Facility 245:  2' X 3' Thermal Vacuum Chamber

 

Description: This turbo pumped facility has a horizontal cylindrical chamber with a hinged door. The vacuum chamber is a horizontal stainless steel cylinder 2 feet in diameter by 3 feet deep. The side and rear shroud assembly rests on rails welded to the chamber walls. The door shroud is hinged to the main circular side shroud. The shrouds of this facility are made of black anodized aluminum sheet. 500 Watt metal strip heaters are mounted to the backside of the shroud and controlled by Lambda heater power supplies. The chamber does not provide a method to cool the shrouds.

 

Mode of Operation: After the test article is instrumented with thermocouples and placed in the chamber, ground support equipment cabling is connected through the penetration plate, and ambient functional checks are performed. After roughing down the chamber with the rotary vane mechanical pump, ultimate pressure is achieved with the turbopump. Ports for payload electrical feedthroughs and liquid/gas feedthroughs are located on the west side of the chamber. The vacuum system is comprised of one mechanical pump and a 12” diameter turbopump.
