Why Jet Engines Survive by Letting a Layer Fail First (Thermal Barrier Coatings Explained)
The world’s most powerful jet engines — like those powering the largest wide-body aircraft — operate in gas temperatures reaching 1,500 to 1,700°C. Yet the metal turbine blades inside begin to lose long-term strength above roughly 1,050 to 1,100°C. That gap should destroy them.
So engineers didn’t invent a magical metal.
They changed what takes the heat.
Jet engines survive extreme heat not by eliminating failure — but by choosing what fails first.
