Voith-Schneider
The first functional design was developed at Voith in the 1930s. Its origins date to the decision of the Voith company to focus on turbine transmission gear assemblies. The Voight propeller was invented by Ernst Schneider and enhanced by Voith. It was launched as the Voith-Schneider Propeller (VSP) for commercial marine vessels. It significantly improved ship manoeuvrability as demonstrated in sea trials on the test boat Torqueo, in 1937. The first Voith Schneider Propellers were put to work in the canals of Venice, Italy. During the 1937 World Fair in Paris, Voith was awarded the grand prize – three times – for its propellers and turbo-transmissions. A year later, two of Paris' fire-fighting boats started operating with the system.
