The structure transfers the forces generated by the Jet engine to the vehicle and provides internal support for the components.
Nacelles
Externally mounted jet engines are enclosed in nacelles that provide the necessary aerodynamic and structural characteristics.
Access doors
Thrust reversing flaps and vanes
Noise abatement
Pylons
The pylon connects the nacelle to the body or wing of the airplane. The pylons may include structural fuses to release the nacelle if the jet engines forces exceed pre determined thresholds to reduce damage to the aircraft.

Containment
The containment structure is usually designed to retain failed blades that detach from the rotor at high speeds. Rotor disks are much more massive than blades and full failures normally cannot be contained in aircraft applications.
