Why don’t jet engines melt? This Veritasium video breaks down everything from basic engine anatomy and the history of the first turbojet to a behind-the-scenes tour of Rolls-Royce’s precision casting facility. You’ll see how airflow, combustion chambers and massive turbine stages all work together—and get an intro to edge dislocations in metals.
The real secret lies in the insanely strong nickel-based superalloys and single-crystal blades they forge. Special gamma-prime phases, tailored crystal structures and internal cooling channels let these parts survive 1,500 °C-plus, even when you hurl sand at them for fun. Engineering and materials science for the win!
