TAKEOFF EXPERIMENTS OF A HIGH SPEED HYDROFOIL SYSTEM (TAP-2)

As part of an effort to develop a data base and design criterion for high speed struts and foils, experiments were conducted to evaluate the TAP-2 foil performance for a range of speeds, including the design takeoff speed of 35 knots. The T-foil system, designated as TAP-2, was designed to operate fully wetted at takeoff and as a supercavitating foil at a 60 knot cruise speed. Experiments were conducted at 30, 35, 40, 45, and 50 knots at various depth-to-chord ratios and at a range of foil incidence angles.
