Description

Technical Field

[0001] The utility model relates to the field of aviation science and technology, in particular to a vertical take-off and landing unmanned aerial vehicle for flight simulation. Background Art

[0002] Unmanned aerial vehicles can generally be divided into fixed-wing unmanned aerial vehicles and rotary-wing unmanned aerial vehicles according to their functions. Fixed-wing unmanned aerial vehicles have the advantages of long cruising time, long cruising distance, excellent aerodynamic performance, and good wind resistance, but fixed-wing drones also have inherent limitations: they require longer takeoff and landing runways, and even if they use catapult takeoff and parachute landing, they still require a larger operating space. The above shortcomings greatly limit the scope of use of fixed-wing unmanned aerial vehicles. Rotary-wing unmanned aerial vehicles use rotors to generate forces and torques to balance gravity and flight operations.

[0003] According to the Chinese patent publication number CN206125421U, the technical solution disclosed in the patent document is as follows: The utility model belongs to the field of aviation technology and relates to a vertical take-off and landing unmanned aerial vehicle, characterized by: comprising a fuselage, wings, engines, engine propellers, ailerons, horizontal tail, vertical tail, four landing brackets connected to the vertical tail (or wing or horizontal tail), multiple connecting arms connected to the fuselage (or wing or horizontal tail or vertical tail), multiple motors connected to the connecting arms, and multiple rotors connected to the multiple motors. The utility model provides a vertical take-off and landing unmanned aerial vehicle that can take off and land vertically like a rotary-wing aircraft, and can fly at high speed like a fixed-wing aircraft. It can also maintain the advantages of a fixed-wing aircraft such as long cruising time, long cruising distance, excellent aerodynamic performance, good wind resistance, etc., and can also fly with a large load and a large take-off weight.

[0004] The above patent has the following shortcomings: the camera installed at the bottom of the aircraft can capture the scene and data below the unmanned aircraft, and help the unmanned aircraft flight control, aerial photography tasks, modeling tasks, map drawing, etc. The camera at the bottom of the drone can also perform self-checks to ensure that the operation is in good condition, but the device is not convenient enough when the camera is disassembled and maintained during use. In view of this, we propose a vertical take-off and landing unmanned aircraft for flight simulation. Utility Model Content
