New use for squeeze-film damping proposed for turbopump bearings. Damping of axial shaft vibrations improved with properly-designed squeeze-film spring. Capillary-squeeze-film springs damp turbopump shaft axial vibrations. Disks deflect to left and right as pump bearing vibrates. Fluid fills and empties from spaces between disks to damp vibration.
