Abstract:

This report presents the results of an investigation into the calm water resistance characteristics of a series of transom sterned ships. Five transom shapes and their corresponding after-bodies were designed to examine the effect of draft and beam at the transom on ship resistance. There were two draft and two variations from a common baseline hull. The forebody was held constant for all five designs. Each of the variations represented typical surface combatants of the frigatedestroyer family. Models were built of each hull and still water resistance tests were run in the 380 foot towing tank at the U.S. Naval Academys Hydromechanics Laboratory. Analytical studies of each hull were performed using existing potential flow code algorithms. Keywords Ship resistance, Ship hulls, Naval architecture, Hydrodynamics.
