Which outcome occurs when a gas turbine engine operates at excessive inlet temperature?

A)Reduced NOx emissions through thermal decomposition
B)Increased turbine blade creep and deformation
C)Improved fuel efficiency due to higher compression
D)Decreased surge margin within the compressor

💡 Explanation

When inlet temperature exceeds design limits, turbine blade creep occurs as intermolecular forces weaken under the increased thermal load, accelerating plastic deformation. Therefore increased blade deformation results, rather than reduced emissions, improved efficiency, or increased surge margin which are affected by combustion mixtures and flow separations.
