Which adverse effect worsens when turbine blade tolerances degrade?

💡 Explanation

Reduced turbine blade tolerances elevate aerodynamic imbalances, inducing uneven pressure distribution. This narrows the compressor's stall margin because the surge risk is heightened, therefore efficiency drops rather than thermal issues, which would require bearing contamination or lubrication failure.
