Analysis suggests high-speed ducted propeller has definite potential for propulsion of high-speed marine craft; it can operate efficiently within propulsor performance gap and in region now proprietary to supercavitating propeller; structural aspects of subcavitating rotor are satisfactory for transmitting large amounts of power to water, and cavitating shroud is not expected to prove difficult structural problem; as examples, performance of two types of high-speed ducted propellers is analyzed for two bodies of revolution at depth of 10 ft and at velocities of 50 and 70 knots, respectively, and compared with supercavitating propellers.
