Miniature flapping wings capable of realizing large deformation and high control moment generation

Abstract

The invention discloses miniature flapping wings capable of realizing large deformation and high control moment generation. The fixed connection mode of flapping wing root elastic rods and a rack is changed into two-way hinge connection, and the transverse and longitudinal movement range of the flapping wing root elastic rods is increased, so that the wing membrane deformation degree and attack angle change are more obvious in the forward and backward flapping process of the flapping wings, therefore, the change range of the rolling moment and the pitching moment is greatly increased, the control steering effect is enhanced, and the control effect, the disturbance resistance and the maneuvering flight capacity of a flapping-wing aircraft are greatly improved. Besides, the flapping wings are designed in a modular mode so that the whole bidirectional hinge device can be decomposed into simple independent units, disassembly, assembly and maintenance are facilitated, and the cost is saved.

Description

technical field [0001] The invention relates to the field of micro-flapping-wing aircraft, in particular to a micro-flapping-wing design that can realize large deformation and high control torque generation. Background technique [0002] In recent years, with the rapid development of micro-electromechanical technology, computer technology, artificial intelligence and other technologies, and with the continuous progress of aircraft design technology, various types of micro-aircraft are developing more and more rapidly. Compared with fixed-wing and rotary-wing micro-aircraft, micro-orthopting-wing aircraft has higher aerodynamic efficiency at low Reynolds numbers, and a large number of bionic designs are used. At the same time, the aircraft has the advantages of concealment and miniaturization, and has become an important direction for the development of micro air vehicles. At present, micro flapping wing aircraft still face difficulties in efficient and precise control. [...

AI Technical Summary

Problems solved by technology

[0004] The invention aims at the flapping wings of the existing miniature flapping wing aircraft, which can only slightly change the tension of the wing membrane during the wing up and down shooting process by means of the deformation of the wing root bar, so that the aerodynamic control moment generated by the above control action is small, and the control rudder effect is small. As a result, it is difficult to maintain efficient attitude control. A miniature flapping wing that can achieve large deformation and high control torque is proposed.
