A method of calculation is presented for the flow characteristics of a two-dimensional supercavitating cascade with finite-length cavities and with an arbitrary pressure distribution. The principle of hydrofoil-airfoil correspondence of the infinite-cavity cascade is utilized. Simplified formulas for the drag and the cavity and foil shapes are derived, and several sample calculations are made. A nonlinear approximation for a thick leading-edge shape is also considered.
