EXPERIMENTAL PERFORMANCE OF TMB SUPERCAVITATING PROPELLERS,

Abstract

In order to evaluate the TMB design method for supercavitating (SC) propellers, and the validity of the theoretically calculated supercavitating design charts, several supercavitating propellers were built and tested in the TMB 24-inch water tunnel. The test results are given. Comparisons between the predicted performance and the test results showed that the predictions are adequate enough to warrant the use of the TMB supercavitating series charts. Parts of the theory used in the design method are inadequate, however, and improvements in the theory can be expected to lead to more accurate predictions. Calculations were performed using nonlinear lift coefficients and cavitating corrections, but only a small improvement was obtained. Finally, it is concluded that a rational lifting surface theory is needed. (Author)
