Abstract

The invention discloses an electromagnetically-driven flapping wing type micro aircraft based on flexible hinges, which comprises chest cavities, cylindrical permanent magnets, a spiral coil, wings, a tergum and flexurally-deformed flexible hinges, wherein the two flexible hinges are passively twisted; the pair of wings is symmetrically mounted on both ends of the tergum; the flexible hinges are sandwiched between the two chest cavities to form a sandwich structure, the tergum is fixed on the flexible hinge, and both ends of the tergum are symmetrically positioned in free regions of the chest cavities; the spiral coil is fixedly mounted in the central position of the chest cavities; and the permanent magnet is fixed in the center of the tergum. Though the machining based on an MEMS (Micro Electronic Mechanical System) process, the invention realizes the flapping wing type micro aircraft of which the wingspan is smaller than 3cm, and driving force can be obtained through the interaction of the energized spiral coil and a magnetic field between the permanent magnets. Besides, the invention has the advantages of very simple structure, small input voltage and large output force, is convenient and flexible to control, and is easy to realize portable operation.

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 based on a flexible hinge. Background technique [0002] The flapping-wing micro-aircraft is a micro-aircraft that imitates the flight of birds or insects. 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 realization of micro-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. The flapping-wing micro-aircraft has maneuverability and aerodynamic performance unmatched by general aviation aircraft. It has the adv...
