The steady lifting surface theory with a free-surface
Abstract
A method to solve the unsteady lifting surface problem is applied to steady surfaces with a free-surface. The local lifting coefficient appears as a solution to an integral equation of the first kind whose kernel, deduced from the Havelock source potential, is expanded in a Fourier series, with respect to the azimuth angle. Numerical applications such as the calculation of the lift and drag of a lifting wing, and hydrodynamic pressures in the case of turn of a ship are given.
