← ScienceWhich outcome impairs a turbojet engine during ascent?
A)Compressor surge inducing flow reversal✓
B)Combustion instability causing thermal runaway
C)Nozzle erosion decreasing thrust efficiency
D)Turbine creep impacting blade clearance
💡 Explanation
Compressor surge disrupts airflow because reduced air density leads to insufficient pressure rise across compressor blades; therefore flow reversals and stalls occur, rather than balanced combustion or turbine damage in properly controlled engines.
