Abstract:

A program is currently being pursued to estimate the relative degree of sound radiation from various pulsating sources on a submarine hull. This particular study was initiated to compute the approximate effect that the pulsating propeller force could have on hulls of various dimensions. It is the purpose of this study to obtain approximate formulas which can be used to assess the relative importance of the physical parameters without the use of complicated digital programs.
