摘要
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.
