Question 89Gas Turbine - 1st Asst/Chief70% to pass
What is the primary function of the main fuel control on the GE LM2500 gas turbine engine?
AI Explanation
The correct answer is B) To control stator vane angle and GG speed.
The main fuel control on the GE LM2500 gas turbine engine is responsible for regulating the fuel flow to the engine in order to maintain the desired gas generator (GG) speed and stator vane angle. This ensures the engine operates at the optimal efficiency by adjusting the fuel delivery based on the engine's operating conditions.
The other answer choices are incorrect because: A) the fuel temperature is typically controlled by a separate system, C) the fuel pump inlet pressure is not directly controlled by the main fuel control, and D) the main fuel control does not directly regulate the bleed air discharge, which is usually handled by a separate control system.
