SYSTEMATIC MODEL EXPERIMENTS ON THE CARGO SHIP FORMS

Abstract

A simple method of drawing ship's lines is explained and it is pointed out that the surface of a ship can be determined by two directrices. Varying the directrices systematically, nine aft-body forms are fixed and they are tested in conjunction with the same fore-body. The resistance of these forms are compared. To obtain informations for designing propellers, the mean annular wakes of these models at the position of propeller are measured and compared.
