What effect does insufficient fuel flow have on turbine engine performance?

  1. Can cause engine surging or flameout

  2. Leads to excess oil consumption

  3. Improves overall efficiency

  4. Has no effect on performance

The correct answer is: Can cause engine surging or flameout

Insufficient fuel flow in a turbine engine directly impacts its performance by leading to engine surging or flameout. When fuel flow is inadequate, the combustion process can become unstable. This instability can cause rapid fluctuations in engine pressure and temperature, resulting in surging, which is characterized by a cyclic increase and decrease in thrust. In severe situations, this lack of fuel can lead to flameout, where the combustion process in the engine extinguishes completely. Maintaining appropriate fuel flow is crucial for ensuring a stable and efficient combustion process, which is essential for optimal engine performance.
