20. ABSTRACT (Continue on reverse side If necessary and Identify by block number) 



A lifting-surface theory and numerical procedure for designing super- 

 cavitating 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
