Abstract
An anti-ice swirl system for an aircraft engine includes a nacelle including a first nacelle section exposed to ambient environment and facing an oncoming airstream when an aircraft powered by the engine is in flight. The first nacelle section defines a circumferential D-duct. The anti-ice swirl system also includes a nozzle configured to inject into and circulate through the D-duct a controlled unsteady flow of heated fluid. The controlled unsteady flow mixes newly injected heated fluid with air inside the D-duct and mitigates icing of the first nacelle section when the aircraft is in flight.
