Lift force and rolling torque control method for bionic micro flapping-wing air vehicle

Abstract

The invention discloses a lift force and rolling moment control method for a bionic micro flapping-wing aircraft, and aims to solve the problems of generation and control of lift force and rolling moment of the aircraft. When the aircraft needs to generate lift force and rolling torque, the deflection angles of wing rods at the front edges of flapping wings on the two sides around wing roots are controlled through steering engines, the flapping plane positions of the wings and the tightness degree of wing membranes are changed, then the lifting force of the wings is changed, the left side and the right side generate different lift force, and expected rolling torque is obtained; the rolling control of the bionic micro flapping-wing air vehicle is realized. According to the lift force and rolling control method, wings of the bionic micro flapping-wing aircraft are directly operated, a control mechanism is easy to implement, large deformation of a wing membrane can be caused by controlling movement of a leading edge wing rod, large control torque is generated, and in addition, the control mode that the two wings are controlled through the two steering engines respectively is adopted, so that the lift force and rolling speed is greatly improved. And the generation and control precision of the lift force and the rolling moment is also obviously improved.

Description

Technical field [0001] The present invention relates to the field of micro aircraft, in particular a bionic micro-flapping aircraft lift and a rolling moment control method. Background technique [0002] The micro aircraft is a new type of aircraft developed mid-1990s. In the past two decades, with the continuous improvement of traditional aircraft design technology and the continuous maturity of microelectronics technology, micro aircraft was proposed and rapidly developed.
