Why don’t jet engines melt? Derek Muller takes us on a whirlwind tour from the basics of how a jet engine works and why they’re so huge, to the microstructure secrets that keep turbine blades from turning into molten pools. We get a peek inside Rolls-Royce’s precision casting, learn about edge dislocations and nickel-based superalloys (hello gamma prime!), and see how single-crystal blades and clever internal cooling passages let parts survive scorching gas flows.
Packed with history (the first jet engine!), mind-bending crystal growth animations, and even a “sand in the engine” demo, this video covers everything from materials science to manufacturing wizardry. Plus, shout-outs to sponsors, researchers, and the entire production crew that made it all possible.
