Advanced Component Technology for Next Generation Cryocoolers
Agency / Branch:
DOD / MDA
The DoD SBIR solicitation is seeking to identify innovative technology for next generation cryocooler systems for infrared sensing technologies and spacecraft cooling applications. Successful development of these novel technologies will result in (1) lowering the cost and risk of cryocoolers, (2) increased reliability and lifetime, and (3) producibility of cryocooler systems. JRD, in conjunction with Raytheon, is working on the development of two related solid-state cryocooler designs, one based on pulse tube technology and another on a Joule-Thompson cycle. These designs are inherently extremely low in vibration, which is critical for image jitter minimization, and structurally robust, essential for launch survivability. Furthermore, initial calculations predict that efficiency potential of these concepts is competitive with present day cryocooler technology. In this project, we will investigate cryocooler systems, both utilizing extremely low vibration (< 1mN) solid state compressors (SSC) to form highly reliable, low cost, long life cryogenic systems for space applications. As part of the study, we will evaluate the design implications of the two cryocooler systems operating with a SSC to define a practical design that provides all of the targeted reliability and performance advantages using one or both of the two approaches.
