Reuse of waste oxygen enriched air in aircraft

The invention relates to reuse of waste oxygen enriched air in an aircraft, and especially tp aircrafts and methods for reusing oxygen enriched air. In one example, an aircraft includesan oxygen supply subsystem configured to supply oxygen to a cabin of the aircraft, and an air separator configured to receive a pressurized air stream, to separate the pressurized air stream into oxygen enriched airand an inert gas, and to feed the oxygen enriched air to the oxygen supply subsystem. 本发明涉及废弃富氧空气在飞行器中的再利用，尤其是涉及用于再利用富氧空气的飞行器和方法。在一个实施方式中，飞行器包括被构造成向飞行器的机舱供应氧气的氧气供应子系统，以及被构造成接收加压气流、将加压气流分离成富氧空气和惰性气体、以及将富氧空气供给到氧气供应子系统的空气分离器。
