Performance of a TAP-2 Hydrofoil.

Abstract

This report discusses the measured performance of the TAP-2 hydrofoil, a 'mixed foil' designed to operate fully wetted at takeoff (35 knots) and which, through a change in geometry, can fly fully ventilated at cruise speed (60 knots). At takeoff, TAP-2 has a lift-to-drag ratio of 13 at the design lift coefficient; the corresponding figure for cruise speed is between 7 and 8. Predictive extrapolation to prototype scale is discussed and contrasted with our present understanding of the scaling laws associated with ventilation. (Author)
