Application of Flow and Stability Theory to the Design of Externally Pressurized Spherical Gas Bearings

Application of the flow theory of Laub and Norton [1] and the stability theory of Licht, Fuller, and Sternlicht [2] is made to the design of externally pressurized spherical gas bearings. Analytical results are presented in the form of “stability maps” (stability limits) and were confirmed by experimental data. The double-valuedness of stable loading for a constant supply pressure is predicted. The design procedure presented appears to be a dependable method for assuring stable operation of spherical gas bearings.
