PERFORMANCE OF WAKE-ADAPTED PROPELLERS IN OPEN WATER AND PROPULSION CONDITIONS AS DETERMINED BY THEORY AND EXPERIMENT

Abstract

Important considerations and concepts concerned with determining propeller performance in open water and propulsion (behind-body) conditions are discussed. Two wake-adapted propellers were designed by the Eckhardt-Morgan method using Lerbs' theory of moderately loaded propellers. Performance of these propellers in open-water and wake-adapted conditions was calculated by the Burrill method. For examples of a submerged body of revolution and a single- screw surface ship, relative rotative efficiencies, as obtained by theory and model experiment, are shown to be in good agreement.
