Abstract

In this study, the ignition delay time of blended aviation fuels was measured and analyzed to confirm the characteristic of ignition delay according to the blending ratio of bio-aviation fuel to petroleum-based aviation fuel. The ignition delay time of bio-aviation fuel(Bio-6308) was shorter than that of petroleum-based aviation fuel(Jet A-1) at all measured temperatures; further, the ignition delay time of the blended aviation fuels shortened as the ratio of Bio-6308 increased. It was confirmed that the aromatic compounds constituting the Jet A-1 affect these results; this was done by comparing the obtained ignition delay time with that of n-heptane/Toluene.

본 연구에서는 석유계항공유와 혼합하여 사용이 가능한 바이오항공유의 혼합 비율에 따른 점화지연 특성의 변화를 확인하기 위하여, 두 항공유를 일정한 비율로 혼합한 시료의 점화지연시간을 측정하여 분석하였다. 측정한 모든 온도 조건에서 Bio-6308의 점화지연시간이 Jet A-1의 점화지연시간보다 짧게 나타났으며, 두 항공유를 일정한 비율로 혼합한 경우에도 Bio-6308의 함량이 증가할수록 점화지연시간은 짧아지는 경향을 보였는데, 이는 Jet A-1을 구성하는 방향족 화합물의 영향 때문임을 n-heptane/Toluene의 점화지연시간 측정을 통해 확인하였다.
