← ScienceWhich risk increases when cooling systems within a jet engine compressor stall?
A)Fuel injection system failure
B)Blade resonance and fatigue✓
C)Decreased combustion chamber density
D)Increased propulsive efficiency loss
💡 Explanation
Blade fatigue increases because temperature gradients establish complex thermal stresses that amplify the resonance frequency with the compressor. Therefore, blade resonance and fatigue, rather than efficiency losses, drives catastrophic failure because cooling impacts the harmonics.
