Abstract

In hypersonic aircraft, increase of aerodynamic heat and engine heat leads heat loads in airframe. It could lead structural change of aircraft's component and malfunctioning. Endothermic fuels are liquid hydrocarbon fuels which are able to absorb the heat load by undergoing endothermic reactions. In this study, exo-tetrahydrodicyclopentadiene was selected as a model endothermic fuel and experiments on endothermic properties were investigated with pore structure controlled zeolite catalyst using metal deposition. We secured the catalyst that had better endothermic performance than commercial catalyst. The object of this study is inspect catalyst properties which have effect on heat absorption improvement. Synthetic catalyst could be applied to system that use exo-THDCP as endothermic fuel instead of other commercial catalyst.

극초음속 비행체에서는 공기와의 마찰열과 엔진열의 증가로 기체 내부의 열적 부하가 발생한다. 이는 비행체 내부 구조물의 변형을 일으키고 오작동을 발생시킬 수 있다. 흡열연료는 액체 탄화수소 연료로써 흡열반응을 통해 열을 흡수할 수 있는 연료이다. 본 연구에서는 exo-tetrahydrodicyclopentadiene을 모델연료로써 선정하고 제올라이트 촉매의 금속담지를 통하여 흡열특성의 변화를 측정하는 연구를 수행하였다. 이를 통하여 상용촉매보다 우수한 흡열성능을 가지는 촉매를 확보하였다. 본 연구의 목적은 흡열량 향상에 미치는 촉매의 특성을 연구하는 것이다. 이 촉매는 상용촉매를 대체하여 exo-THDCP를 흡열연료로 사용하는 시스템에 적용될 수 있을 것이다.
