ACOUSTIC PERFORMANCE OF THE HIGHLY SKEWED PROPELLER OF A RO-RO CONTAINER SHIP
A description is given of experiments that were performed on board a ro/ro ship to determine the acoustic performance of a highly skewed propeller. The main objective was to ascertain the acoustic source strength and frequency spectrum of the fluctuating volume of propeller cavitation. It was found that the substitution of a highly skewed propeller reduced the acoustic source strength of the propeller cavitation. This lower source strength leads to a substantial reduction of the low frequency components of hull pressures and hull plate vibrations. A corresponding reduction of vibrations in the afterbody of the ship and of noise in accommodation and work spaces is suggested by the data.
