It is assumed that the hydrofoils Are operating at zero cavitation number and that the Froude number - based on depth - is very large. The general expressions are used to derive the lift, cavity drag and shape of hydrofoils composed of 2-, 3-, and 5-term and constant pressure camber configurations, combined with angle of attack and quasi-parabolic thickness and designed for operation at specific depths. Examples of numerical results are given and the effect of foil strength is discussed and evaluated.Read More
