초록

극초음속 비행체는 속도가 증가할수록 공기와의 마찰열과 엔진열이 증가한다. 이러한 열적부하는 비행체 구조물의 변형을 야기하고 오작동을 유발할 수 있다. 흡열연료는 액체 탄화수소 연료로써 열분해 반응, 촉매분해 반응과 같은 흡열반응을 통해 열을 흡수할 수 있는 연료이다. 본 연구에서는 methylcyclohexane을 모델연료로써 선정하여 흡열특성을 측정하는 연구를 수행하였다. 반응열을 향상시키기 위해 제올라이트를 적용하였고 HZSM-5가 흡열량 향상에 가장 효과적인 것을 확인하였다. 본 연구의 목적은 흡열량 향상에 미치는 촉매의 영향을 연구하는 것이다. 이 촉매는 케로신연료를 흡열연료로써 사용하는 시스템에 적용될 수 있을 것이다.

For hypersonic aircraft, increase of flight speeds causes heat loads that are from aerodynamic heat and engine heat. The heat loads could lead structural change of aircraft's component and malfunctioning. Endothermic fuels are liquid hydrocarbon fuels which are able to absorb the heat loads by undergoing endothermic reactions, such as thermal and catalytic cracking. In this study, methylcyclohexane was selected as a model endothermic fuel and experiments on endothermic properties were implemented. To improve heat of endothermic reaction, we applied zeolites and confirmed that HZSM-5 was the best catalyst for the catalytic performance. The objective is to investigate catalytic effects for heat sink improvement. The catalyst could be applied to system that use kerosene fuel as endothermic fuel.
