Vulnerability Methodology and Protective Measures for Aircraft Fire and Explosion Hazards. Volume 3. On-Board Inert Gas Generator System (OBIGGS) studies. Part 3. Aircraft OBIGGS Designs
Abstract
The primary performance of on-board inert gas generator systems (OBIGGS) in laboratory and simulated flight tests indicated these systems were suitable for aircraft implementation. Accordingly, preliminary design studies were made to determine the requirements for aircraft OBIGGS installations and to compare the OBIGGS with other fire protection systems. This report presents a technique for establishing the inert gas required for the design mission and discusses OBIGGS installations on a C-5B and an ATF airplane. Both permeable membrane (PM) and molecular sieve (MS) OBIGGS were considered for both airplanes. When all factors were considered the performance and penalties of the PM and MS OBIGGS on these airplanes was comparable. When compared with other fire protection systems, the OBIGGS had significant weight advantages over foam systems and significant cost and logistics advantage over Halon and liquid nitrogen systems.
