← ScienceWhich outcome arises when exceeding the maximum turbine inlet temperature in turbojet engine?
A)Increased thrust due to mass flow
B)Blade creep due to reduced cooling✓
C)Fuel inefficiency from excess bypass
D)Compressor stall from back-pressure
💡 Explanation
When maximum turbine inlet temperature is exceeded, blade creep occurs because the superalloy mechanical strength weakens under extreme heat and centrifugal stress, causing plastic deformation. Therefore blade creep results, rather than increased thrust, inefficiency, or stall, which result from other operating conditions or malfunctions.
