Damping Seals Would Help Support Turbopump Rotor
Abstract
Report describes engineering study of proposed use of damping seals as major load-carrying members of high-pressure-oxygen turbopump of Space Shuttle main engine. Incorporated into bearing packages at preburner-pump and turbine-end locations on pump rotor. Concept motivated by need to increase operating lives of ball bearings supporting rotor by relieving them of damaging transient lateral loads.
