75톤급 연소기 연소시험을 위한 지상시험설비 구축 현황

This paper covers construction status of ground test facility for hot-firing test of 75tonf-class combustion chamber. This facility consists of several systems: hydro-pneumatic system, control and measurement system, test stand and gas duct cooling system, etc. Start-up test is currently underway to confirm the function of the essential component in the test facility. After start-up test, performing of normal operation of this facility would be expected to have an effect on schedule and cost reduction of combustion chamber research for KSLV-Ⅱ development.
