Scramjet Fuel Choices: Hydrogen versus Hydrocarbons

Dominic Pace


Currently, scramjet designers have two viable choices for fuel; hydrogen or liquid hydrocarbon. Both of these chemicals have their own advantages and disadvantages as scramjet fuel, and this makes them useful for different scramjet applications. This literature review illustrates the challenges which must be overcome for combustion to occur in hypersonic vehicles, the advantages of each fuel type, recent advances in scramjet combustion technology, and finally, gives an overview of several scramjet designs which have utilised either hydrogen or hydrocarbon fuel.
