← TechnologyWhich performance loss occurs from excessive stator blade erosion?
A)Compressor stall margin diminishes✓
B)Increased fuel efficiency results
C)Turbine blade creep decreases
D)Combustion chamber pressure decreases
💡 Explanation
As stator blades erode, the shape changes, disrupting airflow, and hence impacting the compressor surge margin due to increased turbulence because energy extraction is less efficient. Therefore, stall margin diminishes rather than improving fuel efficiency which requires optimal flow.
