Vertical take-off and landing aircraft with distributed power unit configuration

Abstract

The invention discloses a vertical take-off and landing aircraft with distributed power unit configuration. The vertical take-off and landing aircraft with the distributed power unit configuration comprises an aircraft body, aircraft wings, an empennage and propellers. The aircraft body is of a semi-monocoque structure, and comprises a nose, a middle fuselage and an aircraft tail. The middle fuselage of the aircraft body is a cargo bay. The aircraft wings are arranged on the two sides of the aircraft body in a left-right symmetry mode. The aircraft wings are of double-beam semi-monocoque structures and connected with the aircraft body through reinforced frames. Auxiliary lifting wings are arranged at the rear edges of the aircraft wings correspondingly. End-plate type winglets are arranged at the wingtips of the aircraft wings correspondingly. According to the vertical take-off and landing aircraft with the distributed power unit configuration, the distributed propelling unit configuration is adopted, so that the aircraft can have a low rotor disk load and the high propelling efficiency during the vertical take-off and landing processes; a combined control mode combining the motor rotating speed / the propeller pitch with a propeller slip flow rudder is adopted, so that the control efficacy is high; tailless flying wing configuration is adopted for a fixed wing face, the size of the aircraft is decreased, the structure is more compact and easy to detach and maintain, and the wind resistance is good in the vertical take-off and landing stages compared with conventional configuration and a canard configuration.

Description

technical field [0001] The invention relates to a micro-aircraft, in particular to a vertical take-off and landing aircraft with a distributed power device layout. Background technique [0002] Vertical take-off and landing aircraft usually include helicopters, rotorcraft, flapping wing aircraft, tilting rotor aircraft, tail seat vertical take-off and landing aircraft, and vertical take-off and landing aircraft equipped with lift fans or vector propulsion devices. The structure of the tail seat vertical take-off and landing aircraft is simple, and the vertical flight and the horizontal flight use the same power system fixed to the body, which has high reliability and does not have the waste weight caused by multiple power systems. [0003] The vertical take-off and landing aircraft can be summarized as follows: traditional helicopters have low flying speed, short range, and complex rotor system; when adding tilting propellers / tilting rotors, compared with traditional helicop...
