Ever wondered why jet engines don’t melt? This video breaks down how a jet engine works—from air intake and compression through combustion and the massive turbines that drive it—explaining why they have to be so large to handle crazy airflow and heat.
The real magic lies in the blades: they’re made from nickel-based superalloys with a special gamma-prime crystal structure, cast as single crystals and riddled with microscopic cooling channels. Combined with clever design and precision manufacturing at places like Rolls-Royce, these turbines survive 1,000°C+ conditions without turning into molten blobs.
