Collins Aerospace’s fuel tank inerting systems improve aircraft safety by reducing oxygen in the fuel tank to prevent combustion, even if a spark is present.

Our inerting systems reduce the volatility of the ullage, or air volume above the fuel, in the aircraft fuel tank. As fuel is consumed during flight, the fuel level in the tank is lowered and the remaining oxygen in the ullage is replaced by non-flammable inert gas.

Membrane gas separators are an advanced technology that reduces the oxygen concentration of the air entering the fuel tank. Precise pressure, temperature and oxygen concentration controls are also responsible for optimizing performance over the various phases of the flight envelope.

The system greatly enhances flight safety for commercial and military aircraft. Advances in technology and design enable systems that are highly reliable, lightweight and efficient.
