Micro-miniature multi-wing bionic flapping wing air vehicle

Abstract

The invention discloses a micro-miniature multi-wing bionic flapping wing air vehicle and relates to the field of miniature air vehicles. The micro-miniature multi-wing bionic flapping wing air vehicle particularly comprises a chassis, four swing arms, a motor, two gears a, two gears b, a gear c, four connecting rods and four flapping wings. The motor is fixed at the center of the chassis; the gear c is mounted on an output shaft of the motor and engaged with the two gears b simultaneously; each gear b is engaged with the corresponding gear a; one ends of every two connecting rods are hinged together through the corresponding gear a, and the other end of each connecting rod is fixedly connected with the corresponding swing arm; meanwhile, the other end of each swing arm is fixedly connected with the corresponding flapping swing; and the swing arms drive the flapping swings to achieve low-frequency reciprocating flapping and produce aerodynamic lifting force in the vertical direction. The gears and a connecting rod mechanism are used to conduct transmission, manufacturing is simple, and higher design precision is easily obtained; and compared with a single pair flapping wing air vehicle, the effect among the multiple flapping wings can increase the lifting force, the high lifting force mechanism of insects is fully utilized, and higher efficiency is achieved.

Description

technical field [0001] The invention relates to the field of micro-aircraft, in particular to a miniature multi-wing bionic flapping-wing aircraft. Background technique [0002] Since the 1990s, with the continuous maturity of traditional aircraft design technology and the great progress of microelectronics technology, micro air vehicles have been proposed and developed rapidly. [0003] Due to the characteristics of small size, light weight and strong maneuverability, micro air vehicles have broad application prospects in national security and national economic construction, and are suitable for investigation, exploration and rescue assistance in complex environments. [0004] At the same time, with the continuous exploration of natural biological flight, bionic design has been more and more applied to the field of micro-aircraft, and flapping-wing micro-aircraft that imitate the flight of insects have begun to appear. [0005] Most of the mechanism designs of the existing...
