Hydrodynamic Assessment of Alternative Propulsion Arrangements
Abstract
Non-traditional hydrodynamic propulsion systems such as pods, water jets, surface drives, and vertical axis propellers either inherently provide a steering capability or are sold with the steering element as an integral part. In addition, the appendage drag of these systems varies greatly. Thus the traditional measure of merit, the propulsive coefficient, which is mostly concerned with propeller efficiency and hull-propeller interaction, is not the best assessment of non-traditional propulsion systems.
