What is the primary function of the accessory gearbox assembly?

• A. To drive auxiliary components such as the fuel pump, generators, and starting motor
• B. To house the main combustor
• C. To support the turbine shaft
• D. To regulate fuel flow to injectors

Answer: (A)

The accessory gearbox assembly’s main job is to provide mechanical drive to the engine’s auxiliary components. It’s driven by the high‑pressure (HP) spool and powers items like the fuel pump, generators, and starting motor. These components are essential for starting the engine, supplying fuel, and generating electrical power during operation. It isn’t where the combustor is housed, it doesn’t support the turbine shaft, and it doesn’t regulate fuel flow to injectors (that’s handled by the fuel control system and injectors). So the gear box’s primary function is toDrive those auxiliary components.
