CALCULATION OF PROPELLER-INDUCED VIBRATORY HULL FORCES, FORCE DISTRIBUTIONS, AND PRESSURES; FREE SURFACE EFFECTS

It is shown how a formula originally developed for calculating the total unsteady propeller-induced forces on a ship hull can be used for calculating the associated hull force distributions and pressures as well. Total vertical forces and the axial distribution of vertical force on a flat plate are calculated using the formula. Two different conditions on the water free-surface are investigated. These conditions correspond to approximations to the exact linearized free-surface condition in the extremes of high and low frequency. The calculations are also performed for circumferentially uniform and nonuniform propeller inflows.
