초록

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.

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.
