Strong interference region profile design method based on two-dimensional bending characteristic line theory

The invention develops a strong interference area profile design method based on a two-dimensional bending characteristic line theory. The method comprises the following steps: step (1), obtaining a preset shock wave shape; (2) acquiring flow field data i; (3) determining a wall surface shape i according to a preset shock wave shape and the flow field data i; (4) executing flow field simulation according to the wall surface shape i to obtain flow field data i + 1; (5) according to the flow field data i + 1 and the flow field parameters corresponding to the wall surface shape i, judging whether the similarity between the simulation shock wave shape i and the preset shock wave shape meets the requirement or not; and (6) if the requirement is met, outputting the shape i of the wall surface, if the requirement is not met, i = i + 1, and executing the steps (2)-(6) again. Therefore, the technical blank in the field of aircraft appearance reverse design in the strong shock wave interference area in China is filled
