Numerical analysis and performance comparison of the same series of composite propellers

Composite marine propeller, due to its potential advantage of reduced weight and noise reduction, has increasingly attracted the attention of researchers. In the current work, the performance and efficiency of the 438x series of composite propellers are studied based on the finite element method (FEM) and the computational fluid dynamics method (CFD). The influence of blade skew angle on the hydro-elastic performance, cavitation and efficiency of composite marine propeller are discussed. The performance differences are compared between composites series propellers and metal series propellers. According to the performance characteristics of the same series of composite propellers, a fast and effective design method is proposed.
