고고도 환경 추력기 지상 시험 설비 현황

Foreign ground test facilities for high altitude thruster is briefly described. Environmental conditions of high altitude thruster is different from sea level conditions. In order to demonstrate those conditions like vacuum condition, high altitude test facilities are necessary. Typical high altitude test facilities that is being operated today are P1.0, P4, P6 test facilities in German aerospace center and vacuum test facilities operated in United States. In this paper, it is described that fuels which each facility uses, vacuum chamber property and some characteristics of the facilities are researched.
