Tail-mounted unmanned vertical take-off and landing aircraft

Abstract

The invention discloses a tail-mounted unmanned vertical take-off and landing aircraft which comprises an aircraft body. Wings are arranged on the front portion of the aircraft body, four tail wings are arranged on the rear portion of the aircraft body, a telescopic caudal vertebra is arranged on the tail of the aircraft body and located behind the four tail wings, the aircraft body is internallyprovided with a warehouse, and the wings are provided with ailerons. The aircraft is high in propulsive efficiency, small in size, easy to detach and maintain, good in operation stability and good inwind resistance.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a tail-mounted unmanned vertical take-off and landing aircraft. Background technique [0002] Due to its low cost, good safety, and wide range of uses, traditional rotary-wing aircraft have low flying speed, short range, and complex mechanical systems for single-rotor helicopters. UAVs that use tilting propellers or tilting rotors are comparable to traditional unmanned aircraft. Compared with the aircraft, the flight speed is increased and the range is prolonged. However, it requires a complex, heavy, high-torque tilting mechanism. Some models require the wings to tilt together, which results in poor wind resistance for vertical take-off and landing. The wing is in a deep stall state, with poor maneuverability and stability. Regardless of the layout of the tail-mounted aircraft, only the propeller slipstream rudder when hovering has the problem of poor maneuverability...

Problems solved by technology

[0002] UAVs are low in cost, good in safety, and widely used. Traditional rotorcraft have low flight speed, short range, and complex mechanical systems of single-rotor helicopters. Although UAVs using tilting propellers or tilting rotors are different from traditional Compared with aircraft, the flight speed is increased and the range is extended, but it requires a complex and bulky large-torque tilting mechanism. Some models require the wings to tilt together, which leads to poor wind resistance for vertical take-off and landing. The wings are in a deep stall state, and the maneuverability and stability are poor; no matter what the layout of the tail-sitting aircraft is, the propeller slipstream rudder alone has the problem of poor maneuverability when hovering, especially when the conventional layout and the canard layout are resistant to vertical take-off and landing. The wind resistance is worse, and the geometric size will be larger, while the flying wing layout has poor stability and insufficient trimming ability in level flight
