Abstract
In the mid-1990's, DRS Infrared Technologies began an effort to extend the application of flexure spring technology into cryogenic coolers being supplied for tactical military applications. Previous papers have explored the design challenges and reported performance, life, and environmental testing results. In addition, DRS has now extended the flexure spring design into cryocoolers designed to operate in high ambient temperature ranges previously deemed too severe for linear drive cryocoolers. This paper discusses the design considerations that must be addressed at these high temperatures. Performance and test results for one such cooler, designed for a U.S. Navy threat warning sensor, with cryocooler case temperatures of 120°C, are presented.
