The latest unit in Brunvoll's thruster familiy is the RDT2100 - a rim driven tunnel thruster of 2,1 meter propeller diameter and a power range up to 1600 kW.
RDT2100 is a result of the market demand, and the first units are for an SOV-project.
A rim driven thruster is eqiupped with a permanent magnet (PM) motor integrated in the thruster unit.
The PM-motor operates at a low speed and is combined with a large ring propeller with a high number of blades.
The Brunvoll RDT is hence a compact and low-noise thruster.
As for all Brunvoll thrusters emphasis has been put on designing a competitive thruster with low life cycle costs.
