Since pilots have had the need to breathe at high altitudes, Carleton Life Support Systems Inc. has been there for them, providing oxygen enriched air and committing to the safety of their mission.
Carleton Life Support Systems is a world leader in the application of air separation technology for aviation applications and in the design and manufacture of miniature sterling cycle cryogenic coolers. Bendix Aviation founded the company in 1951 and the sold the facility to Litton Industries in 1982. Northrop Grumman Corporation acquired Litton Industries in 2001 and then in August 2003, divested the Life Support division, based in Davenport, IA, to Cobham plc, Dorsett, United Kingdom. Carleton Life Support is now part of the Carleton Technologies family of companies owned by Cobham.
Since its inception, Carleton Life Support has continually challenged its employees by encouraging forward thinking and maintaining its leadership role in advanced technology for military and commercial products. Life Support has developed an attention for details and prides itself on its rich history and reputation for excellence. Today, that persistence and innovation has transformed Carleton Life Support into a world-class operation that is on the forefront of superior new technology and continued market leadership.
NC1147 On-Board Inert Gas Generating System (OBIGGS)

Risk - Combustion of oxygen rich fuel vapors in the fuel tank ullage, leading to explosion and fire. The risk is increased in helicopters due to sloshing of fuel, fuel tank vibration, and inherent vulnerability to enemy ground fire.

Solution - OBIGGS increases aircraft survivability and crew member safety by inerting the aircraft fuel system against ballistic threats up to and including 23mm HEI (High Explosive Incendiary) rounds and environmental threats such as lightning and static discharge. OBIGGS inerts the aircraft fuel system by providing a continuous generated flow of nitrogen enriched gas into the fuel tanks and thus eliminates the combustible fuel/air ullage mixture.

Adaptability - This OBIGGS is being produced for the MH-47E Chinook and is designed to accommodate your specific attack, utility, cargo and reconnaissance helicopter inerting and fuel system ballistic tolerance requirements.

Features:
  • Built-in test capability.
  • Integral inlet air filter, system controller, and oxygen monitor.
  • Quality product gas is produced immediately on start-up.
  • Requires no ground support equipment.
  • Compared to foam, assures increased usable fuel and easy access to fuel tanks by ground crews.
  • Maintenance and life cycle costs are both significantly lower than other inerting alternatives.
