Application of vacuum technology in aerospace industry

    The main link closely related to vacuum science and aerospace technology is the environment simulation of space, because various space vehicles such as launch vehicles, artificial satellites, manned spacecraft, space stations, space probes, and space shuttles are in the process of space flight. It takes place in the natural vacuum of the universe.

  Therefore, in addition to being directly affected by the vacuum environment of space, they are also affected by solar radiation, various charged particles and temperature. These factors will cause changes in material properties or damage; instrument sensitivity failures, which will disrupt the work of these vehicles and even cause astronaut casualties.

    For this reason, it is very necessary to establish a cosmic space simulation experiment device that simulates the space environment on the ground. Because only the simulation experiments on the ground are passed before various aircrafts go to the sky. Only by mastering the conditions and characteristics of spacecraft working in space and eliminating various hidden dangers in flight can the safety of the spacecraft and astronauts be ensured. In order to meet these requirements, there are many kinds of simulation devices established on the ground at present.
