VOITH-SCHNEIDER PROPULSION UNIT

Voith-Schneider Propulsion Unit

True-scale propeller drive unit for powering and controlling model boats. The new Voith-Schneider propeller unit (usual abbreviation VSP) for model boats was developed with the help of original factory drawings. At the design stage we insisted that all the basic functions should emulate those of the original. In the Voith-Schneider system the propeller generates both thrust and steering forces by altering the angle of the propeller blades.

Changes in speed are produced by altering the pitch angle of the propeller blades; motor speed remains constant. Thrust vectoring is used to alter the direction of running, with infinite variation available through 360º without any change in the direction of motor rotation. For this reason only a simple motor switch or a forward-only speed controller is required for the motor.

The VSP is designed as a robust slow-running unit (the SPEED 500 E 12V motor supplied is fitted with an appropriate reduction gearbox). In an effort to generate as little noise as possib
