Which is NOT a major component of turbojet engines?

Explanation:
A turbojet’s propulsion flow relies on four fundamental stages: air entry through the inlet, compression to higher pressure, combustion where fuel mixes with the compressed air, and expansion through the turbine and out the exhaust for thrust. The gearbox assembly is not part of that core energy conversion loop; it’s an accessory drive used to power auxiliary systems like pumps or generators. While some engines include an accessory gearbox, it’s not a core, major component of the turbojet’s propulsion cycle. So the gearbox assembly is not a major component of turbojet engines.
