A thermal vacuum test chamber, with its door open, at NASA's Johnson Space Center. A thermal vacuum chamber ( TVAC ) is a vacuum chamber in which the radiative thermal environment is controlled. Typically the thermal environment is achieved by passing liquids or fluids through thermal shrouds for cold temperatures or through the application of ...
Chamber B is smaller, with a diameter of 20 feet (6.1 m), and is served by two 100,000 pound cranes. Like Chamber A, it has two airlocks; one of them is configured to a water deluge system and other elements needed to simulate oxygen-rich environments encountered on spacecraft.
The aluminum test chamber is a vacuum-tight aluminum plate vessel that is 100 feet (30 m) in diameter and 122 feet (37 m) high. Designed for an external pressure of 2.5 psi (17 kPa) and internal pressure of 5 psi (34 kPa), the chamber is constructed of Type 5083 aluminum which is a clad on the interior surface with a 1 ⁄ 8 in (3.2 mm) thick type 3003 aluminum for corrosion resistance.
Sunshield full-size test for the James Webb Space Telescope. In spacecraft design, a Sun shield restricts or reduces heat caused by sunlight hitting a spacecraft. [6] An example of use of a thermal shield is on the Infrared Space Observatory. [6] The ISO sunshield helped protect the cryostat from sunlight, and it was also covered with solar ...
Materials for use in vacuum are materials that show very low rates of outgassing in vacuum and, where applicable, are tolerant to bake-out temperatures. The requirements grow increasingly stringent with the desired degree of vacuum to be achieved in the vacuum chamber. The materials can produce gas by several mechanisms.
The facility consists of a 7-foot-diameter by 21-foot-long chamber containing a full gaseous helium thermal shroud. The chamber is surrounded by a Class 100 Clean Room with an adjoining Class 1000 build-up area. The 7V chamber can be conditioned from atmospheric pressure to 10 −7 torr. [1]
