Korea Aerospace Research Institute invests 400 million won over three years to develop test equipment for electric propulsion devices essential for deep space exploration

The Korea Aerospace Research Institute has developed a test device necessary for the development of electric propulsion devices that can be used in artificial satellites and deep space exploration vessels. Electric propulsion systems are different from chemical propulsion systems that use combustion reactions.
It is a device that generates plasma using electrical energy to obtain propulsion. In order to develop electric propulsion devices that need to operate in space for tens of thousands of hours or more, it is essential to verify performance and longevity. For verification
To achieve this, it is necessary to create a vacuum environment of 1/100 millionth of an atmosphere or less for plasma generation through electrical discharge, a temperature control function that can quickly change between low and high temperatures, and special test equipment that can perform plasma diagnosis.
. The test facility for the electric propulsion device developed by the hospital has a diameter of 3.8 meters and a length of 10 meters. The Korean company invested approximately 4.2 billion won (approximately 468.1 million yen) over a three-year development period.
Produced with industry. Using this device, it will be possible to test 200 millinewton electric thrust devices. The hospital is gradually installing additional disks that can handle cryogenic temperatures, increasing the thrust by 1 newtonk.
The plan is to improve the system so that it can be tested using an electric propulsion system. In the future, electric propulsion test equipment will be used for satellite development and deep space exploration, and Korean companies and research institutes will
We will open it up to
