Abstract
Lifting-line theory for calculating the characteristics of a supercavitating propeller is derived. The theory makes use of induction factors and is applicable for propellers of normal supercavitating geometry and for non-zero cavitation numbers.
By comparison with model tests correction factors are developed to improve the numerical results and to correct for the the shortcomings of the lifting-line theory.
Results are shown from calculations in which the propeller data are varied systematically thus making a small propeller series.
