Vertical take-off and landing fixed-wing UAV

Abstract

The invention provides a vertical take-off and landing fixed-wing unmanned aerial vehicle including a fuselage; wings are arranged at two sides of the fuselage; the fuselage is internally equipped with a foldable fuselage rotor wing; two sides of the fuselage rotor wing are equipped with fuselage slide plates; the wings are internally provided with a plurality of foldable wing rotor wings, and the top of each wing rotor wing is equipped with an openable-closable wing slide plate device. By adopting the structure, the unmanned aerial vehicle has the following beneficial effects that with adopting of forward driving and combination of the fuselage rotor wing and the wing rotor wings, switching between the vertical take-off and landing and fixed wing flight is convenient to realize. The unmanned aerial vehicle having the structure conveniently hovers at any time during task implementing, so that a camera can conveniently perform fixed-point observation, and at the same time, runways and ejection equipment are not required during take-off and landing. With the combination of the fuselage rotor wing and the wing rotor wings, the balance of the whole fuselage is convenient to control. With the use of the hidden type fuselage rotor wing and the hidden type wing rotor wings, no interference exists between the vertical take-off and landing mode and the fixed wing flight mode, and the size of the wings is not required to be increased. The lifting efficiency of air stream is high.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a vertical take-off and landing fixed-wing unmanned aerial vehicle. Background technique [0002] Fixed-wing aircraft that take off and land vertically. This type of aircraft has similar functions to helicopters. It can take off and land vertically without using a runway. The difference is that this type of aircraft can accelerate from a hovering state to level flight through power tilting And transition to fixed-wing flight mode. For unmanned aerial vehicles, the fixed-wing solution of vertical take-off and landing can make the unmanned aerial vehicle land at the predetermined position. control advantage. [0003] At present, the practical vertical take-off and landing fixed-wing aircraft are mainly AV-8 Harrier fighter jet, V-22 Osprey tilt-rotor aircraft, and F-35 fighter jet. The AV-8 Harrier uses a Pegasus engine, and on the basis of a jet engine, it adopts a thrus...

Problems solved by technology

[0006] However, for UAVs, the structure is still too complicated, and in order to achieve practical stiffness, the requirements for structural accuracy and material rigidity are too high, the overall cost is high, and the balance of the body is difficult to control

[0007] In the prior art, there is also a scheme in which the rotor is embedded in the wing. In this scheme, a huge wing is provided on the body, and a through hole that penetrates up and down is provided on the wing. The rotor is arranged in the through hole. The rotor takes up a lot of space, the air fluid lift efficiency of the wing is not ideal, and the body is also relatively bulky
