What component of the Gas Generator Assembly prevents foreign objects larger than 1/4" from entering the engine?

The component that prevents foreign objects larger than 1/4" from entering the engine is the Foreign Object Damage (FOD) screen. This screen is designed to capture debris and prevent it from reaching sensitive engine components, which could lead to significant damage and compromise engine performance. The FOD screen serves as a critical protective barrier during the air intake process, ensuring that only clean air enters the gas generator assembly, thus maintaining the integrity and efficiency of the engine operation.

Other components such as the compressor inlet or air filter may play roles in the air intake process but do not specifically address the prevention of larger foreign objects like the FOD screen does. The exhaust manifold is concerned with the expulsion of exhaust gases, not with the intake of air or the protection from foreign objects.
