Abstract
A gas turbine engine is provided with a first heat exchanger associated with a cooling air flow to deliver cooling air to a turbine section. A second heat exchanger is associated with a fuel supply line for delivering fuel into a combustion section. An intermediate fluid cools air at the first heat exchanger and heats fuel at the second heat exchanger.
Claims10
1 A system for cooling air in a gas turbine engine comprising:
- a first heat exchanger to be in contact with cooling air to be delivered to a turbine section in a gas turbine engine;
- a second heat exchanger to be positioned adjacent to a combustion section in the gas turbine engine, and the second heat exchanger positioned to be in contact with fuel being delivered into the combustion section;
- and
- an intermediate fluid for transferring heat from the first heat exchanger to the second heat exchanger.
The cooling system as set forth in claim 1, wherein there are a plurality of heat exchangers associated with locations for cooling air communicating with one heat exchanger for heating the fuel.
The cooling system as set forth in claim 1, wherein the intermediate fluid is provided by a heat pipe.
The cooling system as set forth in claim 1, wherein there are a plurality of circumferentially spaced first and second heat exchangers and intermediate fluids.
A gas turbine engine comprising:
- a compression section;
- a combustion section;
- a turbine section;
- and
- said combustion section including a fuel supply for delivering fuel into the combustion section;
- a first heat exchanger to be in contact with cooling air to be delivered to the turbine section in a gas turbine engine;
- a second heat exchanger to be positioned adjacent the fuel supply system, and the second heat exchanger positioned to be in contact with fuel being delivered into the combustion section;
- and
- an intermediate fluid for transferring heat from the first heat exchanger to the second heat exchanger.
