Which outcome results when the Brayton cycle efficiency tops-out in a gas turbine powerplant?

💡 Explanation

Vanes overheat because peak temperatures occur at optimal efficiency for the Brayton cycle; therefore, enhanced hot corrosion of airfoils results rather than surge margin decreases or fuel instabilities, since those are compressor-specific failures.
