For marine propellers with highly skewed profile or composite material, or working at low speed heavy load conditions, the effect of Fluid Structure Interaction (FSI) should be considered in propeller design to avoid mismatching of vessel-engine-propeller and misestimating of full scale vessel propulsion performance. Based on propeller circulatory flow theory, propeller FSI algorithm and successive approximation method, a propeller design method with consideration of hydroelastic effect was proposed, and the influences of renewal mode of hydrodynamic force in FSI and pre-design relax factor on design result were discussed. Finally, a highly skewed propeller and two composite material propellers were designed by platform developed to further describe the necessity of considering hydroelastic effect in design of flexible propeller, which also testified the validity of platform. The designed platform could provide a foundation for further study on optimization design of composite propeller.
