This book was released on 2013-06 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self Contained Oxygen Generators (SCOGs) have widespread use in providing emergency breathing oxygen in a variety of environments including mines, submarines, spacecraft, and aircraft. These devices have definite advantages over storing of gaseous or liquid oxygen. The oxygen is not generated until a chemical briquette containing a chlorate or perchlorate oxidizer and a solid metallic fuel such as iron is ignited starting a thermal decomposition process allowing gaseous oxygen to be produced. These devices are typically very safe to store, easy to operate, and have primarily only a thermal hazard to the operator that can be controlled by barriers or furnaces. Tens of thousands of these devices are operated worldwide every year without major incident. This report examines the rare case of a SCOG whose behavior was both abnormal and lethal. This particular type of SCOG reviewed is nearly identical to a flight qualified version of SCOG slated for use on manned space vehicles. This Investigative Report is a compilation of a NASA effort in conjunction with other interested parties including military and aerospace to understand the causes of the particular SCOG accident and what preventative measures can be taken to ensure this incident is not repeated. This report details the incident and examines the root causes of the observed SCOG behavior from forensic evidence. A summary of chemical and numerical analysis is provided as a background to physical testing of identical SCOG devices. The results and findings of both small scale and full scale testing are documented on a test-by-test basis along with observations and summaries. Finally, conclusions are presented on the findings of this investigation, analysis, and testing along with suggestions on preventative measures for any entity interested in the safe use of these devices.

Download or read book Self Contained Aircraft Oxygen System Volume III Advanced Oxygen Concentrator Stack Development written by John H. Russell and published by . This book was released on 1973 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in solid polymer electrolyte (SPE) oxygen concentrator cell technology in the areas of high temperature operating capability, improved anode catalyst, improved current collector materials, more sophisticated cooling techniques and improved freeze/thaw capability indicated potential weight savings for the self-contained aircraft oxygen system in the order of 80% in the concentrator stack and 63% in the oxygen concentrator system. An eleven-month developmental design and test effort was performed which encompassed cell evaluation, fabrication technique development, full size cell test, 4-cell buildup test, full-size 32-cell stack test, systems analysis, and definition of ancillary components required to support the advanced oxygen concentrator stack. The program resulted in a cell design which offers a 65% stack weight savings (46% on a subsystem basis). (Author).
