Effects of blade skew on the hydrodynamic and deformation performance of propellers

  • During the operation of submarine propellers, the fluid mechanical pressure load on the blades could result in a structural load on the component, which in turn causes deformation of the blade. In this pa-per, the structural response is analyzed with the finite element method, and the coupling simulation is ac-complished by using ACT_Transient FSI in ANSYS Workbench. The geometries of the propeller DTMB 4381~4383 are then taken as the research objects, where the deformation characteristic and hydrodynamic performance of these propellers are studied. The results show that the max blade displacement worsens with the increase of skew angles, and the vibration of the blade decreases simultaneously.
