The resulting integral equations are solved by numerical techniques on a high-speed digital computor to predict steady and oscillatory loads. The following cases are discussed: thin non-planar hydrofoils at infinite Froude number, the effect of gravity waves on the forces on an oscillating hydrofoil near the free surface, supercavitating hydrofoils of finite span in steady and oscillatory motion. Numerical results for lift and moment are presented and comparison with experiment is made whenever possible. Results of these calculations indicate that this numerical solution is a very practical and efficient way to obtain accurate prediction of unsteady loads for flutter calculations.Read More
