Objective To analyze the protective performance of airborne oxygen and oxygen system and verify the high altitude protection effect of the system. Methods The aerobic performance of the airborne oxygen concentrator was tested in the low pressure cabin and the rapid decompression cabin. The oxygen supply performance of 0 ~ 80 000 m, the long-time oxygenation test of cruise flight, the alarm performance test, the altitude spare oxygen Switching human experiments, high-altitude pressurized oxygen performance experiments and rapid decompression experiments. Results Airborne oxygen and oxygen supply system oxygen production capacity, the normal oxygen supply capacity and emergency oxygen performance, to meet the physiological requirements of the system. Conclusion The airborne oxygen and oxygen supply systems can meet the normal oxygen supply and emergency oxygen supply requirements of pilots flying at high altitude for a long time.
