Voith Schneider Propeller

Voith Schneider Propeller (VSP)

The Voith Schneider Propeller (VSP) combines propulsion and steering in one unit. This unique vessel propulsion solution was developed 90 years ago by Austrian engineer Ernst Schneider. Today Voith Schneider Propellers are in use all over the world wherever precise, safe and efficient maneuvering is of the essence.

The VSP principle is strikingly simple and fascinating at the same time:

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.

iVSP 2.0

iVSP 2.0 invites you to be your own captain and explore the unique technology of the Voith Schneider Propeller (VSP).

The VSP is the safest and most accurate drive system for ships: thrust can be varied extremely fast, steplessly and precisely into all directions.

Perhaps you still remember the predecessor program iVSP? It certainly helped to explain the VSP technology, but the ship sailed without illustrating the complex physical effects. With the new version you get a quasi-realistic on-board experience of the advantages of the VSP, and also gain a 3D insight into the heart of the VSP – its kinematics.

The program iVSP 2.0 has three menu points: “Free Driving Mode” “Kinematics & Forces” and “Active Simulation Training.”

The vessel that you will find under the menu points “Free Driving Mode“ and/or “Active Simulation Training“ is ready to sail and depicted as realistically as possible: the forces of the VSPs, the hydromechanics of the ship and all inertia effects are accurately captured in a time simulation. In the range “Active Simulation Training“ you can test your capabilities of steering a VSP-driven ship in a contest with other captains.

Under “Kinematics & Forces“you learn how the unique mechanics and hydromechanics of the Voith Schneider Propeller work. Take your time: alternate between the buttons “Kinematics“ and “Hydrodynamic Forces“, modify the speed, the longitudinal and transverse thrust, and monitor the movements of the kinematics and/or the generation of hydrodynamic forces. Witness how the secret of the VSP is being revealed.

We wish you a great time on board - Voith Turbo Mobility.

Controlling a virtual Voith Schneider Propeller

"I hear and I forget; I see and I remember; I do and I understand." In full accordance with this quotation by Confucius, Voith Turbo Schneider Propulsion has developed the iVSP (Interactive Voith Schneider Propeller) program in English and German. With the help of this program you can experience for yourself how a Voith Schneider Propeller (VSP) actually works.

Viewers can play captain by using their mouse to control an on-screen steering wheel and lever or, alternatively, an on-screen joystick. The virtual VSP reacts immediately and visibly to any change in rudder or driving pitch. A kinematic or hydrodynamic viewing option illustrates the actual VSP operation. The relevant forces are shown by arrows in different colors.
The maneuvers performed by the ship are displayed in the upper right hand part of the screen. A Voith Water Tractor (VWT) can be watched during its maneuvers from a bird's eye perspective (a camera linked to the VWT). The compass in the right-hand corner indicates the sailing direction.
