The application of xenon in ion motors and plasma screws in aerospace and satellite industries uses fuel xenon, which is about 4.5 times heavier than air due to its high weight and density. It is mainly used to maintain the orbital position and maneuver control of satellites. At the end of the magnetic cavity of the ion motor are two metal nets with positive and negative charges. The powerful electromagnetic thrust generated by positive charges and ammonia ions ejects cylindrical ions at a high speed (about 100 oookm µ h), generating a recoil force to propel the aircraft forward. Its thrust is much smaller than that of a chemical fuel engine. At full speed, every 2500W of electric energy consumed by the ion motor can only produce L'llokgf thrust. However, it can run for months or even years. This allows the final speed of the aircraft to reach 10 times the speed of the chemical fuel engine. The non condensing characteristic of xenon makes it possible to start or stop the ion rocket engine almost immediately, thus simplifying the design of power distribution system and insulator.
As a foaming agent, xenon has the following advantages: no pollution, no chemical reaction with the surface materials of spacecraft. It is non-toxic and will not pollute the earth's space environment and biosphere. Ensure the health of soil testing personnel and clean the environment inside and outside the laboratory. The application scope of xenon ion rocket engine has expanded from the early north-south positioning of geostationary satellites to position control, orbital maneuver and non propulsion applications, such as plasma switch and interplanetary navigation. Generally, xenon particulate engine is used; The xenon particle engine of the satellite consists of four gas tanks (2:2 standby) and two power processors to complete the maintenance of the satellite orbital position. Each xenon particle engine only consumes 2.5kg fuel per year, so only 5kg fuel is needed to maintain satellite orbit each year. Xenon particles can produce greater thrust, because of its inertia, it is not easy to corrosion, but also safe. In the mid-1990s, this technology began to be used in various satellites. Generally speaking, the satellite uses 6000L xenon.
