← ScienceWhich risk increases when a jet engine turbine's blades exceed maximum temperature?
A)Blade creep rate accelerates rapidly✓
B)Turbine efficiency dramatically increases
C)Compressor stall becomes greatly reduced
D)Fuel consumption linearly stabilizes slowly
💡 Explanation
Increased temperature accelerates **thermally activated creep** because it raises the diffusion rate of atoms, therefore causing plastic deformation and accelerated failure, rather than increasing efficiency or affecting compressor dynamics, which depend on aerodynamics.
