Civil and military aircraft use nitrogen gas within several components. Tyres are generally inflated with nitrogen gas to prevent deflation caused by oxygen permeating through the tyre wall and reduce the risk of fire.
Undercarriage struts are basically an oil/compressed gas spring. Nitrogen is the inert choice for the gaseous component of the spring. Newer generation of aircraft, with centre wing fuel tanks, require inert gas blanketing due to more stringent safety regulations.
Air from the engine compressor section is fed to a purpose manufactured nitrogen module to provide a continuous stream of gas to blanket the tank.
In addition to on-board nitrogen, autoclaves used in the manufacture of composite material airframe sections are pressurised with nitrogen gas.
Undercarriage and tyre manufacturing / maintenance facilities use nitrogen gas along with escape slide cylinder filling stations.
