Multi-flapping-wing aircraft and flying control method thereof

Abstract

The invention provides a multi-flapping-wing aircraft and a flying control method thereof. The multi-flapping-wing aircraft comprises a rack and four independent flapping wing mechanisms which are mounted on the rack and have the same structures, wherein a landing gear is arranged below the rack. When the flapping-wing aircraft is parked on a horizontal plane, the bottom surface of the rack is parallel to the horizontal plane; the four independent flapping wing mechanisms are distributed at four corners of the rack in a leftward-rightward symmetric and forward-backward symmetric manner; and each flapping wing mechanism comprises a wing, a mover, a similarly I-shaped soft iron core, a coil, an edge-grooved wheel and a rubber ring. Swing motors are used for directly driving the wings to swing; no transmission mechanisms are arranged between the swing motors and the wings; and by changing the time for applying voltage to two electrodes of each swing motor, flying of the flapping-wing aircraft is controlled, so that the wing swinging frequency can be increased favorably, and the lift force is enhanced. The flapping wing mechanisms are high in swinging strength, long in service life and low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a multi-wing aircraft and a flight control method thereof. Background technique [0002] In nature, the flapping flight of some birds and insects can achieve hovering, which has high maneuverability and low energy consumption. Man-made flapping-wing aircraft has very broad application prospects in military and civilian applications. The United States has developed the "Hummingbird" miniature flapping-wing aircraft, which has made a breakthrough in the artificial flapping-wing aircraft. [0003] In the prior art, the artificial flapping wing aircraft has the following problems: [0004] 1. A rotating motor is used to drive the wing to swing. A transmission mechanism is needed between the rotating motor and the wing to convert the rotation of the rotating motor into the swing of the wing, which increases the weight, energy consumption and noise of the flapper. [0005] 2. Only by swingin...

Problems solved by technology

[0005] 2. Only by swinging two wings to control the flight of the flapping wing aircraft, the flapping wing mechanism is complicated, it is difficult to increase the swing frequency of the wings, and the lift is small
