What are the main functions of engine cowlings and baffles?

The main functions of engine cowlings and baffles revolve around streamlining the engine area and managing airflow effectively for cooling purposes. Engine cowlings are designed to create a smooth aerodynamic shape around the engine, which helps reduce drag and improve the aircraft's overall performance. This streamlined design ensures that airflow is directed efficiently around the engine components.

Baffles, on the other hand, play a crucial role in directing the airflow specifically to the engine's critical components in order to maintain optimal operating temperatures. They help ensure that cooling air is directed toward the areas that need it most, thereby enhancing the efficiency of the cooling process. By managing the airflow pattern around the engine, cowlings and baffles contribute to maintaining engine performance and reliability, ultimately supporting safe aircraft operation.
