Brunvoll’s commitment to
innovation – RDT development,
testing and pilots
The thruster, propeller and motor are in one compact unit
– there is no need for an external motor, shafts or couplings.
With no gap between the propeller tips and the duct or
tunnel, propeller efficiency is higher, while noise and
vibration levels are exceptionally low.
The compact design increases arrangement flexibility and
makes more space available on board.
The RDT can be fitted in places where there is little room for
conventional thrusters.
