DFVLR/AEDC Cooperative Thermal Test 2
Abstract
A 10-cm-diam calibration sphere was tested in a space simulation chamber under two different background conditions. In one case, the sphere was enclosed in a black liquid-nitrogen (LN2) cooled shroud, while in the other case the sphere was exposed to the chamber walls which contain some sections not at LN2 temperature. In both cases, the sphere was allowed to reach a stabilized temperature while exposed to one solar constant. The final stabilized temperatures were only 2F (1.1C) different, indicating that the 'hot spots' in the chamber walls are not very significant for this type of test article. It is shown that they can be accounted for by computational techniques.
