THEORY OF THE DETERMINATION OF FLUTTER SPEED OF A CLASS OF HYDROFOILS

A theory is given for the determination of the flutter frequency and speed of a hydrofoil traveling at a constant speed. This work used the work of Sears to determine the fluctuating lift and combined it with the chordwise and transverse drag forces to determine flutter speeds. It is shown that flutter speed is sensitive to the drag coefficient as well as lift curve slopes. The theoretical results obtained are shown compared with an experimental study conducted by Huang.
