한국형발사체 75톤 연소기 기술검증시제(TDM#1) 연소 시험 결과

This paper is described for the test results of repaired combustion chamber TDM#1 after hot firing test which was occurred to the high frequency combustion instability. This test was performed in KARI"s Naro Space Center. The results are as follows. CCTF is possible for the stable supply with estimated propellant flow rates into combustion chamber. The low pressure hot firing test is improper to know the combustion instability of combustion chamber.
