Experimental study on chemical recuperation process of endothermic hydrocarbon fuel

► Endothermic hydrocarbon fueled scramjet is a chemical recuperation cycle. ► An experiment platform of chemical recuperation of endothermic hydrocarbon fuel is built. ► The recuperation of hydrocarbon fuel consists of chemical and physical recuperation. ► The recuperation effectiveness can be influenced by temperature and residence time. ► The total effectiveness of recuperation of endothermic hydrocarbon fuel can go up by 10%.
