Uniform Flow with Increased Thrust
Pre-Swirl Stators reduce the rotational losses incurred by the propeller and further increase the performance of the Nautican High Efficiency Nozzle. By directing the flow to swirl in the opposite direction of propeller rotation, energy that is normally lost in wake rotation is recovered. This increases thrust by an additional four to six percent.
Pre-swirl stators insure a more uniform inflow to the propeller and eliminate the need for struts and bossings, which are often a source of vibration.
The combination of Nautican High Efficiency Nozzles and Stators make the Nautican Integrated Propulsion Unit the most efficient propulsion system available.
