Abstract
A system for an aircraft includes an engine bleed source of a gas turbine engine. The system also includes a means for chilling an engine bleed air flow from the engine bleed source to produce a chilled working fluid. The system further includes a means for providing the chilled working fluid for an aircraft use.
Claims17
A system for an aircraft, the system comprising:
- an engine bleed source of a gas turbine engine;
- a means for chilling an engine bleed air flow from the engine bleed source to produce liquid air comprising a cryogenic cooling system comprising a heat exchanger system operable to pre-cool the engine bleed air flow, a compressor operable to further compress the engine bleed air flow as compressed air, and at least one turbine operable to expand and cool the compressed air as a cooled flow, wherein the heat exchanger system is configured to receive a cooling air intake that pre-cools the engine bleed air flow and cools the compressed air from the compressor prior to reaching the at least one turbine;
- and
- a means for providing the liquid air for an aircraft use.

A method comprising:
- providing an engine bleed air flow from an engine bleed source of a gas turbine engine to a cryogenic cooling system;
- chilling the engine bleed air flow using the cryogenic cooling system to produce liquid air by:
- pre-cooling the engine bleed air flow using a heat exchanger system;
- compressing the engine bleed air flow as compressed air by a compressor of the cryogenic cooling system;
- and
- expanding and cooling the compressed air as a cooled flow by at least one turbine of the cryogenic cooling system, wherein a cooling air intake is received at the heat exchanger system that pre-cools the engine bleed air flow and cools the compressed air from the compressor prior to reaching the at least one turbine;
- and
- pumping the liquid air for an aircraft use.
