An Experimental Assesment of Combustion Stability of Coaxial Swirl Injector and Impinging Injector through Simulating Combustion Test
상압기상연소시험을 통한 동축형 스월 분사기와 충돌형 분사기의 연소안정성 평가
Abstract
This study was aimed to assess combustion stability for coaxial swirl injector and FOOF impinging injector which would be candidates in liquid rocket engine combustors. Simulating combustion tests under atmospheric condition have been conducted by gaseous oxygen and the mixture of methane and propane, using two actual injectors. By analyzing the measured dynamic pressure signals, we have evaluated the combustion stability margin of both injectors by drawing a stability map.
