Effects of stacking sequences on the hydroelastic behavior of composite propeller blades

摘要

Afinite element method coupled with analysis of a non-cavitating lifting surface was used to assess the performance of a composite marine propeller, including thrust, torque, efficiency coefficients and deflections. An MAU 3-60 propeller was analyzed with different stacking sequence of T300/1076E. The hydroelastic behavior of the propeller with balanced and unbalanced stacking sequences were investigated and discussed. Stacking sequences effects have been shown to influence the performance of composite propeller in region of low advanced coefficient, J.
