GAS TURBINE ENGINE DRIVEN BY SCO2 CYCLE WITH ADVANCED HEAT REJECTION
First Claim
1. A gas turbine engine, comprising:
- a shaft comprising a first compressor, a fan assembly, and a power circuit that provides power to the shaft in a closed-loop system;
an inner housing that houses;
at least a portion of the shaft;
the first compressor for compressing a core stream of air; and
a combustor;
a baffle that encloses a portion of the inner housing and forms a first air passageway therebetween;
a nacelle that encloses a portion of the baffle and forms a second air passageway therebetween;
a heat exchanger positioned in the second air passageway that rejects heat from the power circuit into a heat rejection stream of air passing through the second air passageway;
wherein air is accelerated as streams in parallel and via the fan assembly;
as the core stream into the inner housing;
as a bypass flow stream of air through the first volume; and
as the heat rejection stream.

Abstract
A gas turbine engine includes a shaft comprising a first compressor, a fan assembly, and a power circuit that provides power to the shaft in a closed-loop system. An inner housing houses at least a portion of the shaft, the first compressor for compressing a core stream of air, and a combustor. A baffle encloses a portion of the inner housing and forms a first air passageway therebetween. A nacelle encloses a portion of the baffle and forms a second air passageway therebetween. A heat exchanger is positioned in the second air passageway that rejects heat from the power circuit into a heat rejection stream of air passing through the second air passageway. Air is accelerated as streams in parallel and via the fan assembly as the core stream into the inner housing, as a bypass flow stream of air through the first volume, and as the heat rejection stream.

9. A method of providing power, comprising:
-
accelerating air as streams in parallel and via a fan assembly, the streams comprising; a core stream; a bypass flow stream; and a heat rejection stream; passing the core stream into an inner housing that houses; at least a portion of the shaft; the first compressor for compressing the core stream; and a combustor; passing the bypass flow stream external to the inner housing and into a first air passageway that is formed between a baffle and the inner housing; passing the heat rejection stream through a heat exchanger that is positioned in a second air passageway that is formed by a nacelle, that encloses at least a portion of the baffle, and the baffle; providing power to a gas turbine engine shaft via a power circuit that provides power to the shaft in a closed-loop system; and cooling the heat rejection stream in the heat exchanger. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A power-producing device, comprising:
-
an inner housing for passing a core stream of air, the inner housing houses; at least a portion of a shaft; a first compressor for compressing a core stream of air; and a combustor; a nacelle that encloses a portion of the inner housing and forms a first air passageway therebetween for passing a heat rejection stream of air; and a heat exchanger positioned in the first air passageway that rejects heat from a power circuit into a heat rejection stream of air passing through the second air passageway; wherein the core stream and heat rejection stream are accelerated in parallel and via the fan assembly. - View Dependent Claims (18, 19, 20)
