Abstract

This study aimed to obtain data for a comparative analysis of the properties of bio aviation fuel to be developed in the future by measuring and comparing the ignition delay times of various presently used aviation fuels. In the case of petroleum-based aviation fuel, the ignition delay time of exo-THDCP was 4.92 ms, which was 3.42 times longer than 1.44 ms of Jet A-1 at $590^{\circ}C$ / 55 bar. In the case of foreign bio aviation fuel, the ignition delay time of 11POSF7629 was the longest (1.16 ms), while the ignition delay time of 10POSF6308 (1.06 ms), 12POSF7720 (1.07 ms), and 07POSF5172 (1.05 ms) were similar.

본 연구에서는 향후 개발될 바이오 항공유의 특성을 비교 분석하기 위한 기초 자료를 확보하기 위해, 여러 가지 항공유의 점화지연시간을 측정하여 결과를 비교하였다. 석유계 항공유의 경우에는 $590^{\circ}C$, 55 bar 조건애서 exo-THDCP의 점화지연시간이 4.92 ms로 측정되어 Jet A-1의 측정값인 1.44 ms 보다 3.42배 긴 것을 확인하였다. 또한 외국 바이오 항공유의 경우에는 Sasol사의 11POSF7629가 1.16 ms로 점화지연시간이 가장 길게 측정되었고, UOP사의 10POSF6308은 1.06 ms, 12POSF7720는 1.07 ms, 그리고 Sasol사의 07POSF5172는 1.05 ms로 모두 비슷하게 측정되었다.
