Abstract

In order to predict the propeller noise under different phase angle combinations, a computational fluid dynamics approach incorporating the FW-H equation was used to calculate the acoustic field characteristics of the propeller. The propeller signatures were calculated directly using Fourier transforms. The results indicate that the noise prediction model constructed based on propeller signatures theory has an error of within 1% for the first three orders of discrete noise and within 8% for the fourth and fifth orders of discrete noise. Compared to traditional identification methods, the prediction accuracy has improved by 30% to 50%.
