A self-contained, rapid, Computer Aided Design (CAD) program for a desk top computer (i.e. HP 9845) was developed for a first cut approximation for the design of a supercavitating propeller blade. This program eliminated the error-prone, tedious interpolation of empirical data graphs by providing approximations and curve fitting techniques to augment existing formulae. The complex Goldstein function and the inexact Prandtl approximation were replaced by a more simple function, the Wilson factor, that maintained the confidence level of the manual calculations.
