Abstract

The scramjet combustion chamber provides the propulsion for hypersonic vehicle. The fuel is combusted in the chamber to generate thrust. The strut is used to inject fuel into the core of combustion chamber to enhance the mixing and the combustion. The mainstream in a scramjet combustion chamber is at supersonic velocity and high temperature. The tremendous aerodynamic heating will then cause ablation of the strut without adequate cooling. Therefore, effective thermal protection methods must be provided for the strut, especially for the leading edge. Transpiration cooling is one of the most effective cooling methods to protect surfaces at high heat flux conditions, and can effectively protect most part of the strut, but some ablation was found at the strut leading edge.
