Embodiment Construction

[0017] Principle prototype specific parameters:

[0018] Wingspan 1.5M

[0019] Body length 1M

[0020] Powered by electric motor;

[0021] The take-off weight is about 1.5Kg;

[0022] Maximum take-off weight ≤ 2.5Kg;

[0023] Verify the controllability of various flight attitudes in three different modes: vertical take-off state, fixed-wing state and conversion state.

[0024] VTOL flight controls (see Figure 5 ):

[0025] Roll control: rely on the different lift generated by the rotors 7 on both sides to control the roll of the aircraft;

[0026] Pitch control: rely on the tilting of the wings 3 on both sides and the large rudder surface 2 under the rotor 7 to control the pitch of the aircraft;

[0027] Heading control: rely on the differential action of the large rudder surface 2 under the two rotors 7 to dynamically control the heading of the aircraft;

[0028] Transition flight status:

[0029] The UAV is transformed from the vertical take-off and landing state ...

Abstract

The invention relates to a multi-purpose vertical take-off and landing unmanned aerial vehicle, which belongs to aviation system technology. A flip-wing V-22 Osprey, in which pitching and heading in a vertical take-off and landing state are controlled through periodical variable pitch, is available for tiltrotor aircrafts internationally. The scheme is not available for the tiltrotor aircrafts in domestic at the present stage. The biggest difficulty for the multi-purpose vertical take-off and landing unmanned aerial vehicle is excessive flight condition of the unmanned aerial vehicle from the vertical take-off and landing state to a level-flight state. The multi-purpose vertical take-off and landing unmanned aerial vehicle can take off and land like a helicopter and can also fly like a fixed-wing aircraft; and through the adoption of a coaxial dual-rotor design, the load capacity of the multi-purpose vertical take-off and landing unmanned aerial vehicle can be improved within a limited rotor diameter space. At present, an unmanned aerial vehicle, which can take off and land vertically and can also fly for a long time, is expected for both military use and civil use.

Description

technical field [0001] The invention relates to a multipurpose vertical take-off and landing unmanned aerial vehicle, which belongs to aviation system technology. Background technique [0002] Internationally, there is a V22 "Osprey" of tilt-rotor aircraft that uses periodic pitch change to control the pitch and heading of the vertical take-off and landing state. There is no such program in China at this stage. The biggest difficulty for the multi-purpose vertical take-off and landing UAV is the excessive flight state of the aircraft from the vertical lift state to the level flight state. Contents of the invention [0003] The technical problem to be solved by the present invention is: the vertical take-off and landing unmanned aerial vehicle of the present invention not only overcomes the speed limitation of the helicopter, but also overcomes the space limitation of the take-off and landing of the fixed-wing aircraft. [0004] A multi-purpose vertical take-off and landi...
