Voith Schneider Propeller
With the VSP, magnitude and direction of thrust can be set stepless and as necessary. A circular disk with movable and controllable blades installed at a 90 degree angle to the disk rotates at the vessel bottom.
The magnitude of thrust is determined by the rotational speed of the disk; the blade angle determines the direction of thrust. A perfect propulsion system for precise maneuvering, even under adverse conditions.
