SUPERCAVITATING AND VENTILATED PERFORMANCE OF THREE HYDROFOIL SECTIONS,

Abstract

Two-term, 5-term, and flat-faced hydrofoils with AR = 3, rectangular plan form, were tested to determine their supercavitating and ventilated performance. It was found that the 5-term section provides the highest lift-drag ratio for the same lift coefficient. The theoretical prediction agrees well with experimental data at high angles of attack. Means are suggested to hasten the development of leading edge cavitation at low angles of attack and to overcome the oscillating nature of the lift and drag forces in the transition region (between fully wetted and fully cavitating conditions).
