The invention discloses a double-design-point three-dimensional internal contraction air inlet channel inverse design method based on the osculating theory, and relates to the field of wide-speed-range air inlet channels applied to hypersonic aircrafts. An osculating theory and a double-design-point inverse design method are combined, a basic flow field is constructed in different osculating planes by adopting the double-design-point inverse design method, and then the wide-speed-domain double-design-point three-dimensional internal contraction air inlet channel inverse design method is formed. The inlet shape curve is designed to be a curve with any continuous curvature, and the design freedom degree of the inlet shape curve is enlarged; an inlet shape curve is dispersed into a plurality of points by applying an osculating theory, osculating planes are constructed, a basic flow field is designed in the plurality of osculating planes based on a double-design-point inverse design method, and wide-speed-domain double-design-point three-dimensional internal contraction air inlet duct inverse design is simultaneously carried out in different osculating planes according to high/low Mach number flow requirements; and by actuating the variable configuration surface, the starting of the air inlet channel under a low Mach number is realized, and the expected flow capturing capability is realized.

    基于吻切理论的双设计点三维内收缩进气道反设计方法,涉及应用于高超声速飞行器的宽速域进气道领域。将吻切理论与双设计点反设计方法相结合,在不同吻切平面内采用双设计点反设计方法构造基本流场,进而形成宽速域双设计点三维内收缩进气道反设计方法。将入口形状曲线设计为任意曲率连续的曲线,扩大入口形状曲线的设计自由度;应用吻切理论将入口形状曲线离散成若干个点,构建吻切平面,在若干个吻切平面中基于双设计点反设计方法设计基本流场,实现在不同吻切面内同时根据高/低马赫数流量需要开展宽速域双设计点三维内收缩进气道反设计;通过作动变构型面,实现进气道在低马赫数下的起动并且具有预期的流量捕获能力。
