Jet Propulsion/Structures

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.

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.

Service forces
TO Cruise Landing

Failure forces
Turbine failure Fan blade failure Bird Impact Out of balance

Compressor
Axial, Radial

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.
