description The invention discloses a double-design-point wide-speed-range inner contraction air inlet channel design method based on bending shock waves, and relates to the field of aircraft wide-speed-range air inlet channels. The method comprises the following steps: 1) determining a high/low Mach number design point of the hypersonic-speed internal contraction air inlet according to the design requirement of a hypersonic-speed aircraft; 2) constructing a double-design-point axisymmetric basic flow field; (3) the fan-shaped inlet is placed in a high-Mach-number basic flow field to be subjected to streamline tracking, and an air inlet channel basic compression molded surface is obtained; and 4) designing a high/low Mach number working condition actuation profile and an actuation scheme. And the design of the hypersonic-speed wide-speed-domain contraction air inlet channel can be simultaneously carried out according to high/low Mach number flow requirements. According to the hypersonic-speed wide-speed-domain contractio
