On Board Oxygen Generating Systems - Other Technologies
This AIR provides an overview of several emerging technologies for on board oxygen generation. It complements AIR 825/6, which covers pressure swing adsorption using zeolite molecular sieve beds to concentrate and separate oxygen from atmospheric gases. Topics covered here include use of dense ion conductive ceramics, electrolysis of water, high pressure chemical generation, membrane separations, and use of carbon based molecular seive beds.
Rationale: The series of AIR 825 slash documents (825/1 through 825/14) comprise an introduction to the subject of aircraft oxygen equipment. They brief the reader on basic principles and provide a foundation from which to understand more advanced and detailed information. Although the technologies described in this document have not yet reached the same level of maturity and acceptance as others covered in the series, the reader will receive basic information allowing recognition of potential benefits in possible future applications of these technologies.
