Which risk increases significantly when a turbine operating in a closed Brayton cycle experiences unexpected surge?

💡 Explanation

Compressor blade fatigue failure risks increase because surge introduces high-frequency pressure oscillations that cause resonant blade excitation, thus accelerating fatigue crack propagation. Therefore, blade failure is amplified rather than combustion or performance changes which need sustained different conditions.
