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.
Claims16
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 a chilled working fluid at a temperature below a boiling point of oxygen and above a boiling point of nitrogen;
- a means for separating gaseous nitrogen from the chilled working fluid as a gaseous nitrogen supply and separating liquid oxygen from the chilled working fluid as a liquid oxygen supply;
- and
- a plumbing system comprising:
- a feeder line coupled to an output of the means for chilling the engine bleed air flow;
- a pump in fluid communication with the feeder line, the pump operable to urge the chilled working fluid for an aircraft use through the plumbing system;
- and
- a valve operable to direct a portion of the chilled working fluid to the means for separating gaseous nitrogen.

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 a chilled working fluid at a temperature below a boiling point of oxygen and above a boiling point of nitrogen;
- urging, by a pump in fluid communication with a feeder line of a plumbing system, the chilled working fluid from the feeder line for an aircraft use of an aircraft through the plumbing system, wherein the feeder line is coupled to an output of the cryogenic cooling system;
- directing, by a valve of the plumbing system, a portion of the chilled working fluid to a cryogenic air separator;
- separating, by the cryogenic air separator, gaseous nitrogen from the chilled working fluid as a gaseous nitrogen supply;
- and
- separating, by the cryogenic air separator, liquid oxygen from the chilled working fluid as a liquid oxygen supply.
