Thermal Vacuum Test Facility

Metadata Updated: March 8, 2017

FUNCTION: Provides the capability to accurately simulate the space environment for the verification of thermal control system designs and the determination of thermal performance margins and capabilities of space vehicles, experiments, and subsystems.DESCRIPTION: The Thermal Vacuum (TVAC) Test Facility is located within the Payload Processing Facility. It consists of three large chambers and several small chambers, a machinery room, a network of computers, a 26,000-gal liquid nitrogen storage facility, and an assortment of handling and test fixtures. Of the three large chambers, chamber #1 is a 16-ft-diameter by 30-ft-long horizontal end-loading cylinder, and chambers #2 and #3 are 7-ft-diameter by 8-ft-tall vertical bottom-loading cylinders. Chambers #1 and #2 are cryogenic pumped, providing an oil-free vacuum environment. Chamber

3 has a diffusion pump system capable of evacuation rates similar

to the rates that occur during launch ascent. All three chambers are equipped with gaseous nitrogen conditioned thermal shrouds capable of temperatures between -150 [HTML_REMOVED]C and +125 [HTML_REMOVED]C. Numerous bulkheads are available for the pass-through of control, communication, power, and telemetry signals to the test setup.INSTRUMENTATION: The facility has both computerized and manual control of the different chambers[HTML_REMOVED] thermal environments via the chamber shrouds and heaters, cold plates, and quartz lamps. Separate data acquisition systems exist for monitoring and recording measurements from up to 200 thermocouples, 100 resistance temperature detectors (RTDs), quartz crystal microbalances (QCMs), and residual gas analyzers (RGAs).
