Abstract : Measured values of the flutter speed and response characteristics of an aspect-ratio-4, surfacepiercing strut supported with two degrees of freedom are compared with values predicted for two-dimensional flow in an infinite fluid. The measured and predicted flutter speeds and frequencies are in agreement, but the predicted damping at speeds below flutter is considerably higher than measured values. Reasons to doubt the reliability of infinite fluid theory for hydrofoil flutter speed prediction are discussed. (Author)
