Jet Propulsion/Rotors

The moving parts of the jet engine. The turbomachinery blades are mounted on a number of Rotors.

disks
The disks provide structural fixing and resist the radial and axial forces generated by the airfoils in the fans. compressors, turbines.

shafts
Shafts connect the functional parts and transfer forces from turbines to fans and compressors and to bearings.

bearings
The rotors are supported on bearings.

Functional requirements
Loading, Overloading, service life, lubrication

Seals
The pressure differentials between different rotating parts are maintained by seals.
