Embodiment Construction

[0024] The specific implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] like figure 1 As shown, the present invention imitates the multi-flapping-wing micro-aircraft designed for geese formation and gliding flight, comprising a body 7, a first flapping wing 1, a second flapping wing 2, a third flapping wing 3, a fourth flapping wing 4, The fifth flapping wing 5 and the sixth flapping wing 6.

[0026] The body 7 is formed as a whole, and is a left-right symmetrical structure, which contains a cavity, fixes three pairs of flapping wings and arranges a flapping motion system, a flapping-wing attitude locking mechanism and a flapping-wing motion control system. The clapping motion system includes a motor, a gear reduction mechanism and a link mechanism. The motor is fixed inside the body, and the high-speed output of the motor is decelerated by the gear reduction mechanism. The deceleration mec...

Abstract

The invention discloses a multi-flapping-wing micro air vehicle designed by imitating wild goose array formation and gliding flight. The multi-flapping-wing micro air vehicle is in a six-flapping-wing layout form and is composed of a vehicle body and three pairs of flapping wings, the three pairs of flapping wings are in bilateral symmetry and are arranged on the two sides of the vehicle body in a stepped mode, and wing tips of each pair of front flapping wings are flush with the half-span positions of the adjacent rear flapping wings. Wild goose array formation and gliding flight are simulated, and when the aircraft flies at high altitude and high speed, the flapping wing attack angle is fixed for gliding flight; and when high lift force and high thrust are needed, the flapping wings flap obliquely in the same phase to generate lift force and thrust. According to the multi-flapping-wing micro air vehicle imitating wild goose array formation and gliding flight design, the interference effect of wingtip vortexes generated by the front flapping wings on the rear flapping wings is effectively utilized, and the problems that a traditional flapping-wing air vehicle is insufficient in lifting force and low in aerodynamic efficiency are solved.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a micro-aircraft with multiple flapping wings designed to imitate formation and gliding flight of wild geese. 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. 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. [0003] At the same time, with people's 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 biological flight have begun to appear. Although mos...
