한국형발사체 추진제 탱크 가압제어용 극저온 솔레노이드밸브 개발 시험

The cryogenic solenoid valve has been developed for propellant tank pressurization system of the KSLV-II. In the KSLV-II, cryogenic solenoid valve is employed to control the flow of gaseous helium which is stored at propellant tank as cryogenic and hight pressure state. The DM(development model) of solenoid valve was manufactured and its performance tests have been carried out. This paper summarized the performance test results of cryogenic solenoid valve for propellant tank pressurization system of KSLV-II.
