Abstract
An arrangement for supplying heated air to a wing anti-icing system on an aircraft propelled by a jet engine includes, but is not limited to, an ejector that is configured for coupling to a wing anti-icing system. The ejector is further configured to receive a first flow of air, to entrain a second flow of air with the first flow of air, the second flow of air having a lower temperature than the first flow of air, to mix the first flow of air with the second flow of air to form a combined flow having a temperature and a volume suitable for use by the wing anti-icing system, and to exhaust the combined flow into the wing anti-icing system.
Claims18
An arrangement for supplying heated air to a wing anti-icing system on an aircraft propelled by a jet engine, the arrangement comprising:
- a pre-cooler configured to receive a flow of bleed-air from the jet engine, to receive a flow of cooling-air from a freestream, to cool the flow of bleed-air with the flow of cooling-air, to exhaust a flow of cooled bleed air, and to exhaust a flow of warmed cooling-air;
- and
- an ejector configured to:
- receive a portion of the flow of cooled bleed-air from the pre-cooler,
- to entrain a portion of the flow of warmed cooling-air with the portion of the flow of cooled bleed-air,
- to mix the portion of the flow of cooled bleed-air with the portion of the flow of warmed cooling-air to form a combined flow having a temperature and a volume suitable for use by the wing anti-icing system, and
- to exhaust the combined flow.
A method for supplying heated air to a wing anti-icing system on an aircraft propelled by a jet engine, the method comprising the steps of:
- receiving a flow of bleed-air from the jet engine and a flow of cooling-air from a freestream at a pre-cooler;
- cooling the flow of bleed-air with the flow of cooling-air at the pre-cooler;
- exhausting a flow of cooled bleed-air and a flow of warmed cooling-air from the pre-cooler;
- receiving a portion of the flow of cooled bleed-air at an ejector;
- entraining a portion of the flow of warmed cooling-air with the portion of the flow of cooled bleed-air at the ejector;
- mixing the portion of the flow of warmed cooling-air with the portion of the flow of cooled-bleed air at the ejector to form a combined flow;
- and
- exhausting the combined flow from the ejector.
