FLUTTER OF A TWO-DEGREE-OF-FREEDOM HYDROFOIL IN TWO-DIMENSIONAL SUBCAVITATING FLOW
1970
Cieslowski, Daniel S | Besch, Peter K
Four hydrofoil flutter tests were performed in a towing basin and a 36-inch water tunnel using a two-degree-of-freedom hydrofoil in two-dimensional flow. Mass ratio, mass unbalance, heave stiffness, angle of attack, and foil depth were varied. All of these parameters significantly affected the flutter boundaries. Comparisons were made with a flutter theory based on the Theodorsen analysis. Theory gave good flutter predictions at high mass ratios but failed at low mass ratios.
