Abstract (en)
The present invention concerns an oscillating foil propulsion system (1) comprising at least one movable foil (2,3), at least one pitch mechanism connected to the at least one movable foil (2,3) and configured to control a pitch motion of the at least one movable foil (2,3), at least one heave mechanism connected to the at least one movable foil (2,3) and configured to control a downstroke heave motion and an upstroke heave motion of the at least one movable foil (2,3), and wherein the at least one pitch mechanism is configured to control a pitch angle of the at least one foil (2,3) such that a thrust force and a drag force are obtained during a downstroke heave motion, and the at least one pitch mechanism is configured to control a pitch angle of the at least one foil (2,3) such that an induced drag force during an upstroke heave motion is substantially smaller than the drag force during the downstroke heave motion. The invention further concerns a method for oscillating at least one movable foil (2,3).
