Description

technical field [0001] The invention relates to the technical field of flapping-wing aircraft. Background technique [0002] Compared with traditional fixed-wing and rotary-wing unmanned aerial vehicles, micro-bionic flapping-wing aircraft can accomplish many tasks that other aircraft cannot perform due to its small size, light weight, low cost, strong concealment and good maneuverability, such as Low-altitude reconnaissance, urban combat, electronic interference, nuclear, biological and chemical detection, geographic survey, natural disaster monitoring and support, environmental pollution monitoring, and border patrol have very important and extensive application prospects in the civil and national defense fields. With the development of technologies such as bionics, unsteady aerodynamics, micro-electromechanical systems, and flexible materials, it is possible to develop smaller, lighter, and intelligent flapping-wing aircraft. The miniature flapping wing aircraft needs to...

AI Technical Summary

Problems solved by technology

The miniature flapping wing aircraft needs to convert the turnover motion output by the motor into the reciprocating motion of the output end. At present, the connecting rod mechanism and gear mechanism used in the mainstream are complex in structure and restricted by the mechanical manufacturing capacity. In order to ensure the transmission performance, the transmission system has a large volume and weight. , restricting the miniaturization development of flapping wing aircraft
