Démonstration en vol d'un cryogénérateur 10 K à adsorption.

Flight demonstration of a 10 K sorption cryocooler.

Résumé

The Brilliant Eyes Ten-Kelvin Sorption Cryocooler Experiment (BETSCE), manifested for flight on STS-77 in May 1996, is the first-ever spaceflight demonstration of sorption cryocooler technology. The sorption cryocooler alternately heats and cools beds containing metal hydride powders to circulate hydrogen as the refrigerant fluid in a closed cycle. On command, it periodically cools a cold head assembly to below 10 K within 90 seconds. The paper describes how BETSCE successfully achieved its primary objectives of: 1) demonstrating the microgravity performance of critical sorption technologies and acquiring the needed flight performance data; 2) identifying and resolving interface and integration issues; and 3) providing hardware qualification and safety verification heritage.
