Description

A kind of vertical takeoff and landing horizontal flight unmanned plane
Technical field
The utility model relates to a kind of vertical takeoff and landing horizontal flight unmanned plane, belongs to aerospace flight vehicle design field.
Background technology
At present, the fields such as unmanned plane widespread use is taken photo by plane, plant protection, forestry, fire-fighting, investigation, anti-terrorism, the various new opplication emerged in an endless stream also proposes new requirement to the design of unmanned plane and optimization.Cruise duration is the important indicator assessing unmanned plane performance, and technology new in a large number and means continue to bring out the cruise duration of being devoted to improve unmanned plane.Fixed-wing unmanned plane is self-contained power source only for providing thrust or pulling force relative to the advantage of rotor wing unmanned aerial vehicle, and the lift produced by wing and fuselage overcomes gravity makes fixed-wing unmanned plane maintain the state of airflight.By contrast, the power source overwhelming majority that rotor wing unmanned aerial vehicle is self-contained is for overcoming the gravity of body.The fixed-wing unmanned plane of identical take-off weight has longer cruise duration than rotor wing unmanned aerial vehicle.From the viewpoint of usability, rotor wing unmanned aerial vehicle does not need runway, almost can take off from arbitrary geographic position and execute the task, and taking off and landing of fixed-wing unmanned plane is subject to the restriction in place all greatly.Vertical takeoff and landing horizontal flight unmanned plane is the combination of fixed-wing and rotor wing unmanned aerial vehicle, the function of using rotor wing unmanned aerial vehicle takes off vertically or lands, abandon the dependence to place, after being increased to certain altitude, family planning rotates to level flight condition, the lift utilizing fuselage to produce overcomes gravity, saves a large amount of power sources.
The technical barrier of vertical takeoff and landing horizontal flight unmanned plane is that lift mode is in the conversion of level flight condition, improves the stability of state of flight conversion as far as possible and reduce conversion difficulty and will contribute to further developing and applying of this kind of unmanned plane under flight controls reliable and stable prerequisite by the structure design of body.
Summary of the invention
Technical problem to be solved in the utility model is to overcome prior art defect, provides a kind of vertical takeoff and landing horizontal flight unmanned plane.
Principle of work of the present utility model is: on conventional vertical landing horizontal flight unmanned plane basis, increase reversible auxiliary rotor in body afterbody, utilize reversible auxiliary rotor, take off vertically at unmanned plane or in descent, keep auxiliary rotor turning cylinder parallel with main rotor turning cylinder to increase unmanned plane lift; Unmanned plane vertical flight with adjust reversible auxiliary rotor in the switching process of horizontal flight and make its turning cylinder vertical with main rotor turning cylinder with the pitching moment increased in flight attitude switching process; Adjusting reversible auxiliary rotor when unmanned plane is in completely and puts down and fly state makes turning cylinder parallel with main rotor turning cylinder, and increase unmanned plane puts down tractive force when flying.
In order to solve the problems of the technologies described above, the utility model provides a kind of vertical takeoff and landing horizontal flight unmanned plane, comprises main rotor, unmanned aerial vehicle body, tailplane, vertical tail and reversible auxiliary rotor.Described main rotor is positioned at both sides, unmanned plane top, respectively by respective electrical motor driven rotary, for lift when unmanned plane provides vertical and landing takeoff and flat fly time pulling force.Described tailplane is positioned at unmanned plane organism bottom both sides, by servos control for unmanned plane provides pitching moment.Described vertical tail is fixed on unmanned plane organism bottom both sides, provides supporting role during unmanned plane vertical and landing takeoff ground, and the valve action of unmanned plane tail wind when playing airflight.Described reversible auxiliary rotor is positioned at unmanned plane body rear center position, and the rotating shaft direction of reversible auxiliary rotor can adjust according to the needs of unmanned plane during flying attitudes vibration.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of vertical takeoff and landing horizontal flight of the utility model unmanned plane, comprises main rotor (1), unmanned aerial vehicle body (2), tailplane (3), vertical tail (4) and reversible auxiliary rotor (5).
As depicted in figs. 1 and 2, main rotor (1) is positioned at both sides, unmanned plane top, respectively by respective electrical motor driven rotary, is pulling force when lift when unmanned plane provides vertical and landing takeoff and horizontal flight.Vertical tail (4) is fixed on unmanned plane organism bottom both sides, provides supporting role during unmanned plane vertical and landing takeoff ground, and the valve action of unmanned plane tail wind when playing airflight.
As shown in Figure 1, tailplane (3) is positioned at unmanned plane organism bottom both sides, by servos control for unmanned plane provides pitching moment.
As shown in figures 1 and 3, reversible auxiliary rotor (5) is positioned at unmanned plane body rear center position, is connected with fuselage by both sides rotating shaft (6) with revolute pair, auxiliary rotor screw propeller and provide the motor of power be installed on auxiliary rotor pole (7) central authorities.The rotating shaft direction of reversible auxiliary rotor can adjust according to the needing the rotational angle of control both sides rotating shaft (6) of unmanned plane during flying attitudes vibration.
As shown in Figure 4, when unmanned plane takes off vertically from ground or vertical landing prepares to reclaim, adjust reversible auxiliary rotor (5) turning cylinder parallel with main rotor (1) turning cylinder, increase unmanned plane lift.
As shown in Figure 5, when unmanned plane forwards level flight condition to by lift mode or forwards lift mode to from level flight condition, adjust reversible auxiliary rotor (5) turning cylinder vertical with main rotor (1) turning cylinder, increase unmanned aerial vehicle body pitching moment, reliablely and stablely realize flight attitude conversion.
As shown in Figure 6, when unmanned plane keeps level flight condition, adjust reversible auxiliary rotor (5) turning cylinder parallel with main rotor (1) turning cylinder, increase the pulling force of unmanned plane flight forward.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from utility model works principle, these improvement also should be considered as protection domain of the present utility model.
