The design of a model hydrofoil system for operation from 35 to 80 knots is discussed. Pertinent features include a fully wetted flow regime at takeoff and low-speed cruise, fully cavitating operation at high-speed cruise (60 knots), and the use of a spoiler to achieve a burst speed of 80 knots. A propulsion system is not included on the model; however problems of force control and flap location have been accounted for. The model promises a significantly improved lift-to-drag ratio at takeoff over previous high-speed hydrofoil models. (Author)
