Description

technical field [0001] The invention relates to a device in the technical field of micro-aircraft, in particular to an electromagnetic-driven flapping-wing micro-aircraft. Background technique [0002] The flapping-wing micro-aircraft is a micro-aircraft that imitates the flight of birds or insects. In recent years, with the development of cutting-edge technologies such as military and MEMS, the use of winged micro-aircraft (FMAV) has gradually become a research hotspot in the scientific and technological circles. Micro air vehicle is a new type of aircraft developed in the 1990s. The U.S. Defense Advanced Research Projects Agency proposed the basic indicators of micro-aircraft: the size of the aircraft is less than 15cm, the weight is between 10g and 100g, the flight time is 20-60min, and the flight speed is 25-70km / h. Micro air vehicles have the advantages of small size, light weight, good maneuverability and aerodynamic performance, and have very broad application prosp...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the above-mentioned deficiencies in the prior art, and provides an electromagnetically driven flapping-wing micro-aircraft, which realizes a flapping-wing micro-aircraft with a wingspan of less than 3 cm through MEMS processing, and solves the problem of a large required voltage caused by the piezoelectric ceramic drive. It is difficult to carry power by itself, and the passive rotation of the wings is small. The electromagnetic driver obtains the driving force by using the current-carrying conductor to be stressed in the magnetic field. It is directly driven by the electromagnetic force. It has a simple structure, convenient and flexible control, and a large output force.
