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.

Embodiment Construction

[0030] The specific implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] A miniature flapping wing that can realize large deformation and high control torque generation, such as figure 1 As shown, a flapping wing 1, a fixing device 2 and a direction changing device 3 are included.

[0032] Such as figure 2As shown, the flapping wing includes a flexible membrane 101 , a horizontal beam 102 , an oblique elastic rod 103 and a wing root elastic rod 104 . The flexible membrane 101 is made of polyimide material, which is in the shape of a bionic flapping wing. The leading edge is horizontal, and the trailing edge is a circular arc shape, and the chord length decreases from the wing root to the wing tip; 102 bonding, one side of the wing root is bonded to the wing root elastic rod 104, and the wing root elastic rod 104 is pasted on the horizontal and straight beam 102 at an angle of 100° to 120° wh...

Abstract

The invention discloses a miniature flapping wing that can realize large deformation and high control moment. The range of motion of the flapping wing makes the degree of deformation of the wing membrane and the change of the angle of attack more significant during the front and rear shooting of the flapping wing, thereby greatly increasing the range of variation of the rolling moment and pitching moment, and enhancing the control of the rudder effect. The control effect, anti-disturbance ability and maneuvering flight ability have been greatly improved. In addition, the modular design of the flapping wings also allows the entire two-way hinge device to be decomposed into simple independent units, which is convenient for disassembly and maintenance and saves costs.

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. [...
