FORCE AND MOMENT MEASUREMENTS OF SUPERCAVITATING HYDROFOILS OF FINITE SPAN WITH COMPARISONS TO THEORY

Measurements were made of lift drag, and moment coefficients, and cavity length for aspect ratio 3 and 5 supercavitating hydrofoils of ellipitical planform. These measurements are compared with theoretical predictions obtained from matching asymptotic expansions for large aspect ratio. Good agreement was obtained for lift and drag coefficients for angles of attack from 10 degrees to 15 degrees and for a wide range of cavity lengths. Theoretical moment coefficients were too large indicating the need for lifting surface corrections.
