Why Don’t Jet Engines Melt?

This video unpacks how jet engines work and why their hottest parts don’t turn to goo. You’ll get a whirlwind tour through engine basics, the jaw-dropping size of modern turbines, the evolution of jet propulsion and a peek inside Rolls-Royce’s precision casting facility.

It then dives into the superalloy magic—gamma prime strengthening, crystal structures and single-crystal blade manufacturing—that lets turbine blades survive temperatures well above what you’d expect. Along the way you’ll meet experts, see animated microstructures and learn why sand in an engine is way more dramatic than you’d think.
