Assignee:

AlliedSignal, Inc. - Morris Township NJ

International Classification:

F02C 300
F02C 712

US Classification:

60 3975

Abstract:

An exhaust housing having an eductor is provided. The eductor includes an outer annular casing circumscribing an inner annular casing to define a flow path therebetween for receiving the exhaust gas from the turbine section of an engine. A plurality of struts are integral with both casings. The struts have passages that extend from the exterior of the outer casing to the interior of the inner casing. A non-oil lubricated bearing is mounted within the interior of the inner casing for journaling a rotating shaft. During operation, the kinetic energy of the high velocity exhaust gas flowing between the casings and into a tailpipe induces cooling airflow from the exterior of the exhaust section, through the passages, across the bearing, and then out to the tailpipe.

Abstract:

A reverse flow annular combustor is provided having downstream wall comprised of a shroud covering the outer surface of the outer transition liner. The shroud abuts the transition liner at a plurality of points to define a plurality of passages between the shroud and the liner. The passages receiving cooling through the shroud at its radial inner end and expel the cooling air through the liner at its outer radial portion and into the hot gas in the combustor. Thus, the air used to cool the liner is also used for dilution mixing with the combustion gas.
