Abstract

Linear drive Stirling cryocooler designs for tactical infrared (IR) sensor system applications have matured to the stage of undergoing formal qualification test programs. Texas Instruments has designed a complete family of coolers for these tactical applications and has completed qualification programs successfully for two of these designs. Tested were the cryocoolers for the Integral Detector Assembly (IDA) and the Javelin antitank missile system’s Command and Launch Unit (CLU).

Test programs for both coolers included performance validation, ambient temperature extremes, vibration, and mechanical shock. Electromagnetic compatibility/interference and nuclear survivability testing also were included. Life testing was a major component of each test program. This paper presents the test data demonstrating that all requirements have been achieved. Results demonstrating mean time to failure (MTTF) well in excess of the specified 4,000-hour operational life are detailed.
