According to the load elastic distortion formula of theory for elasticity shell
making use of small distortion independent action and synthesis theory
built superposition formula of surface distortion produced by radial load and centrifugal load for ESG hollow Be rotor. And built up a long spherical hollow Be rotor with long-polarized and short-equatorial. The long spherical hollow Be rotor designed by radial deformation have a better sphericity in high-speed rotation. Finally
used a sample to show the long spherical hollow rotor's design
