Abstract
An engine arrangement for a component subject to icing. The arrangement comprising a manifold as part of a flow path incident upon a heated component. The manifold including holes to create jets having an exit angle toward the component subject to icing. The jets of hot gas are entrained in a core flow passing through the main flow path before washing over a desired incident area of the component. The exit angle and spacing between the jet and the component are determined to reduce disruption of the core flow and/or provide the desired incident area on the component and/or use the minimum amount of hot air.
