Which component in a gas turbine engine can be found in the cold section?

In a gas turbine engine, the cold section refers to areas that are not exposed to the high temperatures generated during the combustion process. The engine inlet is part of this cold section, as it is the initial area where ambient air enters the engine before being compressed and mixed with fuel in the combustor for combustion.

The engine inlet plays a crucial role in ensuring that the correct amount of air is channeled into the engine for efficient combustion. It is designed to optimize airflow to the compressor, enabling the engine to operate effectively. In contrast, components like the combustor and turbine are part of the hot section, where they are directly involved in the high-temperature processes of combustion and energy extraction from the exhaust gases. The exhaust duct also falls into the hot section, as it carries hot gases away from the engine post-combustion. Thus, identifying the engine inlet as a component in the cold section highlights its role in facilitating the intake of cool air for the overall engine function.
