The purpose of on-board membrane air separation module is to supply nitrogen-enriched air (NEA) for aircraft fuel tank inerting. The experiment and the analysis, based on on-board membrane air separation module designed by a domestic factory are systemically implemented by the ground simulation. Results show that: (1) the separation performance of the membrane module is mainly influenced by the input air pressure output product flow and the height above sea level (back pressure), especially under the condition of the low height above sea level when the low input air pressure large output product flow; (2) it is also affected by the surrounding temperature whether the module's height above sea level or not; (3) it has a little effect by the input air temperature. It is pointed out that the correspondence and the match of both output product flow and oxygen density of NEA in the actual process must be considered to meet the requirement of aircraft fuel tank inerting by balancing the above factors.
