EXPERIMENTAL AND THEORETICAL INVESTIGATION OF LARGE AMPLITUDE OSCILLATION FOIL PROPULSION SYSTEMS

Abstract

This report presents an analytical method for computing the forces and moments on a rigid foil of finite span undergoing large amplitude pitching, heaving, and surging oscillations. The influence of foil stall and the induced slipstream are included. Experimental data obtained on a large amplitude oscillating foil propulsor are presented and compared with the theory. Performance predictions for an oscillating foil propulsor for use on a small, 15 knot, shallow-draft boat are also presented. (Author)
