NACELLE AND PYLON
Engine nacelles are streamlined aerodynamic panels used to house and
protect engine components, direct airflow and decrease aerodynamic
drag. The engine nacelles contain the forward and aft firewalls that
comprise the fire zone.
The engine pylon contains a front engine mount, rear engine mount,
firewall, spars, stringers, ribs and skins. Titanium and steel materials are
used on the engine mount and firewalls where a fireproof material is
necessary. The pylons house the Full Authority Digital Engine Control
(FADEC) computers and the fire extinguisher bottles.
