摘要：This paper aims to predict the hydrodynamic characteristics and structural analysis of the marine propeller under pressure hydrodynamic loading. Because of the loading on the propeller blade, it goes under significant deformation that may affect the hydrodynamic performance of the propeller. Thus, the blade deformation of a propeller due to fluid pressure should be analyzed, considering hydro-elastic analysis. The propeller was made of anisotropic composite materials, and the geometry of the propeller is for one skew angle. First, the hydrodynamic pressure loading is obtained by FVM and then the deformation of the blade due to this pressure was calculated. Next, the pressure load for deformed propeller is achieved; it is again repeated to obtain the new deformed propeller. This procedure is repeated to converge the thrust, torque and efficiency. We present all results of the pressure distribution, hydrodynamic characteristics, stress and deformation of the propeller.
