액체로켓엔진 극저온 배관 연결부 강도, 기밀해석 및 시험

Strength and leakage analyses of the interface between LOx turbo pump outlet and high pressure LOx pipeline including two flanges, conical seal and connecting bolts were performed. A prototype of the interface was made and strength and leak tests at normal, cryogenic temperatures were conducted. Analysis and test results indicated that the interface is satisfactory to the strength and leakage requirements.
