A test article representing an upper stage avionics thermal control system was developed and tested under simulated space environments of full-sun and no-sun. The upper stage avionics packages are located in space-viewing windows. Heat is carried from package mounting plates to cylindrical secondary radiator skins by heat pipes. Test results were correlated and simulated with an analytical model for the test article. The selected window module approach was found to the versatile, to allow repeated package removal with no performance penalty, and to operate satisfactory with a simulated one-heat-pipe-out failure.
