10 November 1987 Experience With Supercritical Helium Cooling On A Rocket Sensor
Author Affiliations +
A large telescoped infrared sensor was successfully flown on a rocket. A supercritical helium cryogenic system was used to cool the various parts of the sensor and to avoid cooling problems associated with liquid/gas phase mixing during the weightless part of the flight. The design and operational experience are presented. Since the flight of the sen-sor lasted only eight minutes, most of the operational time was spent calibrating and testing the sensor on the ground. This testing was relatively expensive since approxi-mately 20,000 liters of liquid helium were consumed. Alternate approaches to the design and operations are discussed which can improve the economy of the calibration and testing operations.
