description abstract	Description of Driving Event: A characteristic of rotor machinery has been subsynchronous whirl rotor-dynamics, most recently experienced on the SSME. This motion takes the form of whirling or whipping of the flexed rotor at one of the rotor's natural frequencies below the running speed. Both the HPFTP and the HPOTP experience this problem, and a higher performance requirement on these pumps resulted in marginal whirl situations.
