How a Jet Engine Actually Works — The Fire Doesn't Push You

Next: the carrier film premieres Thursday Nov 12, 7:30 PM —    • 0 to 165 mph in 2 Seconds — Too Short to Fly   Almost all of the thrust from a modern jet engine comes from the fan at the front — not from the fuel burning behind it. The core exists mostly to turn that fan. This video follows one parcel of air all the way through a turbofan: the intake that slows it down to raise its pressure, the fan that sends most of the air straight past the core, dozens of compressor stages that make it scorching before any fuel arrives, the flame that never goes out, and the turbine blades that survive above their own melting point by wearing a film of air bled from the compressor.
