Further Calculations of the Flutter Speed of a Fully Submerged Subcavitating Hydrofoil

Abstract

Some new calculations of the flutter speed of the fully submerged subcavitating hydrofoil model are presented. Variations in lift curve slope and in center of pressure location are found to have a most profound influence on both flutter speed and frequency. When variations in these parameters are combined with a relaxation of the Kutta condition (proposed previously), excellent agreement with the measured flutter speed is obtained.
