Product Description

Contra Rotating Propeller Multi Purpose Propulsion Dynamometer

The Contra Rotating Propeller Multi Purpose Propulsion Dynamometer is a generic design for use either within a large Cavitation Tunnel or within underwater models in the Towing Carriage. In this case is to be supplied for use in both facilities with the appropriate equipment and accessories including a separate water cooling system for the integral motors.

The new CRP dynamometer is based on the Dynamometer principle of integral motors in the gondola, however with higher ratings to meet our customers requirements. The design greatly simplifies the transmission of power to the output shafts and reduces the number of moving parts (and thus generated noise) considerably..
