The invention provides a hypersonic waverider precursor-inward rotation type air inlet channel integrated design method which comprises the following steps: step 1, designing and obtaining an internal compression reference flow field based on a given air inlet channel inlet design working condition; 2, designing and obtaining an external compression reference flow field based on a given free incoming flow design working condition; step 3, performing viscosity correction on the reference flow fields obtained in the step 1 and the step 2 to obtain a corrected axisymmetric configuration and a non-viscous flow field corresponding to the corrected configuration; 4, designing and obtaining a waverider precursor based on the external compression reference flow field obtained in the step 2 and the non-viscous external compression reference flow field corrected in the step 3; and 5, based on the internal compression reference flow field obtained in the step 1, the non-viscous internal compression reference flow field corrected in the step 3 and the waverider precursor obtained in the step 4, designing to obtain a hypersonic waverider precursor-inward turning type air inlet channel integrated configuration. The aerodynamic performance of the hypersonic waverider front body-inward turning type air inlet channel integrated structure can be effectively improved through the hypersonic waverider front body-inward turning type air inlet channel integrated structure.
