Permeability and dynamic elastic moduli of controlled porosity ultra-precision aerostatic structures [PDF]
, 2014 Porous ceramic aerostatic bearings enable precise and smooth motion and improved stiffness compared with widely used orifice restrictor bearings. However, the processing techniques so far used are too complex or rely in lowering the sintering temperature

Processing and fluid flow characteristics of hot isostatically pressed porous alumina for aerostatic bearing applications [PDF]
, 1996 Despite their well known superior load and stiffness characteristics, the wide-spread use of porous aerostatic bearings in preference to other bearing types has been hampered by difficulties in controlling the permeability of the porous material during

International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.The finite element method was used in this study to explore the impact of surface roughness and thermal characteristics on slider bearings with non‐Newtonian power‐law fluid flow lubricant. One‐dimensional transverse and longitudinal surface roughness models were considered under the stochastic assumption that roughness has a Gaussian random ...

Instability studies of an 'O'-ring flexibly supported, gas bearing, mounted, cool air unit. [PDF]
, 1990 A Cool Air unit (C. A. U. ) is powered by air bled from the engine and supplies cool air to the avionics and cockpit of the aircraft. Essentially a small turbo machine, the rotor is mounted upon two plain (gas) air bearings, which are flexibly ...
