Abstract

The invention discloses a dragonfly-like four-wing miniature flapping-wing aircraft. The aircraft comprises a robot body, two front flapping wings, two front wing connecting pieces with connecting rods, two rear flapping wings, two rear wing connecting pieces with connecting rods, a driving gear, a shaft gear, a first-stage gear, two second-stage gears with connecting rods, two third-stage gears with connecting rods, two front ball head connecting rods, two rear ball head connecting rods, two steering engine connecting rods, two steering engines and a direct-current brushless motor. The dragonfly-like miniature flapping-wing aircraft is designed based on bionics, and compared with an existing fixed-wing aircraft and an existing rotor aircraft, the dragonfly-like miniature flapping-wing aircraft is integrally light, high in energy utilization efficiency, suitable for the low-Reynolds-number flight environment and capable of being widely applied to low-speed and high-maneuverability flight scenes.

Description

technical field [0001] The invention relates to a miniature flapping-wing aircraft with four wings imitating a dragonfly. Background technique [0002] The flapping-wing aircraft is a new type of aircraft that imitates the flight of birds or insects. Compared with traditional fixed-wing or rotary-wing aircraft, the power system and control system of the flapping-wing aircraft are integrated, and the flight control is integrated in the flapping system. Has high mechanical efficiency. Through the high-frequency flapping and twisting actions of the flapping-wing wings, the miniature flapping-wing aircraft has high maneuverability. [0003] In terms of volume, the size of insects and birds is much smaller than that of conventional aircraft. When flying, the flapping frequency of wings is high, and the aerodynamic force generated is small but has obvious periodicity. The surrounding flow field is characterized by small scale and rapid change. At present, the research on the fla...
