Краткое описание

The problem of computing the aerodynamic performance of high-speed flying vehicles (FVs) with airbreathing jet engines is considered. An efficient, stable, rapid, robust, and informative computational instrument is required in investigations aimed at improving airframe design. A numerical method based on the hypersonic small-disturbance theory and the Godunov-Kolgan method is used in this study as the basic instrument in calculating the flow fields and total aerodynamic performance of a FV. In order to calculate the air inlet performance (mass flow rate coefficients, momentum components, etc.), the numerical results for the flow parameters at the entrance of the air inlet are used. The contribution of the engine air inlets to the total aerodynamic performance of the FV is determined by the momentum theorem. The results are compared with the experimental data and computational results using a Reynolds-averaged Navier-Stokes code. The performance of an axisymmetrical body with two air inlets is calculated.
