A Validation Study of the Mixed Foil Concept for High Speed Hydrofoils.
Abstract
A hydrodynamic validation study of the concept of the mixed foil has been carried out. A mixed foil is a streamlined hydrofoil equipped with a flap or other device which, above a certain speed, can be activated so as to change the flow around the foil into a supercavitating flow. At takeoff and at moderate speeds, a mixed foil is operated as a subcavitating foil; at high speeds, it is operated as a supercavitating foil. During high speed operations, a reduction in the wetted planform area of a mixed foil is proposed. Two hydrofoils which have as their sections plano-convex foils of thickness to chord ratios of 5% and 6% are used for the study.
