Which consequence results when excessive heat input skews an ideal Brayton cycle operation?

A)Reduced turbine blade creep lifetime
B)Increased compressor efficiency ratio
C)Lower nitrogen oxides emissions formed
D)Decreased fuel pump cavitation risk

💡 Explanation

Excessive heat input elevates turbine temperatures which accelerates grain boundary slip, because the resulting accelerated creep deformation rate decreases predicted structural lifetime, therefore shortening practical service before failure, rather than impacting compression or emissions at the low temperature compressor stage.
