SUCCESSFUL DISCOVERY SPACE SHUTTLE EXPERIMENTS PERFORMED ON HUGHES HEAT PIPE

 TORRANCE, Calif., Dec. 17 /PRNewswire/ -- Hughes Aircraft Co.'s Electron Dynamics Division (EDD) reported that several successful experiments were accomplished on its heat pipe as part of the Discovery space shuttle mission this month, launched from Kennedy Space Center. "It was the first time an oxygen heat pipe was flown and tested in space," said EDD's project manager, George Fleischman. "The apparatus performed well throughout the tests and added valuable information verifying heat pipe theory in a zero-gravity environment."
 A heat pipe is a closed vessel, containing a fluid that absorbs heat through evaporation and releases that heat through condensation. The Cryogenic Heat Pipe designed by Hughes underwent several tests intended to prove the ability of the devices to start and operate at -351F to -198F. In order to achieve these temperatures, Hughes supplied five stirling cycle cryogenic coolers for the experiment. Fleischman said the start-up and recovery time using super cold liquid oxygen as the working fluid in zero gravity took somewhat longer than similar tests on the ground.
 The heat pipe, cryogenic coolers and related power and control equipment were contained in a canister mounted on the wall of Discovery's payload bay, which permitted the heat absorbed through the pipe to escape to space.
 Discovery Mission 53 also deployed a classified U.S. Defense Department payload as part of its primary manifest.
