A new spherical Gas Gyrobearing configuration is presented. The static performance is evaluated for general eccentricity, and data is presented for load capacity, gas flow rate and error torque, over a range of eccentricities and gas feed pressures. The dynamic stability of the rotor about an equilibrium point, assuming small perturbations, is analyzed using the step-jump method. Finally, a nonlinear path simulation was performed, by simultaneously solving the Reynolds equation and the rotor’s equations of motion.
