World's largest vacuum chamber

vacuumchamber

Die NASA baut grade ein paar Gerätschaften zum Testen ihrer neuen Raumschiffe (hach) Orion, die Teil eines Programmes ist, um Astronauten dauerhaft auf dem Mond zu stationieren (hach). Darunter ist eine Akkustik- und eine Vibrationskammer, in der die Auswirkungen des Schalls und der Vibrationen wärend des Starts auf das Material getestet werden. Außerdem bauen sie die größte Vakuum-Pumpe der Welt.

Thermal vacuum testing and electromagnetic interference testing will take place in the vacuum chamber. Thermal vacuum testing will confirm that the spacecraft can withstand the extreme hot and cold temperatures present in space, and electromagnetic interference testing will verify the reliability of Orion's communication and electronic systems.

The 75,000-pound craft will sit on a huge vibration table; comprising a 125,000-pound mass that must be shaken with an intensity equal to that of a launch.

Twenty-four horns will blow high-pressured nitrogen gas to match the intensity level of the sounds produced during the launch. Most acoustic facilities have around two or three horns. But for this facility, everything is being built bigger in scale to more accurately assess the spacecraft.
