This paper describes the design and analysis of a new propulsion technology, which is inspired by the motion feature of the bird’s feathers. Both the structural models and its flapping wings of the bioinspired propulsion are established. The dynamic equation and threedimensional NavierStokes equations are solved to acquire motion features and mechanical properties. Then, the aerodynamic performance of the wings for the propulsion which reciprocates at a constant speed is achieved though the analysis of the flow field characteristics. The flow distributions of the modular hingetype wings in some typical moments are studied.  The lift coefficients, the angle between blades and yOz plane, the angular velocity of the blades for different exercise frequency are further discussed. The results indicate that this type of propulsion can provide an efficient propelling force when wings are flapping at a low frequency by reciprocating in long travel. The average lift coefficient in a moving cycle would keep above 3.0 when the frequency is 2Hz.
