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 cyclorotor, cycloidal rotor, cycloidal propeller or cyclogiro, is a fluid propulsion device that converts shaft power into the acceleration of a fluid using a rotating axis perpendicular to the direction of fluid motion. It uses several blades with a spanwise axis parallel to the axis of rotation and perpendicular to the direction of fluid ...
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.
They are propelled by two Isotta Fraschini ID 36 SS 8V AM diesel engines which drive generators feeding two Voith Schneider cycloidal propellers generating 1,600 horsepower (1,200 kW). [2] They have a max speed of 12 knots (22 km/h), and a maximum operational range of 1,500 nautical miles (2,800 km). [4]
The ships are fitted with two diesel motors driving two Voith Schneider Propellers; these cycloidal propellers eliminate the need for the aft two active rudders. [9] The ships use a Raytheon/Thomson Sintra SQQ-32 VDS sonar for minehunting, and Alliant SLQ-48 remote vehicles for mine disposal. [9]
The ship's propulsion is transmitted via shafts to two Voith-Schneider Voith Turbo 21 GH / 160 cycloidal propellers. In order to increase the maneuverability of the unit and at the same time increase the ship's safety level, ORP "Albatros" was also equipped with a Schottel STT 170 AMAG bow thruster with a power of 100 kW. Such a configured ...
As manoeuvrability in such areas is critical the Voith-Schneider cycloidal propulsor is commonly used, allowing the engine thrust to be transmitted in any direction.
Sure, the topic of Voith Schneider propellers is related to other forms of cycloidal drives, like helicopters. But it is also related to the Z-drive, because both drives can change direction very rapidly, and eliminate the need for a traditional rudder. Someone could argue that Z-Drive and Voith Scheider propellse should be in a single article.
