Abstract:

A lifting-surface theory and numerical procedure for designing supercavitating propellers are presented. Both a subcavitating and a supercavitating propeller are represented by vortex and source distributions. Unlike the subcavitating propeller, however, source strengths for a supercavitating propeller are related to cavity thickness, which is not known without examination, and have to be obtained by solving related integral equations. Numerical computations were also used to design two additional supercavitating propellers which were built and tested. The design predictions are compared to the experimental data, both for blade cavity height and performance characteristics, and good correlation is obtained.
