Orbital transfer vehicle oxygen turbopump technology. Volume 2: Nitrogen and ambient oxygen testing [PDF]

open access: yes
The testing of a rocket engine oxygen turbopump using high pressure ambient temperature nitrogen and oxygen as the turbine drive gas in separate test series is discussed. The pumped fluid was liquid nitrogen or liquid oxygen.

SSME Long-life Bearings [PDF]

open access: yes
Hybrid hydrostatic/ball bearings for LH2 and LO2 service in turbopumps were studied as a means of improving speed and life capabilities. Four hybrid bearing configurations were designed with emphasis on achieving maximum stiffness and damping.

Thrust and stiffness nomograms for hydrostatic bearing calculations

open access: yes, 1966
The application of hydrostatic lubrication to slideways is now becoming common practice in the machine tool industry. The theoretical basis for determining design parameters for hydrostatic lubrication is well established (Refs. 1 and 2) but one of the practical problems facing the machine tool designer wishing to use this technique is the tedious ...
