Abstract

Ball Aerospace Systems Division is developing, through a series of contracts, a J-T cryocooler for space applications. The acronym for the current program is COOLLAR and stands for Cryogenic On-Orbit Long Life Active Refrigerator. The primary objective of COOLLAR is to develop and demonstrate a flight capable cryocooler (referred to as the Engineering Development Model (EDM)) that is based on the Joule-Thomson (J-T) cycle. The previous contract, the Advanced Breadboard (ABB), was completed in March, 1992. The ABB program successfully demonstrated the solution to many of the major issues of the J-T cryocooler technology at the breadboard level. This paper will present an overview of the J-T cryocooler technology, the COOLLAR program, the EDM design and supporting test results.
