Effects of Propulsion Pod Longitudinal Location on the Resistance Characteristics of a Ship.

Abstract

A series of resistance and longitudinal wavecut experiments were performed with Model 5359-5B, representing a DD963 hull at the David Taylor Naval Ship R and D Center (DTNSRDC) to investigate the change in resistance caused by varying the longitudinal position of a single propulsion pod. Sharma's method of bulb optimization was used in an attempt to find the optimum longitudinal pod position. The experimental results indicate that the pod could be located between 80 to 90 percent of the ship length wth virtually no change in total resistance. It was found that Sharmas method could not be used to determine the optimum pod location. (Author)
