Advanced Scroll Compressor for Next Generation Cryocoolers
Agency / Branch:
DOD / MDA
Active cooling at 10-35 K has been identified as a key technology for future space tracking and surveillance operations which utilize doped silicon infrared sensors. The Brayton-cycle cryocooler has been recognized as an advantageous method for providing efficient, low-temperature cooling onboard a spacecraft. One significant technology gap specific to recuperative-cycle cryocoolers is the availability of a long-life compressor capable of delivering the pressure ratio and flow rate necessary to circulate and efficiently expand the cooling fluid. Technology Applications, Inc. (TAI) proposes to advance cryocooler capabilities by developing a high-efficiency, oil-free scroll compressor having a potential operating lifetime of up to ten years in collaboration with Air Squared, Inc. Feasibility of a space-qualifiable scroll compressor will be established with a work plan focused on: long-life tip seals that limit leakage and contamination, meeting the working fluid contamination requirements of a cryocooler, and developing a thermal interface for operation in a space-based system. We propose to drive this technology toward long-life cryocooler applications for airborne, space flight, and ground-based systems for both government and commercial customers.
