Abstract
The study provided a detailed description of a two-man molecular sieve oxygen generating (MSOG) system and evaluated the performance characteristics of the system at ground level and altitude. The system was designed by Normalair-Garrett Ltd to provide adequate oxygen-enriched breathing gas for two crewmembers up to a cabin altitude of 25,000 feet. The study consisted of operating the MSOG system through a range of product gas flowrates at ground level and various aircraft/cabin altitude combinations in order to determine if the system was as efficient as designed. The results indicated that up to a cabin altitude of 8,000 feet and an aircraft altitude of 23,000 feet, the system is capable of providing sufficient oxygen-enriched breathing gas for two active crewmembers. The maximum oxygen generating capability of the system was 95%, which is the present limit for molecular sieve oxygen concentrators (MSOCs). TRUNCATED
