Cobham, a world leader in gas separation and high pressure gas
management, has been developing and delivering fuel tank inerting
systems and subsystems for 30 years. With systems on more than
3,000 aircraft and over 5 million flight hours, Cobham possesses
the unique technical ability to design an optimally sized and
configured On-Board Inert Gas Generating System (OBIGGS) using
either Hollow Fiber Membrane or Pressure Swing Adsorption
technology. Cobham OBIGGS are designed for both military and
Reducing the risk of fuel tank explosion
The risk of fuel tank explosions is caused by the presence of
all three of the following elements, known as the "fire
triangle": the fuel-rich vapors (or ullage) that build up in
the fuel tank, an ignition source, and oxygen from atmospheric
air. Cobham's OBIGGS substantially reduces the risk of
explosion by displacing the oxygen in the fuel tank with
non-flammable nitrogen-enriched air.
Unique pedigree with diverse mission profiles and proven
Drawing on unparalleled experience in designing fuel tank
inerting systems for a broad range of applications, from military
attack helicopters to large commercial aircraft, Cobham can develop
OBIGGS solutions to accommodate a wide range of mission profiles.
Cobham, offering system solutions from the bleed air tap to fuel
tank distribution for any aerospace platform, is the only company
that can provide fuel tank inerting systems featuring either Hollow
Fiber Membrane (HFM) or Pressure Swing Adsorption (PSA) technology.
Cobham's proven Air Separation Modules can be found on military and
commercial aircraft all over the world.
Optimisation through integration
Cobham optimises fuel tank inerting systems by integrating
multiple assemblies and components to achieve the optimal system
performance level. Working with customers early in the design
phase to help define requirements and system architecture, Cobham
develops precision temperature, pressure and oxygen sensing
components to give you the highest-performance, safest, most
robust, lowest maintenance solution.
