PRELIMINARY DESIGN OF HYDROFOIL CROSS SECTIONS AS A FUNCTION OF CAVITATION NUMBER, LIFT, AND STRENGTH

A set of graphs and equations is developed for quickly determining the minimum-drag form of noncavitating and supercavitating hydrofoils designed for high Reynolds numbers where the boundary layer is fully turbulent. A single classification parameter is derived which simplifies design selection. The results are applicable to the design of propellers, struts, lifting surfaces, and fins for both submerged vehicles and surface craft. It is shown that hydrofoil cross sections can be classified into six basic types of design forms, five of which are cavitating.
