| In order to meet the design requirements of wide Mach number flight from land take-off to high-speed cruise of aerial
vehicle，combined with the advantages of increasing lift/drag ratio of waverider body and simple and realizable adjustment of two -
dimensional inlet channel profile，a two-dimensional TBCC inlet was designed based on waverider forebody. The numerical simulation and
analysis of the two-dimensional inlet under different working conditions were carried out. The total deflection angle of the inlet was 23°and
the lip angle was 10°，which could effectively restrain the spillage drag. The numerical simulation results show that the TBCC inlet can start
successfully when the flight Mach number is 2.0~4.0. When the flow coefficient is above 0.60，the total pressure recovery coefficient of the
inlet is 0.47~0.85，and the aerodynamic performance is good. At the same time，the numerical simulation analysis of the two-dimensional
TBCC inlet in the transition mode was carried out，and the influence of different flow distribution schemes on the inlet performance was
explored. It is found that with the increase of the flow ratio，the aerodynamic performance of the stamping channel outlet increases，and the
flow coefficient and the total pressure recovery coefficient increase. |
