This paper presents results of water tunnel model experiments and analytical predictions for the propeller-induced unsteady hull surface pressures and blade cavitation produced by a high-power destroyer propeller. The experimental results were obtained with a large model propeller run in the proximity of a partial stern representation of a generic combatant ship hull form, and offer a comprehensive picture of the distribution of unsteady pressure amplitudes near the propeller . There is good agreement between calculated and experimental results for the unsteady surface pressure amplitudes. Predicted blade cavitation patterns s how fair agreement only for the leading sheet cavities.
