Your Jet Engine Has a Digital Twin. Here's How It Works

How do jet engines survive gas temperatures hotter than their turbine blades’ melting point? Go inside the GE9X and Rolls-Royce Trent XWB to discover the extraordinary engineering behind modern flight. Some turbine blades are grown as a single crystal. Laser shockwaves help metal resist fatigue cracks. Tiny cooling passages and ceramic coatings protect components from extreme heat. And the air an engine breathes can change how it wears throughout its life. In five minutes, Jamie Lansdell explores how turbofan engines work, why the Boeing 777X’s GE9X and Airbus A350’s Trent XWB use different shaft arrangements, and how salt, desert dust and operating conditions shape engine maintenance. We also explore condition-based monitoring and the predictive modelling behind digital twins: using physics and operating data to understand individual engines. You can see the fan. Now imagine the rest.
