Considering the requirements of future horizontal taking off and horizontal landing vehicle, a double-sided vehicle configuration with scramjets installed in each side was constructed. The on-design Mach number for this scramjet is 7 and it works in the range between Mach 7 and 10, with a stream-traced inward inlet and circular combustor. 3D numerical simulations of the scramjet were conducted. Performances of inlet and whole scramjet, and the field contours of fuel mixing and combustion are provided. Besides, a 1D performance analysis method was used to predict combustor performances. The results show that the scramjet can generate positive thrust and it could reach the goal of propelling a vehicle to cruise or accelerate by thorough integration design of airframe and propulsion. Besides, it is also shown that the pressure distribution calculated by 1D and the 3D methods are located in 15% error band, which means that the 1D analysis method can be used to predict the performance of this scramjet.
