Available in PDF, EPUB and Kindle. Book excerpt: An onboard oxygen generating system (OBOGS) has been developed by Clifton Precision, according to U.S. Air Force School of Aerospace Medicine (USAFSAM) specifications, for a flight test demonstration in the F-16A aircraft. Prior to actual flight test, the system was certified at the USAFSAM as described in this report. Laboratory testing consisted of manned and unmanned tests at ground level, at altitude, during rapid decompressions, and during acceleration loading. System hardware consisted of a molecular sieve concentrator, breathing-gas regulator, selector valve, product gas composition controller, backup oxygen supply (BOS), and a breathing mask. These components replace current liquid oxygen (lox) components and eliminate the need to service lox converters, resulting in faster aircraft turnaround time, increased safety, and decreased cost. Laboratory test results indicated that the F-16A OBOGS was adequate for flight test and that the breathing-gas composition was physiologically capable of preventing hypoxia and reducing the occurrence of atelectasis. Furthermore, the OBOGS provided considerably less breathing resistance than current lox systems. The concentrator and BOS provided the ability and redundancy to protect the pilot throughout the operational envelope of the F-16A. (Author).

Book excerpt: There have been an increasing number of hypoxia-type incidents, especially in the F-22 Raptor aircraft, that may be related to on-board oxygen generating systems (OBOGS). This report details recommendations made by the USAF Scientific Advisory Board's Aircraft Oxygen Generation (AOG) Quicklook Study to help mitigate this safety problem. The AOG Study Panel received a large number of briefings and perspectives on various aircraft OBOGS standards and designs in general; the F-22 and F-22 OBOGS in particular, pilot physiological performance under various conditions, and many other related issues, from within and outside the United States Government. The Study Panel evaluated the current F-22 oxygen system, OBOGS and life support systems in general (including contaminants that could affect OBOGS operation), and human responses to high altitude rapid cabin altitude changes/rapid decompression environment with less than 90% oxygen. It also assisted with: F-22 return-to-fly criteria as requested, evaluation of Air Standards, review and validation of performance-based acquisition programs and associated risk analysis protocols, and with reviewing and revalidating aircrew flight equipment affiliated with OBOGS-equipped aircraft.

This book was released on 1978 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the high support costs, increase in aircraft down time, and hazards associated with the use of liquid oxygen, development has been progressing on On-Board Oxygen Generation Systems which have the capability of meeting the requirements of a two man open loop breathing schedule. An evaluation program was conducted on an oxygen generator utilizing the molecular sieve concept of nitrogen absorption. The system was developed to establish unit performance in the environment anticipated during in flight operation. Oxygen concentration has been evaluated as a function of inlet air pressure.

Available in PDF, EPUB and Kindle. Book excerpt: This report sets forth the findings of a test and evaluation (man rating) of the molecular sieve oxygen generation system developed for the 1B Long Range Combat Aircraft. A series of unmanned and manned tests, covering the range of aircraft operating conditions, were conducted on a duplicate of the aircraft breathing system which was assembled in an environmental chamber. The control variables were cabin and aircraft ambient pressure, inlet air temperature and pressure, cabin temperature, and demand flow; and the dependent variables were oxygen concentration, pressure swings in the mask, and time required for backup oxygen to reach the crew after rapid decompression (RD). Oxygen output met or exceeded specification requirements for all but two test points. Under nominal aircraft operating conditions and the maximum average demand flow of 160 liters per minute (1pm), oxygen concentration fell slightly below specification requirements at 25,000 and 28,000 ft cabin altitude. These discrepancies are not considered significant (i.e., will not compromise crew safety), because the probability is very slight that a demand flow rate as high as 160 1pm will ever occur (tests showed that 6 persons taking moderately heavy, rapid breaths generated 135 1pm average demand at ground level). Furthermore, the oxygen partial pressure, in the worst case, was equivalent to breathing air at only 4,000 ft pressure altitude.

Available in PDF, EPUB and Kindle. Book excerpt: The Navy/Air Force Oxygen Generating System (NAOGS) program is a joint effort between the Air Force and the Naval Air Development Center to develop a 2-man onboard oxygen generator for tactical aircraft. One of the proposed systems is based upon reversible sorption of oxygen from aircraft engine bleed air using fluomine, a cobalt chelate. The NAOGS fluomine system was manufactured by Garrett/AiResearch Division, Torrance, California. The USAF School of Aerospace Medicine performed man-rating of the NAOGS-fluomine unit prior to flight test by the U.S. Navy. The experimental protocol at USAFSAM consisted of both unmanned and manned testing, during which the product oxygen was monitored for quantity, purity, and trace contaminant content. Man-rating consisted of actual flight simulations with 2 test subjects at four different altitudes for periods up to 2 hours while breathing the product oxygen. The NAOGS, for the most part, performed adequately during both manned and unmanned testing. The exceptions were a lower than specification oxygen production rate and a short-term drop in oxygen purity during each bed switching cycle. These shortcomings are discussed in the context of the forthcoming flight test program. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The molecular sieve method of generating an enriched-oxygen breathing gas is one of three candidate on-board oxygen generation (OBOG) systems under joint Navy-Air Force development for application in tactical aircraft. As part of this program, the performance of a nominal 2-man-capacity molecular sieve oxygen generation system (MSOG) was characterized under simulated flight conditions. Data were given on the composition (oxygen, nitrogen, carbon dioxide, and argon) of the MSOG-generated breathing gas as a function of inlet air pressure, altitude, and gas flow rate. The maximum oxygen concentration observed was 95% with the balance argon. Under certain conditions of pressure, altitude, and flow, the argon enrichment factor exceeded that of oxygen giving a maximum argon concentration of 6.4% with the balance oxygen. The performance of the MSOG was discussed in the context of aircraft operating envelopes using both diluter-demand and 100% delivery subsystems.
