## What is iVSP?

The iVSP app allows users to steer ships equipped with Voith propulsion systems, in particular Voith Schneider Propeller (VSP). These are real ships of various types: Voith Water Tractors (tugs), double-ended ferries, offshore vessels, and yachts.
iVSP also provides a deeper insight into the mechanics and hydrodynamics of the Voith Schneider Propeller (VSP) and its unique propeller forces.
 
The VSP enables the fastest generation of thrust in all directions – stepless and precisely. VSPs combine propulsion, steering, and roll stabilization in a single unit, eliminating the need for rudders.  Thrust and steering forces can be generated in any direction from zero to maximum. The Voith Schneider Propeller generates thrust by means of profiled blades that protrude from the ship's bottom and rotate around a vertical axis. The blades are mounted in a rotor casing that is flush with the ship's bottom. The rotational movement of the blades around the common vertical axis is superimposed by a local oscillatory movement of the individual propeller blades around their own axis. This oscillatory movement is generated by a kinematic mechanism (kinematics).
The Voith Schneider Propeller is based on an idea by Austrian inventor Ernst Schneider, and its effectiveness was first successfully demonstrated in model tests in 1926.
 
The development potential of the VSP is far from exhausted, and Voith engineers are continuously working to further improve its efficiency. In addition, the company is constantly developing new applications for various types of ships for this unique propulsion system.
Suggestions for the application and further improvement of the VSP are always welcome. The relevant contact details for Voith can be found in the main menu of iVSP.

### 5/5 — Great Simulation

*2024-03-21, version 2.2.3*

Nice software that shows how these work. I only wish there were more scenarios and that the ferry was set up how she is in real life.

### 5/5 — Fantastic App

*2021-04-02*

Very interesting and informative! I would like to suggest the addition of a wharf or solid object to interact with in free driving mode as another reference and to improve operator manoeuvring!
Thankyou

### 5/5 — Excellent

*2020-04-01, version 2.1*

Great voith sim, can’t wait for ver 3.0
