The performance of the H-E nozzle has been further increased with the development of the pre-swirl stator. By directing the flow to swirl in the opposite direction of propeller rotation, energy that is normally lost in wake rotation is now recovered. This increases thrust by an additional 4-6%.  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 H-E nozzles and stators make the NautiCAN Integrated Propulsion unit the most efficient propulsion system available.
