A flapping rotor with an angle of attack control device

Abstract

The invention discloses a flapping rotor with an angle of attack control device, which belongs to the technical field of micro-aircraft. Including flapping rotor, angle of attack control device and limit device; flapping rotor includes main beam, short beam, inclined beam and wing membrane; Stopper and angle of attack controller; a groove is made on the angle of attack controller, and the baffle moves up and down in the groove; the stopper is used to control the range of motion of the baffle. The other includes deformation sheets and limit beams. By changing the thickness of the deformation sheets or adjusting the distance between the connection point of the short beam and the inclined beam and the main beam, the angle of attack of the airfoil when the flapping rotor is shot up is controlled. The limit beam is used to Limit the deformation of the flapping rotor when the flapping rotor is down; by controlling the angle of attack of the flapping rotor during the flapping process, on the basis of maintaining the positive lift, the negative lift is effectively reduced, and the average lift of the micro flapping rotor aircraft is improved. The energy utilization rate of the aircraft is improved.

Description

technical field

[0001] The invention relates to the field of micro-aircraft, in particular to a flapping rotor with an angle of attack control device. Background technique

[0002] Since the 1990s, with the continuous improvement of traditional aircraft design technology, people have continued to explore and understand the mechanism of animal flight and swimming, and with the rapid development of microelectronics technology, the field of micro air vehicle design It is developing more and more rapidly, and has broad application prospects in national security and national economic construction. It is applied to tasks such as reconnaissance, communication, exploration, and assistance in rescue under complex environmental conditions.
