Abstract

The invention discloses a miniature dragonfly-like double-flapping-wing aircraft. The miniature dragonfly-like double-flapping-wing aircraft comprises a frame, flapping wings, a gear set, a connecting rod, a brushless motor and a servo motor. A front flapping wing has a free degree for flapping by winding a shaft, a rear flapping wing has two free degrees for flapping by winding the shaft as well as back and forth overturn; Compared with the current fixed wing airplane, the miniature dragonfly-like double-flapping-wing aircraft has high energy utilization efficiency, is adapted to low Reynolds number flow field, is designed based on bionics, and can be widely used for different occasions for Mars detection and military reconnaissance.

Description

technical field [0001] The patent of the invention belongs to the field of aerospace and relates to a miniature flapping-wing aircraft imitating dragonfly wings. Background technique [0002] Micro flapping wing aircraft is a new concept aircraft that imitates the flight of birds or insects. Compared with fixed wings and rotors, flapping wing aircraft integrates ascent, hovering and propulsion into one flapping system, requiring only a small energy loss It can complete long-distance flight, and the fluttering and twisting of the flapping wings in a high-frequency state enables it to obtain unparalleled maneuverability. [0003] The size of insects and birds is much smaller than that of conventional aircraft, the absolute value of the aerodynamic force generated is very small, and the flapping frequency is high, so the flow field around them presents the characteristics of small scale and fast change. The existing two-wing flapping-wing aircraft is mainly used to study the a...
