Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Agencia Espacial NASA, sobre como sería un viaje al espacio en una cámara de vacío.
NASA, nos dice: " Cuando usted necesita para probar el hardware diseñado para operar en las vastas extensiones de espacio, se inicia en una cámara de vacío.NASA’s Glenn
Research Center en Cleveland tiene muchas de ellas, peroCámara al vacío 5 (VF-5) es especial. Apoyo a la prueba de los sistemas de propulsión y de energía eléctrica, VF-5 tiene la velocidad de bombeo más alta de cualquier instalación de pruebas de propulsión eléctrica en el mundo, lo cual es importante en el mantenimiento de un entorno de espacio como continuo......."

When you need to test hardware designed to operate in the
vast reaches of space, you start in a vacuum chamber. NASA’s Glenn
Research Center in Cleveland has many of them, but Vacuum Chamber 5
(VF-5) is special. Supporting the testing of electric propulsion and
power systems, VF-5 has the highest pumping speed of any electric
propulsion test facility in the world, which is important in maintaining
a continuous space-like environment.
The cryogenic panels at the top and back of the chamber house a
helium-cooled panel that reaches near absolute zero temperatures (about
-440 degrees Fahrenheit). The extreme cold of this panel freezes any air
left in the chamber and quickly freezes the thruster exhaust, allowing
the chamber to maintain a high vacuum environment. The outer chevrons
are cooled with liquid nitrogen to shield the cryogenic panels from the
room temperature surfaces of the tank.
Most electric propulsion devices, such as Hall Thrusters, use xenon
as a propellant, which is very expensive. By capturing the used xenon as
ice during testing, researchers are able to recover the propellant to
reuse, saving NASA and test customers considerable costs.
The oil diffusion pumps along the bottom of the tank capped by
circular covers use a low vapor pressure silicon oil to concentrate
small amounts of gas to the point where it can be mechanically pumped
from the chamber.
VF-5 will continue to provide a testing environment for Glenn’s
advanced Solar Electric Propulsion technology needed for future
astronaut expeditions into deep space, including to Mars.
