| Abstract: | Hypersonic vehicle has become one of main goals about development of aerospace in the major world powers.Analysis research of X-43A and X-51 is conducted.Aerodynamics research of two hypersonic configurations integrated with scramjet is present based on three-dimensional simulation.Investigation shows that fuel impingement angle is of an important influence on moments（including the pitching moment and roll moment） and aerodynamic force.In the same fuel inlet condition,hypersonic vehicle can get the maximum lift and minimum pitching moment in the condition that the fuel impingement angle is-20°.In the same volumetric capacity condition,X-43A has dominant species in aerodynamic stability compared with X-51.The pitching moment and roll moment of X-51 are higher by 15%～28% and 10%～24%,respectively. |
