초록:30톤급액체산소/케로신액체로켓엔진개발의중간단계로터보펌프-가스발생기개회로연계시험이수행되었다.터보펌프-가스발생기개회로연계시험은엔진시스템작동모사환경시험으로서가스발생기로의추진제는터보펌프출구를통해공급되지만, 가스발생기출구가스는터빈구동에이용되지않고외부로배출된다. 터보펌프-가스발생기개회로연계시험목적, 시험설비구성, 제어시스템의작동조건, 시험수행절차, 연계시험기의구성형태,개회로연계시험결과가제시되었다.터보펌프-가스발생기개회로연계시험결과,연계시험기의예냉절차와시동특성,정격작동성및안정적인종료특성이액체로켓엔진시스템작동환경모사조건에서확인되었다.Abstract: Turbopump-gas generator open-loop coupled tests are performed during the development of a30tonf-LOx/Kerosenerocketengine.Intheturbopump-gasgeneratoropen-looptests,thepropellantstogasgeneratoraresupplied from the outlets of turbopump, while the gas exhausted from the gas generator is vented out to theatmosphere, instead of being used to turbine driving. This paper presents the objectives, procedure, and results of theopen-loopcoupledtest, inadditiontoaschematicrepresentationofthetestapparatusandtheoperatingconditionsforthe test facility system and control system. The results of turbopump-gas generator open-loop coupled test confirmchill-down procedure, startup characteristics, nominal operability and smooth shutdown of the open-loop coupled TestPlantintestconditionssimulatingenginesystemoperationenvironment. |
