The Voith Schneider propeller is a highly efficient boat propeller that allows for precise control without the need for a rudder. It uses rotating hydrofoil-shaped blades to direct thrust in all directions, making it popular on tugboats, fire boats, and aircraft carriers. However, the blades can be a disadvantage in shallow waters.
A Voith Schneider propeller is a highly efficient boat propeller made up of rotating hydrofoil-shaped blades that extend downward from a circular plate under a boat. The Voith Schneider propeller blades can be controlled by the boat’s captain to drive the boat forward and backward, as well as left and right without delay or hesitation. So effective is the Voith Schneider propeller in propelling and steering the boat that boats equipped with this type of propeller do not use a rudder to steer the boat. Ships that commonly use this propeller are tugboats, fire boats, and even some types of aircraft carriers among others throughout the world.
By changing the angle of the hydrofoil-shaped blades on the turntable, a Voith Schneider propeller can change the direction of the thrust created by the blades. This allows a boat equipped with the Voith Schneider propeller to operate without the need for a rudder. Many vessels, such as ferries, that require extreme control rely on this type of propulsion system to maneuver in and out of berthing positions. In a tug application, the maneuverability allowed by the propeller allows the tug captain to make small adjustments in the direction of thrust or pull without hindering the movement of the vessel, maintaining a smooth flow of motion.
Commonly arranged in pairs, the Voith Schneider propeller commonly uses six vertical rotating blades per propeller to direct thrust in all directions as the captain deems necessary. The low acoustic output of the Voith Schneider propeller made it a favorite on World War II minesweeper boats used by Germany and Japan. The German navy also installed the Voith Schneider propeller in pairs at the bow of some aircraft carriers to aid in maneuverability while in port or while docked. More recently, the propulsion system is being used on offshore platforms as well as the various platform supply vessels, allowing vessels to be easily controlled as they unload their supplies in rough waters.
The tremendous thrust capability of the Voith Schneider propeller allows a unit to maintain control of a vessel in the event of an engine failure. One disadvantage of the propulsion system is that the hydrofoil-shaped blades protrude from the bottom of the vessel. This can create problems if the boat enters shallow water and the blades hit the bottom, rocks, or other underwater objects.
