← ScienceWhich risk significantly increases when exceeding an airplane turbine engine's redline temperature?
A)Accelerated blade creep initiates✓
B)Volumetric locking reduces compression
C)Increased shaft torsion vibration exists
D)Cooling fluid vaporisation accelerates
💡 Explanation
Exceeding redline temperature causes accelerated blade creep because thermally-activated dislocation glide allows plastic deformation; the turbine blades elongate permanently. Therefore blade failure risk increases, rather than fluid vaporization, which happens at lower temperature.
