← TechnologyWhich consequence results when rapid turbine shaft deceleration occurs?
A)Compressor stall initiates upstream airflow reversal✓
B)Turbine blade creep rate decreases gradually
C)Combustion chamber pressure remains stable
D)Fuel injector nozzles sustain uniform flow
💡 Explanation
Compressor stall can occur following rapid deceleration due to a surge where pressure builds and airflow begins moving backwards, rather than smoothly onward, because decreased shaft speed lowers momentum; therefore, the incoming momentum opposes forward flow; rather than other effects limited by flow disruptions.
