Some experimental findings concerning the flutter characteristics
of two-dimensional supercavitating flat plate hydrofoils
are reported herein. The experiment was carried out in a freejet
water tunnel using wedge-shaped hydrofoils (practically rigid)
elastically supported to permit two-degree of freedom motions in
translational and rotational modes. Critical flutter speed, flutter
frequency, flutter amplitude ratio, and damping factor were
measured for various elastic and flow conditions. The measured
stability boundary curves agree, qualitatively,with an existing
