| Abstract: | A simple and fast model is presented,which allows the calculation of 2D mixture-compress supersonic inlets performances,such as pressure recovery,mass flow ratios,additive-drag coefficient,wave-drag coefficient and effective kinetic efficiency,with an acceptable accuracy.Inlets geometrical parameters,such as height,ratio of height and width,angles of vertical compressing ramp,are investigated by considering its performances.Simulated Annealing (SA) algorithms is presented for calculating the models of the optimization design. |
