A HIGH-SPEED HYDROFOIL STRUT AND FOIL STUDY

A program to establish a technology base for the design of high-speed struts and foils is being undertaken at the center. The initial program rationale is described, which then leads into a variety of detailed analytical and experimental studies of the characteristics of supercavitating (super-ventilating) and streamlined foils, and base-vented and streamlined struts. Preliminary experimental results on struts and foils in calm water and in waves in towing tanks with carriage speeds up to 50 knots are discussed. Experimental systems are being designed to further investigate the effects of twist, aspect ratio, end plates, nose radius, strut ventilation and flutter, and forced ventilation on cavity control.
