More about Nacelle
A nacelle guides airflow around and, where appropriate, into the engine installation. Its components can include intake and exhaust structures and access panels.
It is distinct from the engine itself. Its shape and arrangement affect airflow, maintenance access and the integration of the powerplant with the airframe.
