How does a jet engine actually work?

You feel the roar, the powerful whine, and the incredible force pressing you back into your seat. A jet engine is one of the most powerful machines ever built, but how does it actually work? In this episode, we go inside the engine to demystify the magic of flight. We'll follow the air on its journey through the four critical stages—suck, squeeze, bang, and blow—and explore the amazing variations of the jet engine family, from the efficient turbofans on airliners to the earth-shaking power of an afterburner on a fighter jet. You'll learn how engineers use impossible materials and ingenious cooling tricks to stop these engines from melting, and how a machine with no moving parts could power the future of hypersonic flight.
