The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...

The device is different from the Voith-Schneider marine propulsion system (also mechanically linked), which can also quickly change the direction of thrust, as the Z-drive uses a shrouded conventional screw that pivots or rotates the propeller, unlike the variable-geometry blades of the Voith-Schneider.
A Voith Schneider Propeller (VSP) is a practical cyclorotor that provides instant thrust in any direction. There is no need to turn a propulsor. There is no need to turn a propulsor. Most ships with VSPs do not need or have a rudder.
VoithâSchneider propeller. The Voith Schneider Propeller, also known as a cycloidal drive is a specialized marine propulsion system. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries.
A more serious problem with this type of propeller is a "frozen-on" spline bushing, which makes propeller removal impossible. In such cases the propeller must be heated in order to deliberately destroy the rubber insert. Once the propeller is removed, the splined tube can be cut away with a grinder and a new spline bushing is then required.
Marine thrusters come in many different shapes and sizes, for example screw propellers, Voith-Schneider propellers, waterjets, ducted propellers, tunnel bow thrusters, and stern thrusters, azimuth thrusters, rim-driven thrusters, ROV and submersible drive units.
In 1927, the Viennese engineer Ernst Schneider and the Voith company in Sankt Pölten applied jointly for a patent for the Voith Schneider propeller, which had been developed the year before based on the former's plans. This marine propulsion system, which also acts as a steering device, allows maneuverability previously impossible.
