Jet Propulsion/Rotors
(Redirected from Jet Propulsion/Rotors/)
The moving parts of the jet engine. The turbomachinery blades are mounted on a number of Rotors.
disks edit
The disks provide structural fixing and resist the radial and axial forces generated by the airfoils in the fans. compressors, turbines.
