Application of Vacuum Technology in Aerospace Industry

The main link closely related to vacuum science and aerospace technology comes from the simulation of space environment, because various spacecraft such as launch vehicles, artificial satellites, manned spacecraft, space stations, space probes, and space shuttles are all carried out in the natural vacuum of the universe during space flight.

Therefore, in addition to being directly affected by the vacuum environment in space, they are also affected by solar radiation, various charged particles, and temperature. These factors will cause changes or damage to material properties; The malfunction of instrument sensitivity can disrupt the operation of these aircraft and even cause injury or death to astronauts.

Therefore, it is necessary to establish a space simulation experimental device on the ground to simulate the space environment. Because simulation experiments on the ground are only conducted before various aircraft are launched. Mastering the conditions and characteristics of spacecraft operation in space, eliminating various hidden dangers during flight, is necessary to ensure the safety of spacecraft and astronauts. In order to meet these requirements, there are currently many simulation devices established on the ground.
