The numerical simulations of hydrocarbon fueled scramjet engine have been studied less than them of hydrogen fueled scramjet engine. Ethylene is selected in hydrocarbon because of its good thermochemical properties and a direct-connect scramjet combustor at the American Air Force Research laboratory is taken to a two-dimensional simulation model. Ignition time delay of ethylene was monitored and air throttling was imposed to generate ignition inside the model scramjet.
