Why don’t jet engines melt? Veritasium dives head-first into the anatomy and history of jet engines, showing how turbines crank out insane thrust without turning into molten metal. You’ll get a backstage pass to Rolls-Royce’s precision casting facility, learn why nickel superalloys (hello, gamma-prime!) and single-crystal blades laugh in the face of 2000°F temperatures, and see how crystal structures and dislocation mechanics hold everything together.
Along the way, Derek Muller and pals chat with top experts from Cambridge and Ruhr University, toss sand at a running engine (spoiler: it’s bad news), and unpack the microstructural magic that keeps your next flight cool, calm, and far above the melting point.
