A STUDY ON LOADING NOISE OF NON-CAVITATING MARINE PROPELLER

In this paper, the far field noise from a propeller in unsteady loading is derived in the frequency domain. Unsteady lifting surface theory is used to analyze the hydrodynamics of the propeller which is rotating in non-uniform flow. A program is coded which can be used to predict the propeller loading noise. Several calculation samples are given to show the characteristics of the propeller loading noise, the effect of wake and geometries of propeller on noise are also studies.
