Abstract
An on-board aircraft oxygen enriched air and nitrogen enriched air generation system and method are disclosed. In one embodiment, the system includes a first heat exchanger which is configured to receive pressurized air from a source of pressurized air. Further, the first heat exchanger cools the pressurized air to a temperature in the range of −120° C. to −70° C. Furthermore, a separation unit is configured and dimensioned to communicate with the first heat exchanger. The separation unit generates nitrogen enriched air and oxygen enriched air from the cooled air at the temperature range of −120° C. and −70° C.

An on-board aircraft system, comprising:
- a first heat exchanger configured to receive pressurized air from a source of pressurized air, wherein the first heat exchanger cools the pressurized air to a temperature in the range of −120° C. to −70° C.;
- and
- a separation unit configured and dimensioned to communicate with the first heat exchanger and to generate nitrogen enriched air and oxygen enriched air from the cooled air at the temperature range of −120° C. and −70° C.
A method for on-board generation of nitrogen enriched air and oxygen enriched air in an aircraft, comprising:
- feeding pressurized air into a first heat exchanger to cool the pressurized air to a temperature in the range of −120° C. to −70° C.;
- and
- feeding the cooled air at the temperature range of −120° C. and −70° C. into a separation unit and generating nitrogen enriched air and oxygen enriched air from the cooled air.
