Question 51Gas Turbine - Assistant Engineer

The correct answer is C) To control stator vane angle and GG (gas generator) speed. The main fuel control on the GE LM2500 gas turbine engine is responsible for managing the fuel flow to the engine in order to maintain the desired gas generator speed and stator vane angle. By controlling these parameters, the fuel control system is able to optimize the engine's performance and efficiency across different operating conditions. The other options are incorrect because they do not accurately describe the primary function of the main fuel control. Option A is related to the fuel pump, not the fuel control system. Option B describes the function of the variable stator vanes, not the fuel control. Option D refers to fuel temperature control, which is a separate system from the main fuel control.
