Predicition of marine propeller loading noise

Propeller loading noise is the main part of the propeller noise. Based on the unsteady lifting surface method and the Goldstein's acoustic analogy Theory, we studied the characteristics of the propeller loading noise. The introduction of the method and some theoretical analysis results are given in this paper. Numerical analysis of the propeller loading noise was also done in this paper, and some useful results which are practical for engineering are presented in this papre.
