Abstract
An article for mixing ambient fluid with a motive fluid comprises a conduit, and thermally conductive concentric inner and outer nozzles extending from the conduit. The conduit is configured to supply the motive fluid to the outer nozzle and the ambient fluid to the inner nozzle. The inner nozzle extends further downstream from the conduit than the outer nozzle.
Claims20
An article for mixing ambient fluid with a motive fluid, the article comprising:
- a conduit;
- and
- thermally conductive concentric inner and outer nozzles extending from the conduit;
- the conduit configured to supply the motive fluid to the outer nozzle and the ambient fluid to the inner nozzle;
- wherein the inner nozzle extends further downstream from the conduit than the outer nozzle.
2 more elements
An engine nacelle lipskin comprising:
- a channel forming a lipskin cavity;
- and
- an article including a conduit and thermally conductive concentric inner and outer nozzles extending from the conduit, the conduit secured to the channel such that the nozzles are located within the cavity and oriented in a direction of anti-icing flow, the conduit configured to supply motive fluid to the outer nozzle and ambient fluid within the cavity to the inner nozzle.
A method comprising:
- mounting thermally conductive concentric inner and outer nozzles within a lipskin cavity of an engine nacelle such that ambient air flowing within the cavity is supplied to an inlet of the inner nozzle;
- and
- coupling a bleed air source to an inlet of the outer nozzle.
A method comprising heating an engine nacelle lipskin, including:
- ejecting a jet stream of high pressure, high temperature air into a cavity of the lipskin via a nozzle, wherein ambient air surrounding the nozzle mixes with the jet stream;
- and
- supplying a stream of ambient air through a central portion of the jet stream, wherein the jet stream expands to ambient pressure before being mixed with the ambient air stream.
