Problems solved by technology

[0005] The present invention aims at flapping both wings in the same direction for the existing miniature flapping rotor aircraft, resulting in extremely large wing lift and transient energy consumption during down-shooting, and very little lift and transient energy consumption during up-shooting. Due to the huge difference in transient energy consumption, large fluctuations in system lift, and low overall energy utilization, a miniature flapping rotor aircraft with differential flapping wings was proposed.

Embodiment Construction

[0025] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0026] The present invention is a miniature flapping rotor aircraft with differential flapping of two wings. The left and right wings are flapped differentially, and the flapping difference is about 180 degrees, that is, when one wing flaps downwards, the other flaps upwards. When the average lift is kept constant during flapping of the wings at the same frequency, the lift is more uniform throughout the flapping cycle, and the maximum output power of the motor only needs to be slightly greater than the maximum power of a single wing when flapping down, which effectively reduces a During the flapping process, the maximum power consumption of the wing and the transient lift fluctuation can significantly improve the energy utilization efficiency of the aircraft.

Abstract

The invention discloses a micro-flapping rotor aircraft with differential flapping of two wings, and relates to the field of micro-aircraft. The aircraft includes a wing, a transmission mechanism, a power unit and a base; the power unit and the transmission mechanism are fixed on the base, and a wing is respectively fixed at both ends of the transmission mechanism; during work, the micro-motor in the power unit provides power to drive the transmission mechanism The inner rod of the wing lifts up and down, causing the two wing connecting rods to move in opposite directions at the same time, driving a pair of symmetrically arranged wings to move down and up alternately to achieve differential flapping. The present invention ensures that the average lift remains unchanged during the flapping of the wings at the same frequency, the transient lift fluctuations of the wings are significantly reduced, the lift is more uniform throughout the flapping cycle, and the requirements for the output power of the motor are effectively reduced, significantly Improve energy efficiency.

Description
