The engine nacelle encases the jet engine compressor, combustor and turbine. A nacelle fire is typically a turbulent diffusion flame stabilized behind an obstruction in a moderately high speed air flow. The most likely source for a fire in the nacelle are leaks in the fuel lines carrying jet fuel or hydraulic fluid, that can feed the fire either as a spray or as a pre-vaporized gas. Temperatures as high as 150 deg C are common in normal operating engine nacelles.
