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.
