Abstract

Fuel injection system into scramjet engines are a field that is still developing today. The fuel used in scramjet is generally either liquid or a gas. In a scramjet engine the fuel and air should mixed to approximately stoichiometric proportions for effective combustion. The major problem of scramjet fuel injection is that the air flow is quite fast. Meaning that there is minimum time for the fuel to mix with the air and ignite to produce thrust. The main fuel that is used for combustion is hydrogen. Hydrocarbans present more of a difficult compared to hydrogen due to longer ignition delay and the requirement for more advanced mixing techniques.
