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 ...
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.
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.
An advanced type of propeller used on the American Los Angeles-class submarine as well as the German Type 212 submarine is called a skewback propeller. As in the scimitar blades used on some aircraft, the blade tips of a skewback propeller are swept back against the direction of rotation. In addition, the blades are tilted rearward along the ...
A typical DP set-up for a PSV is two thrusters located at the bow of the vessel which can be supplemented by two azimuth thrusters or Voith Schneider Propellers located at the stern. All modern PSVs are DP2 rated, meaning that there are two levels of redundancy in the DP system.
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.
The Vigilance is propelled by a pair of Voith-Schneider propellers, an advanced propulsion system that bears some resemblance to helicopter propulsion, and enable instantaneous changes in the propeller thrust. [2] It is 108 feet long, with a maximum speed of 13 knots.
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.
