Abstract
An empirical prediction model of broadband noise for marine propellers is proposed. The model is composed of two components. The first component is the empirical prediction of the frequency domain broadband noise based on a wellestablished lifting surface algorithm providing accurate prediction of the cavitation pattern on the propeller. The second component is the modulation of the noise in the time domain. The two components of the model applied in sequence generate an output yielding a realistic propeller spectrum and audio signature. The propeller noise developed in this study, with the addition of other sources such as machinery and natural noise, is used to drive the input of a submarine sonar simulator for training purposes.
