Abstract
Commercial aircraft fuel tanks, such as the center wing tank or body tanks, can be subject to explosion hazard due to heat balance around the tanks. Various embodiments of the present disclosure reduce the flammability exposure of the fuel tank by drawing cold air from a cold air unit of the aircraft and passing the air to a space proximate the fuel tank, without disrupting the cold air system in flight performance.
