TEST OF TRANSOM STERNS ON DESTROYERS.
Abstract
A series of nine 20-ft. models of destroyers was made in which the bows were identical, the dimensions, including displacement, were constant, and the stern load water lines were practically alike. The models differed by variations in the immersion of their transom sterns and in the shape of their buttock lines. The models were towed for resistance at the designed trim and at other conditions of trim and the curves of resistance plotted on speed. The resistances of the models at selected speeds were plotted on variations in transom immersion and shape of sectional area curves. Contour curves of resistance were used to prepare diagrams showing the influence of the variations on resistance. (Author)
