International Classification:

F02C 7/06
F02C 1/00
F02K 99/00
F01D 25/18
F02K 9/64

US Classification:

60 3908, 60266, 60267, 60772

Abstract:

A lubricant supply system for a gas turbine engine has a lubricant lube pump delivering lubricant to an outlet line. The outlet line is split into at least a hot line and into a cool line, with the hot line directed primarily to locations associated with an engine that are not intended to receive cooler lubricant, and the cool line directed through one or more heat exchangers at which lubricant is cooled. The cool line then is routed to a fan drive gear for an associated gas turbine engine. A method and apparatus are disclosed.

F02K 99/00

US Classification:

60 3908, 60266, 60267, 60772

Abstract:

A thermal management system for a gas turbine engine includes a first heat exchanger that provides a first conditioned fluid, a second heat exchanger in series flow communication with the first heat exchanger and that exchanges heat with the first conditioned fluid to provide a second conditioned fluid, and a third heat exchanger in parallel flow communication with the second heat exchanger and that selectively exchanges heat with the first conditioned fluid to provide a third conditioned fluid. The second conditioned fluid and the third conditioned fluid combine to provide a mixed conditioned fluid. A first portion of the mixed conditioned fluid including a first temperature is communicated to a first engine system. A second portion of the mixed conditioned fluid including a second temperature is communicated to a second engine system. The second temperature includes a greater temperature than the first temperature.

Appl. No.:

13/360745

Inventors:

Xiaojun Campbell - East Hampton CT, US
Thomas G. Phillips - Coventry CT, US
Kathleen R. Phillips - Coventry CT, US

International Classification:

F02C 6/08

US Classification:

60785

Abstract:

A gas turbine engine has a fan, a compressor section, a combustor, and a turbine section. The fan delivers a portion of air into the compressor, and into a duct, as bypass air. A bleed air system bleeds a quantity of air from the compressor into a chamber at least at low power conditions of the engine. The bleed air system has an opening which may be selectively closed to block bleed air, or opened to allow bleed flow from the compressor into the chamber. A heat exchanger is positioned such that a first surface of the heat exchanger is contacted by bypass air in the duct, and a second surface of the heat exchanger is contacted by bleed air when the bleed air system directs air from the compressor into the chamber.

International Classification:

F01D 25/12

US Classification:

415 1, 415177

Abstract:

A thermal management system for a gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a heat exchanger and a valve that controls an amount of a first fluid that is communicated through the heat exchanger A first sensor senses a first characteristic of a second fluid that is communicated through the heat exchanger to exchange heat with the first fluid and a second sensor senses a second characteristic of the second fluid. A positioning of the valve is based on at least one of the first characteristic and the second characteristic.

Inventors:

Thomas G. Phillips - Coventry CT, US
Kathleen R. Phillips - Coventry CT, US

International Classification:

F02C 7/14

US Classification:

165 51

Abstract:

A thermal management system according to an exemplary aspect of the present disclosure includes, among other things, a first fluid circuit that selectively communicates a first portion of a first conditioned fluid having a first temperature to a first gas turbine engine system and a second portion of the first conditioned fluid having a second temperature to a second gas turbine engine system. The second temperature is a greater temperature than the first temperature. A second fluid circuit circulates a second conditioned fluid that is different from the first conditioned fluid to a third gas turbine engine system.
