EXPERIMENTAL INVESTIGATION OF SUPERCAVITATING HYDROFOIL FLUTTER PHENOMENA

Abstract

Tests were made to obtain the experimental flutter characteristics of a supercavitating hydrofoil with a control surface. No attempt is made to fix a theory to the data; rather, the data are presented just as obtained. In general, the foil responses obtained resulted in two flutter speeds per configuration. Each flutter condition was a limited-amplitude sinusoidal oscillation. The control surface participated in each flutter mode and torsion was present in the flutter mode at 40 fps. Very little bending was noted in any supercavitating flutter mode. The speed may be increased to speeds above the flutter speed with increasing stability; however, prolonged running at the flutter speed may result in fatigue failure or difficulties affecting passenger comfort.
