Dual Electromagnetic Drive Micro-flapping Wing Aircraft

Abstract

The invention provides a double electromagnet driving micro flapping wing aircraft which comprises a driving mechanism, a transmission mechanism and wing mechanisms, wherein the driving mechanism consisting of a permanent magnet and two groups of coils drives the connecting rod type transmission mechanism connected by two sets of flexible hinges; the wing mechanisms are installed and fixed on both sides of the transmission mechanism through dovetail grooves, and flap happens along with rotation of a connecting rod at the output end of the transmission mechanism so as to generate lift required by motion of the aircraft. The aircraft provided by the invention has two groups of coils which respectively drive the two wings, and various turning movements and multi-directional linear flight of the aircraft can be realized by respectively adjusting the flapping rule of the two wings.

Description

technical field [0001] The invention relates to the technical field of micro-aircraft, in particular to a dual-electromagnetic-driven micro-flapping-wing aircraft based on a flexible link mechanism. Background technique [0002] Micro-flapping-wing aircraft is a micro-aircraft that is different from fixed-wing and rotary-wing aircraft, and instead imitates birds or insects and uses complex movements of wings to achieve flight. With the development of science and technology in recent years, Micro Aircraft (MAV) is becoming a research hotspot in the scientific and technological circles. In particular, the development of MEMS technology provides the possibility for the processing and manufacturing of small-sized aircraft. 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.
