Abstract
A cycloidal dynamic propulsion or positioning system for a ship in water that exhibits a direction of flow, including a frame, a rotor mounted to be movable in rotation on the frame about a main axis at right angles to the flow, including a plurality of arms extending radially with respect to the main axis, a main motor equipped with a rotary coder and driving the rotor in rotation, for each arm, a blade mounted to be movable in rotation on the arm about a secondary axis parallel to the main, for each blade, a secondary motor equipped with a rotary coder and driving the blade in rotation, for at least one blade, a load sensor able to evaluate the loads exerted on the blade, and a control unit connected to each coder, strain sensor and motor and controlling the rotation of each motor in terms of angle and speed.
