Improved rotor response of the uprated high pressure oxygen turbopump for the Space Shuttle Main EngineA means of eliminating the subsynchronous rotor whirl encountered during the development testing of the high-pressure oxygen turbopump of the Space Shuttle Main Engine is proposed. The rotor response is improved by reducing the pump end bearing loads and adding damping between the rotor and housing. In the present method, the impeller annular seals are converted into damping seals and the second rotor critical speed is increased due to the added stiffness of the seal conversion and the stiffening of the rotor shaft.
