CORRELATION OF VARIOUS SUBCAVITATING HYDROFOIL FLUTTER PREDICTIONS USING MODIFIED OSCILLATORY LIFT AND MOMENT COEFFICIENTS.
Abstract
Flutter calculations were performed for a simple unswept cantilever subcavitating hydrofoil using theoretical twoand three-dimensional oscillatory coefficients, measured three-dimensional oscillatory coefficients, and various modifications of these coefficients. Conclusions based on comparisons of these calculations with the observed flutter speed are that theoretical predictions of hydrofoil flutter can be highly unconservative, indicating the need for more satisfactory flutter prediction techniques and reliance on flutter model testing.
