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 ...
Two Voith-Schneider cycloidal propeller-rudders were to be installed in the forward bow of the ship along the center-line. These were intended to assist in berthing the ship in harbor and also in negotiating narrow waterways such as the Kiel Canal where, due to the carrier's high freeboard and difficulty in maneuvering at speeds below 8 knots ...
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.
The cycloidal propeller (see below) was developed prior to World War II and was occasionally used in tugs because of its maneuverability. After World War II it was also linked to safety due to the development of the Voith Water Tractor, a tugboat configuration that could not be pulled over by its tow.
They are propelled by two Voith Schneider cycloidal propellers turned by two Ruston-Paxman diesel engines rated at 1,300 horsepower (969 kW). [1] This gives them a maximum speed of 11.5 knots (21.3 km/h; 13.2 mph). They initially had a complement of six officers and ratings. [1]
Twin 6-cylinder turbocharged Mirrlees Blackstone engines mounted at 45 degrees across each engine room drove Voith Schneider cycloidal propellers. Unlike the earlier pioneer C-class ship Cuthred, the main engines were not additionally loaded by a generator, so larger Voith Schneider units were fitted and there was considerably more propulsive ...
Protector 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. [1] She is 108 feet long, with a maximum speed of 13 knots.
