During the 1970s, the development of onboard oxygen generation systems (OBOGS) progressed through ground and flight test phases to the point where a second-generation concept is now production qualified and additional alternatives are being evaluated. This paper reviews the development of OBOGS and assesses the current state of the art of these systems. High-purity fluomine systems, developed for flight demonstration and qualified for production application, are discussed. Development of enriched air molecular sieve systems for laboratory and flight applications is described, along with a recent study of a permeable membrane-based aircraft oxygen enrichment concept. Capabilities and characteristics of the various OBOGS concepts are compared, showing the greater compliance of high-purity fluomine systems with the current oxygen military standards while noting the advantages of the reduced interface complexity of enriched air systems. Recommendations for future OBOGS development are presented, emphasizing the need to coordinate the development of specifications and hardware so the optimum compromises between physiological requirements and engineering feasibilities can result in OBOGS that best satisfy the metabolic needs of aircrew members.
在20世纪70年代，机载制氧系统（OBOGS）的开发历经地面和飞行测试阶段，发展到如今第二代概念已具备生产资质，且正在评估更多替代方案。本文回顾了OBOGS的发展历程，并评估了这些系统的当前技术水平。文中讨论了为飞行演示而开发并具备生产应用资质的高纯度氟化物系统。描述了用于实验室和飞行应用的富氧空气分子筛系统的开发情况，以及最近对一种基于渗透膜的飞机氧气富集概念的研究。比较了各种OBOGS概念的能力和特性，表明高纯度氟化物系统更符合当前的氧气军事标准，同时指出了富氧空气系统接口复杂性降低的优点。文中提出了未来OBOGS开发的建议，强调需要协调规范和硬件的开发，以便在生理需求和工程可行性之间达成最佳折衷，从而开发出最能满足机组人员代谢需求的OBOGS。
