Endothermic Heat-Sink of Hydrocarbon Fuels for Scramjet Cooling AIAA 2002-3871

Abstract

Storable liquid hydrocarbon fuels, such as JP-7, JP-8+ 100, and JP-10, that can undergo endothermic reactions may provide sufficient heat sink to enable hypersonic flight without having to resort to cryogenic fuels. The objective of this research is to develop and demonstrate the endothermic potential of these fuels for hypersonic scramjet cooling. A high- pressure bench-scale reactor was used to determine the overall heat sinks (including endotherm), endothermic reforming products, and coking rates for the fuels. A baseline fuel, n-octane, was also investigated for comparison. Tests were conducted in catalyst-coated tubes that simulate a single passage in a practical catalytic heat exchanger/reactor under representative flow conditions.
