Ever wondered how jet engines survive scorching temperatures—and what happens if you chuck sand into one? This video whisks you from the basics of turbofan operation (and why they’re so massive) through the microscopic world of edge dislocations in nickel-based superalloys. Along the way you’ll tour Rolls-Royce’s precision casting facility, learn how single-crystal blades and gamma-prime phases keep turbines cool, and witness a sand-ingestion test that shows just how tough these engines really are.
Experts from academia and industry break down crystal structures, grain selection, and advanced manufacturing techniques that let jet engines cruise at 600°C+ without melting. Spoiler: sand can cause serious erosion, but clever materials and designs minimize the damage—keeping planes flying smoothly at high heat.
