The propulsive efficiency of flexible flapping-wing is different with its rigid situation. This problem is investigated by numerical simulation method, which is developed and validated in our previous research. The effects of flight velocity and flapping frequency are simulated. The results show that the deformation can change the propulsive efficiency notably.
