Abstract

The laminar burning velocity of endothermic fuel surrogates is measured in this study, in order to investigate combustion characteristics of aviation fuel after being used as coolant in an active cooling system of a hypersonic flight vehicle. A Bunsen burner was manufactured such that the laminar burning velocity can be taken for two types of surrogate fuels, SF-1 and 2. The results showed that the burning velocity of surrogate fuels was faster at high equivalence ratio conditions than that of the reference fuel (RF), and specifically, the velocity of SF-1 had the maximum value at the highest equivalence ratio compared with those of SF-2 and RF.

본 연구에서는 항공유가 극초음속 비행체용 능동냉각시스템의 냉원으로 사용되면서 흡열분해된 후의 연소특성을 확인하는 연구의 일환으로, 흡열분해 모사연료에 대한 층류화염 전파속도를 측정하였다. 흡열분해 모사연료 2종(SF-1, 2)을 제조하고 분젠버너 시험장치를 제작하여 층류화염속도를 측정한 결과 기준연료(RF)와 비교해 보면 전체적으로 높은 당량비에서 화염전파속도가 빠르게 나타나고 있으며, 특히 SF-1이 SF-2 및 RF보다 훨씬 높은 당량비에서 최대 속도를 가짐을 확인하였다.
