Rolls Royce Rim Driven Thruster

One key area of interest is the potential impact of rdps on hydrodynamic efficiency.

Rolls royce rim driven thruster.

This technology is based on electric drive where the motor is in the form of a ring round the propeller. This will be followed by two smaller frame sizes 085 and 100 and one larger the 150 so that this azimuth thruster series will in due course span a power range from 900kw to 5 000kw. Our thruster support pool provides replacement units enabling the exchange of a complete shipset of azimuth and tunnel thrusters or just a single thruster as part of a planned maintenance solution. This level of benefit is also reflected in the information published by rolls royce on its rim driven thruster technology.

The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.

The permanent magnet tunnel thruster tt pm is our latest tunnel thruster design and has been engineered with reliability and through life costs as the focus. First to be introduced to the market is the azp pm l drive 120 size rated at 1 800 3 500kw continuous. Rim drive propellers or rim driven propulsers and thrusters voith rdp.

At the same time t. Permanent magnet technology the pm tunnel thruster technology offers numerous advantages over traditional tunnel thrusters including significant reduction i. In response to our customers needs we have launched the thruster support pool tsp. They will cover the speed range up to 24 knots.

Initial published research based on a scaled cruiseship model estimated that an efficiency improvement in the order of 7 was achievable.
