The inlet is designed for Mach 2.5 by applying the Method of Characteristics. Realistic ramp bleed and throat bypass systems are simulated by a two-dimensional, finite volume, multi-block TVD Navier-Stokes code. From the calculations, the role of ramp bleed and throat bypass systems are revealed. And the mechanism of improving the pressure recovery ahead of an inlet "unstart" is found for the first time in detail. The results also show that the throat gap, or slot, constructs an optimum equivalent wall configuration automatically by the flow conditions around the systems. This noteworthy result can be obtained because of the great advantage of the CFD approach., 資料番号: NALSP0014019, レポート番号: NAL SP-14}, title = {設計における数値解析の活用について(その8): 超音速機用混合圧縮インテーク}, year = {1990} }
