Voith Schneider Propeller
Voith Schneider Propeller (VSP) cycloidal propeller.
"The Voith Schneider propeller (VSP), also known as a cycloidal drive (CD) is a specialized marine propulsion system (MPS). It is highly manoeuvrable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries.
From a circular plate, rotating around a vertical axis, a circular array of vertical blades (in the shape of hydrofoils) protrude out of the bottom of the ship. Each blade can rotate itself around a vertical axis. The internal gear changes the angle of attack of the blades in sync with the rotation of the plate, so that each blade can provide thrust in any direction, very similar to the collective pitch control and cyclic in a helicopter." -- Wikipedia
