Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Embodiment
As shown in Figure 1, the embodiment of the invention discloses the Fixed Wing AirVehicle that can be vertically moved up or down of one kind, including body 1 with And it is set to the machine left wing 2 on body 1 and machine right flank 3, aircraft integral installation in machine left wing 2 and machine right flank 3 has one The rotary shaft 4 and rotary shaft 4 extends transversely through entire body is also fixedly mounted on 4 outer surface of rotary shaft for being located at 1 position of body There is a circle gear 5, which passes through a pneumatic rotary device 6 control rotation.
As shown in Fig. 2, above-mentioned pneumatic rotary device 6 specifically includes in the embodiment of the present invention: cylinder 61, gear drive 62 and angle demodulator 63.Wherein 61 shape of cylinder is integrally in rectangle, and piston is located at the right end in cylinder cylinder;Gear drive machine Structure 62 is installed on cylinder piston and cylinder block is formed by space comprising the rack gear row one being fixed on the inside of cylinder left end 621 and the rack gear row 2 622 that is connected with cylinder piston medial surface, rack gear row 1 and rack gear row 2 622 are in opposite up and down Setting, and rack gear row 1, rack gear row 2 622 and the gear 5 of 4 outer surface of rotary shaft are intermeshed, that is to say, that rack gear row 1 and rack gear row 2 622 relative in rotary shaft 4 gear 5 be symmetrical arranged.When cylinder piston is mobile, rack gear row will push 2 622 is mobile, since rack gear row 1, rack gear row 2 622 and the gear 5 of 4 outer surface of rotary shaft are intermeshed, therefore can band Moving gear 5 and rotary shaft 4 rotate, the final wing rotation for driving aircraft.
Further, angle demodulator 63 includes: the piston rod being connected on cylinder piston lateral surface, is located on piston rod Displacement sensor, the motor for pushing piston rod mobile and the controller being connected with motor and displacement sensor.Angle tune Section device 63 connect setting with piston rod, for limiting the shift position of piston, specifically: power is provided by motor, passes through position Displacement sensor incudes moving distance, and the information that controller feed back by displacement sensor controls the start and stop of motor, the controller and Aircraft supervisory control desk is connected.
The rack shapes that rack gear row 1 and rack gear arrange 622 2 outboard ends are also designed as by the embodiment of the present invention simultaneously Greater than other rack gears, when piston is pushed to the end of rack gear row, which can also withstand piston, and it is further forward to limit it Movement, and then assist angle demodulator 63 realize to rotary shaft 4 rotate angle accurate control.
In the embodiment of the present invention, the junction of machine left wing 2, machine right flank 3 and body 1 is equipped with inclining rotary mechanism, the inclining rotary mechanism Be able to achieve 90 ° of rotations of machine left wing 2 and machine right flank 3, Ji Ji left wing 2, machine right flank 3 rear end from the upward 90 ° of rotations of horizontality To vertical state.
In the embodiment of the present invention, the rear end of machine left wing 2 and machine right flank 3 is respectively symmetrically equipped with several propeller power dress Set 7, it is preferred that the propeller power device 7 is provided with two or three on each wing, all propeller power devices 7 are connected with the engine device in body 1.When aircraft needs VTOL or hovering, propeller power dress It sets 7 and is rotated into 1 top of body, while wing state in a vertical shape, provide the lift to fly upwards for the aircraft;Work as aircraft When needing to accelerate flight forward, propeller power device 7 is rotated into 1 rear of body, while wing is in a horizontal state, and flies for this The thrust of row device offer flight forward.
In order to advanced optimize technical solution of the present invention, the engine device of control propeller power device 7 in body Two should be at least arranged, general 4-8 platform is advisable, and as needed, which can choose whirlpool paddle, also can choose Turbofan is either arranged in pairs or groups simultaneously using two kinds or three kinds of different engine devices, so that propeller power device 7 has enough Big lift and thrust.
If as shown in figure 3, the front and back both sides of 3 upper surface of Zhong Ji of embodiment of the present invention left wing 2 and machine right flank are symmetrically installed with Dry gas power device.This is because the wing of aircraft is generally all very heavy, the machines such as rotary shaft 5, pneumatic rotary device 6 are relied solely on Tool transmission mechanism is likely difficult to that wing is made to obtain effect of preferably verting, and rotates the mill to mechanical transmission mechanism for a long time Damage consumption is also very big, therefore is based on this, and the present invention is additionally arranged several jet power units again, which is mainly rotation The nozzle 8 of wing provides compressed air, while controlling the flow of compressed air, realizes wing by jet reaction Vert comprising air compressor, dried-air drier, air accumulator, filter, normally opened/normally closed solenoid valve, electric control valve with And safety valve, be sequentially connected with rubber hose by steel pipe between each device together with, nozzle 8 is also connected with outside electric control valve. As shown in Figure 1, nozzle 8 is symmetrically arranged on the front and back both sides of 3 upper surface of machine left wing 2 and machine right flank, small-sized pressure is installed at nozzle 8 Power, temperature and velocity sensor, these sensors are connected with aircraft supervisory control desk.Specific workflow are as follows: pass through collection It flows ring and sensor signal is transmitted to non-rotating portion by rotating part, then transmit it to aircraft supervisory control desk, master control Platform is analyzed by pressure, temperature and the velocity amplitude to air-flow at the jet hole measured, final to control on jet power unit Electric control valve realizes the reasonable control to spray air flow, and then control the tilt angle of wing by adjusting its opening and closing degree Degree.
Since the high pressure gas humidity come out from air compressor machine is very big, its corruption to pipeline and valve and instrument in order to prevent Erosion, the present invention have concatenated drying machine and filter in jet flow pipeline.It is furthermore preferred that there are two filter settings, two filterings Device is sequentially connected with, to ensure that high pressure gas is constantly in reasonable humidity range.
The present invention has two kinds of offline mode of gyroplane and fixed wing aircraft simultaneously, by supervisory control desk to both of which Mutually conversion, make the aircraft can VTOL, hovering but high speed, efficiently cruise, compared to existing flight Device, practicability with higher.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one The widest scope of cause.
