← ScienceWhich risk increases when a turbojet engine's intake airflow is distorted?
A)Compressor surge and blade stall✓
B)Elevated exhaust gas temperature
C)Fuel injector nozzle clogging
D)Increased turbine blade creep rate
💡 Explanation
Compressor surge and blade stall risk increases due to disrupted airflow. Distorted airflow causes uneven pressure distribution and decreased stall margin across the compressor stages triggering aerodynamic instability and flow reversal because stall occurs. Therefore 'A' is accurate, rather than injector clogging or turbine creep, which result from thermal stresses.
