Abstract
As a part of the research for developing pitch-adapted marine propellers, a deformable hydrofoil with composite materials was designed and manufactured. Hydroelastic behavior of the deformable hydrofoil were studied in a large cavitation tunnel at the Naval Systems Research Center. Displacements of target points on the hydrofoil were measured using a laser distance meter and a high speed video camera. Measured hydrofoil deformation was in a good agreement with the computations of the fluid-structure coupled analysis.
