Solar Fan

Ignited by the setting Sun on A319 CS-TTR's tail, the CFM56-5B fan blades glow as if they marked the entrance to a blast furnace. This shot clearly reveals the high by-pass nature of the engine in which only a small portion of the air that goes through the fan disk, about 1/6^th , has access to the engine core via the low pressure compressor. The rest of the air remains cold and is shot out of the rear of the engine by the fan producing the vast majority of total thrust.
