TECHNIQUES FOR ESTIMATING VIBRATORY FORCES GENERATED BY PROPELLERS

This Bulletin is a condensation of available practical information on the various aspects of ship propeller forces and propeller-induced hull forces arising from the spatially non-uniform flows to which almost all ship propellers are subjected. The work embraces brief physical descriptions of the manner in which blade frequency pressures are generated by propellers; the attending induced pressures on nearby structures to produce hull forces; the forces on the propeller itself and the blade- bending moment and a distillation of experimental results from model tests and full-scale measurements which reveal the dominant effects of certain parameters as currently exhibited.
