EXPERIMENTAL STUDY OF HIGH SPEED HYDROFOILS, VOLUME 2, PART 4

Abstract

The test program was conducted to measure the hydrodynamic characteristics of a series of transcavitating and supercavitating hydrofoil models with various planforms and sections to provide a design procedure to predict hydrodynamic characteristics for this type hydrofoil. Twenty hydrofoil models were tested at three depths and at a sufficient number of speeds and angles of attack to fully define their hydrodynamic characteristics. Lift, drag, pitching moment, and strut base pressure were measured for all models, and cavity pressure and foil pressure were measured for the supercavitating models. Classic supercavitating hydrofoil theory is shown to predict test results with an accuracy adequate for design if a modified value for the cross-flow lift coefficient is accepted.
