The video dives into how jet engines actually handle temperatures above the melting point of metal by using advanced nickel-based superalloys, single-crystal turbine blades, cooling channels and protective coatings. It starts by breaking down how a jet engine works, why they’re so huge, and the evolution from the first jet engines to modern precision casting at Rolls-Royce factories.
Along the way you learn about the microstructure of gamma prime superalloys, edge dislocations, grain boundaries, and how precise crystal orientation and internal air channels keep turbine blades just cool enough. You also get a behind-the-scenes look at the manufacturing process, expert insights from Cambridge and industry pros, and some fun demos (including throwing sand into a running engine).
