Abstract
An improved anti-icing system for a nose cowl of an aircraft jet engine. An improved injection nozzle is provided to passively enhance the injection of hot, pressure gas from the engine into the ambient air within the nose cowl to entrain such air and cause the entrained mass to rotate within the nose cowl in swirling rotational motion and thereby cause the temperature of the skin of the nose cowl to rise sufficiently to preclude the formation of ice thereon during flight. A plurality of spaced circumferentially arranged tab members, that are preferably triangularly shaped, are canted inwardly slightly to create large scale longitudinal vortices and transverse stirring during the introduction of hot gas and thereby enhance its mixture with the ambient air within the nose cowl and thereby preclude any tendency for the formation of an area of elevated temperature in the skin of the nose cowl downstream of the position of the injection nozzle under certain severe design conditions.
