ENGINE PROPULSION MATCHING FOR HIGH-SPEED CRAFT

An investigation was made utilizing current literature to determine the performance of a supercavitating vs conventional propeller in relation to hydrofoil craft, and a preliminary choice of propeller diameter and pitch ratio has been made from published series and experimental work. It is shown that the supercavitating propeller already documented fulfills the requirements of highspeed craft at speeds exceeding 100 knots, whereas at speeds greater than 60 knots the conventional propeller fails. This paper also shows that supercavitating sections have good drag-to-lift ratios when the propeller is driven at high rotative speeds. Mention is made of the successful application of light weight gas turbines to marine use.
