Advancements in Analysis of Hydrostatic Bearings for Cryogenic Turbo Pumps


MAJOR APPLICATION: process fluid film bearings, all-fluid film bearing turbopump technology


Sponsor: Northrop Grumman (USAF USET Program) (2004-2006)

Past sponsors: Rocketdyne, Pratt & Whitney, NASA Glenn RC, NASA MSFC


Objective: To enhance current computational models (developed early at TAMU) to predict

a)     transient response of hydrostatic bearings

b)     start up and shut down response of hydrostatic bearings for turbo pump applications


Status: Known technical issues: pneumatic hammer and dry-friction whirl and whip at cryogenic turbopump start up. Project will deliver computational models for advancing technology to deliver a turbopump free of technical hurdles noted.
