Abstract: A system includes a device, a support structure, and a flexure bearing configured to connect the device to the support structure. The flexure bearing includes an outer hub and an inner hub, where the hubs are configured to be secured to the support structure and to the device. The flexure bearing also includes multiple sets of flexure arms connecting the outer hub and the inner hub, where each set of flexure arms includes symmetric flexure arms. The flexure bearing further includes multiple bridges, where each bridge connects one of the flexure arms in one set of flexure arms to one of the flexure arms in an adjacent set of flexure arms.

Abstract: Components within a cryocooler are scaled and/or configured for operation at a CMG operating frequency (e.g., 100 Hz) rather than at 30 to 70 Hz, matching the exported disturbances of control moment gyroscopes on the same platform and reducing line-of-sight jitter for electro-optic infrared focal plane array sensors. The smaller piston working volume and other reduced component sizes allow the cryocooler to be smaller and lighter than designs operating at lower frequencies. Combined with an advanced regenerator suitable for the higher frequency operation, the cryocooler has improved cooling efficiency over such lower frequency designs.
