Abstract:
1. A control moment gyroscope (CMG), comprising: a stator housing; an inner gimbal assembly (IGA), comprising: an IGA housing rotatably mounted to the stator housing; a CMG rotor rotatably mounted to the IGA housing, the CMG rotor comprising: a rotor shaft having a length; a rotor rim circumscribing the rotor shaft; and a plurality of radially-compliant spokes extending between the rotor shaft and the rotor rim, each radially-compliant spoke including an outer spoke end and an inner spoke end, the inner spoke end having an axial height that is closer to the length of the rotor shaft than to the axial height of the outer spoke end; wherein the plurality of radially-compliant spokes are integrally formed with the rotor shaft and the rotor rim as a single machined piece; and a spin motor coupled to the IGA housing and configured to rotate the CMG rotor about a spin axis; and a torque motor coupled to the stator housing and configured to rotate the IGA housing about a gimbal axis to generate a desired output torque during operation of the CMG.
