Experiments were conducted at the High Speed Water Tunnel of the California Institute of Technology for measuring the flow characteristics of a single foil over a full range of cavitation numbers. The blade profile shape used was taken after the cross-section profile of a supercavitating propeller designed for an actual high speed hydrofoil boat. It was discovered in the experiments that for higher incidence angles than 2 degrees, the cavity LAB and sometimes double cavities appeared. This fact, which was never considered in the design procedure nor in the off-design prediction theory, might have caused an erroneous prediction for the thrust coefficient and efficiency of this supercavitating propeller. Three new nonlinear cavity flow theories have been developed, one for the supercavitating (S/C) regime and two for the partially cavitating (P/C) regime. The results of these theories compared favorably with the experimental data, but the accuracy degraded as the cavity length became close to the chord length.
