| Abstract: | The hydrodynamic performance of a marine propeller was predicted based on the lifting surface method.The strength of its blades was analyzed by FEM.The results showed that the accuracy can meet the engineering requirements.Then the hydrodynamic performance and blade strength of an aluminum alloy propeller were analyzed in these two methods.The weight of aluminum alloy propeller loses up to 158.3kg,59% than using copper alloy in the condition that it well satisfies the requirements of design. |
