摘要:: 升力前体由于前缘激波不能附着于前体前缘，其上下表面流场存在相互耦合，进而导致其下表面流场存在较强的横向流动，这会对腹部进气系统的设计造成不利影响。为了使前体出口流场能较好地保持二维流动特征，通过在升力前体两侧增加小角度抑流斜楔，以抑制横向流动。这种升力前体及一体化进气系统的数值模拟表明，该升力前体出口流场二维特征良好，采用该前体的进气系统能较好地维持理想的流场结构，并具有较优的性能。

Abstract:: Because shock wave can not attach to the leading edge of a lift forebody, the upper and lower flowfields are coupled, which induces a strong transverse flow of lower surface flow field. It may cause a negative influence on the belly-sided air inlet system. In order to make the forebody outlet flow field remain 2-D flow feature, small angle restraining wedges are put on both sides of lift forebody so as to restrain the transverse flow. Numerical simulation of the lift forebody and integrational inlet system shows that the 2-D feature of the lift forebody outlet flow field is perfect. The air intake system with this kind of forebody can keep the ideal flow-field structure quite well.
