← TechnologyWhich consequence results when aeration disrupts a jet engine's fuel control valve?
A)Lean combustion and engine surge✓
B)Increased turbine blade creep
C)Nozzle guide vane thermal shock
D)Elevated fuel pump head pressure
💡 Explanation
Lean combustion and engine surge results from aeration introducing gas bubbles, which causes the fuel control valve to deliver less fuel than mandated by "metering", because the volume displaced includes air, therefore, air-fuel mixture leans rather than being optimized, potentially creating uneven burn.
