Abstract

A control moment gyroscope (CMG) includes a stator housing, an inner gimbal assembly (IGA), and a torque motor coupled to the stator housing and configured to rotate the IGA housing about a gimbal axis to selectively generate a desired output torque during operation of the CMG. The IGA includes, in turn, an IGA housing rotatably coupled to the stator housing, a CMG rotor rotatably mounted within the IGA housing, and a spin motor coupled to the IGA housing and configured to rotate the CMG rotor about a spin axis. The CMG rotor includes a rotor shaft, a rotor rim circumscribing the rotor shaft, and a plurality of radially-compliant spokes extending between the rotor shaft and the rotor rim.
