Abstract : The Federal Aviation Administration is investigating the use of alternate technologies for fire suppression aboard aircraft. A system was built using hollow fiber permeable selective membranes to separate air into its two major constituent gases, namely oxygen and nitrogen. System performance was characterized with regard to pressure, flow, temperature, and their affects on the nitrogen enriched stream. Test results indicate that nitrogen stream purity varies directly with air pressure and temperature and inversely with flow rate. The test data also indicate that there is an optimum combination of flow and nitrogen purity for inerting a fixed volume. p3
