of wing rotating speed, but because rolling-swing device has higher efficient, flying distance is increased considerably.In addition, this rolling-wing type helicopter has saved the sort of antitorque tail-rotor on the pure helicopter.
Figure 12 is a kind of topological design of rolling-wing type dirigible, and the gondola of this dirigible (50) is fixed on air bag (48) below with four suspension elements (49), and rolling-swing device (5) is contained on the gondola rear positions by braced wing (51).Because the flying speed of dirigible is lower, it is very suitable adopting the very big rolling-swing device of this blade area, is expected to allow dirigible reach higher flight efficiency.
