Claim Text:
1. A control moment gyroscope (CMG), comprising: a stator housing; an inner gimbal assembly (IGA), comprising: a torque motor coupled to the stator housing and configured to rotate the IGA support structure about a gimbal axis to selectively generate a desired output torque during operation of the CMG; wherein the monolithic CMG rotor comprises a rotor rim, a rotor shaft, and a plurality of torsionally-stiff radial spokes integrally joined to the rotor rim and the rotor shaft as a single piece; and wherein each of the plurality of torsionally-stiff radial spokes is joined to the rotor shaft at a first spoke-shaft joinder interface and at a second spoke-shaft joinder interface, the first spoke-shaft joinder interface located closer to a first end of the rotor shaft than to the gimbal axis, and the second spoke-shaft joinder interface located closer to a second opposing end of the rotor shaft than to the gimbal axis.
