Abstract

Apparatus for providing a simulated space environment for the testing of articles under low temperature conditions comprising a liquid nitrogen head tank (D), liquid nitrogen subcooler pumps (H), a liquid nitrogen subcooler coil (G), a liquid nitrogen head tank makeup pumps (B), a low pressure liquid nitrogen storage tank (A), a high pressure liquid nitrogen storage tank (C), a liquid nitrogen transfer pump, a vacuum chamber (E) and thermal simulation heat exchanger shrouds (CC, F) contained within the vacuum chamber (E). These components are connected so that the apparatus can be operated both in a subcooled pressurized closed loop system and in a gravity convection system. While liquid nitrogen in this apparatus will produce a stable uniform temperature of -173 DEG C (-297 DEG F) within the shrouds (CC, F) containing the article to be tested, other liquids with similar low temperature characteristics may be used. <IMAGE>
