Why Don’t Jet Engines Melt? dives into how modern turbines run at temperatures hotter than their own melting points. Starting with a quick primer on airflow, compression and combustion, it walks you through the first jet engines, then takes you inside Rolls-Royce’s precision casting facility to see exactly how turbine blades are made.
The real magic is in the materials: nickel-based superalloys riddled with gamma-prime precipitates, grown as single crystals and drilled with micro-cooling channels, plus smart crystal–grain selection to block edge dislocations. Throw in real-world tests (like hurling sand at spinning blades) and you’ve got a recipe for components that don’t just survive, but thrive, in extreme heat.
