Abstract

Bionic flapping wing MAV has excellent aerodynamic performance and a wide application potential, which is usually equipped with a pair of flexible wings. Flexible flapping wing will deform in the flight for the pressure of aerodynamic and inertial forces generated in flapping movements. The propulsive efficiency of flexible flapping-wing is different with its rigid situation. At the meantime, the different flight conditions or parameters also affect the propulsive efficiency. This problem is investigated by numerical simulation method in this paper. The effects of flight velocity and flapping frequency are simulated. The results are given both in flexible and rigid flapping wings for comparison. The results show that the deformation can change the propulsive efficiency notably. The propulsive efficiency of flexible flapping wing is far larger than that of rigid wing. There will be a best parameters combination to make a highest propulsive efficiency for the flexible wings. The flapping wing air vehicles fly in this state will have long endurance or range.
