HEAVING MOTION OF VENTILATED TRAPEZOIDAL HYDROFOILS

The calculations are carried out using a numerical method of solution in linearized supercavitating lifting surface theory. The hydrofoil is assumed to bear an ambiant pressure cavity on its whole upper surface, extending to downstream infinity. Attention is being paid especially to the effect of the planform shape as schematized by the aspect ratio, the taper ratio and the sweepback on the unsteady lift, drag and pitching moment.
