The molecular sieve method of generating an enriched-oxygen breathing gas is one of several candidate onboard oxygen generation (OBOG) systems under joint Army-Navy-Air Force development for application in tactical aircraft. The performance of a nominal two-man-capacity molecular sieve oxygen generation system was characterized under simulated flight conditions. Data are given on the composition of the molecular sieve-generated breathing gas (oxygen, nitrogen, carbon dioxide, and argon) as a function of inlet air pressure, altitude, breathing gas flow rate, and ambient temperature. The maximum oxygen concentration observed was 95%, with the balance argon. At low demand flow rates and certain conditions of pressure and altitude, the argon enrichment factor exceeded that of oxygen giving a maximum argon concentration of 6.6% with the balance oxygen. The structural integrity of the unit was verified by vibration and centrifuge testing. The performance of the molecular sieve unit is discussed in the context of aircraft operating envelopes using both diluter-demand and 100% delivery subsystems.
生成富氧呼吸气体的分子筛方法是陆军-海军-空军联合开发的、用于战术飞机的几种机载制氧（OBOG）候选系统之一。在模拟飞行条件下对一个标称两人使用量的分子筛制氧系统的性能进行了表征。给出了分子筛产生的呼吸气体（氧气、氮气、二氧化碳和氩气）的成分数据，这些数据是进气压力、海拔高度、呼吸气体流速和环境温度的函数。观察到的最大氧气浓度为95%，其余为氩气。在低需求流速以及某些压力和海拔条件下，氩气富集系数超过氧气，氩气最大浓度为6.6%，其余为氧气。通过振动和离心测试验证了该装置的结构完整性。使用稀释需求和100%输送子系统在飞机运行包线的背景下讨论了分子筛装置的性能。
