Problems solved by technology

[0004] At present, in the imitation dragonfly multi-wing flapping wing aircraft, due to the small overall size and weight of the aircraft, and the high flapping frequency of the flapping wings, the traditional motor plus crank rocker or rack and pinion transmission mechanism has complex structure and low motion accuracy. Low, poor reliability, difficult to meet the design requirements of aircraft
However, limited by the constraints of materials, micro-electromechanical, and processing and manufacturing technologies, it is difficult for the new drive method to be used in an actual engineered flapping wing aircraft.

Abstract

The invention provides a hovering multi-wing bionic aircraft which comprises an integral support, four direct-drive transmission mechanisms are arranged on the integral support, and a flapping wing is mounted on each direct-drive transmission mechanism; each direct-drive transmission mechanism is connected to a flight control driving system; on the basis of ensuring the transmission power and the torque requirement, the transmission system structure is greatly simplified, and the overall transmission efficiency and the mechanical reliability of the aircraft are improved; through reasonable spatial distribution layout, aerodynamic interference between the front wing and the rear wing is effectively reduced, and the overall aerodynamic performance of the aircraft is improved.

Description

technical field [0001] The invention belongs to the technical field of bionic flapping-wing unmanned aircraft, and in particular relates to a hoverable multi-wing bionic aircraft. Background technique [0002] The micro flapping wing aircraft is an unmanned aerial vehicle that imitates the flight of birds and insects. Because of its unique bionic shape and flight characteristics, it has high maneuverability, flexibility and concealment, so it is used in low-altitude reconnaissance and urban combat. Compared with fixed-wing and rotary-wing micro-aircraft, it has more advantages in missions such as electronic interference, nuclear, biological and chemical detection, geographical survey, natural disaster monitoring and support, environmental pollution monitoring and border patrol, and has a wide range of applications in national defense, military and civilian use. Application prospects. Dragonflies have excellent flight capabilities, with an average flight speed of about 1-5m / ...
