Flapping-rotating wing with attack angle control device

Abstract

The invention discloses a flapping-rotating wing with an attack angle control device, and belongs to the technical field of micro aerial vehicles. The flapping-rotating wing comprises a flapping-rotating wing body, the attack angle control device and a limiting device, wherein the flapping-rotating wing body comprises a main beam, a short beam, an inclined beam and a wing membrane; the attack angle control device and the limiting device act commonly and comprise two modes, one mode is that the attack angle control device and the limiting device comprise a baffle plate, a limiter and an attack angle controller, a groove is formed in the attack angle controller, the baffle plate moves up and down in the groove, and the limiter is used for controlling the movement range of the baffle plate; the other mode is that the attack angle control device and the limiting device comprise a deform sheet and a limiting girder, the thickness of the deform sheet is changed or the distance from the connecting point of the short beam and the inclined beam to the main beam is adjusted to control the wing section attack angle when the flapping-rotating wing body flaps upwards, and the limiting girder is used for limiting the deformation of the flapping-rotating wing when the flapping-rotating wing flaps downwards; the attack angle of the flapping-rotating wing during flapping is controlled, while positive lifting force is maintained, negative lifting force is effectively reduced, and thus, average lifting force of the micro aerial vehicle with the flapping-rotating wing is increased and the energy utilization rate of the aerial vehicle is increased.

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. [0003] Publication number is the patent application of CN 101492093: " flapping rotor design method and the miniature flapping rotor aircraft designed by this method " discloses miniature flapping rotor aircraft. The lift of the micro flapping ro...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the average lift of the flapping rotor is small and the energy utilization rate is low due to the negative lift generated by the flapping rotor, and a flapping rotor with an angle of attack control device is proposed.
