In response to the problem of embedded payload separation by using integrative computation of internal and external flows in the front end of the intake duct due to engineering constraints, a computational aerodynamics coupled six degree of freedom motion model, dynamic nested mesh, and internal and external flow coupling calculation strategy were used to conduct numerical simulation research on the unsteady flow field of payload separation by using integrative computation of internal and external flows. The characteristics of payload separation motion under the condition of integrated internal and external flow coupling and its impact on the flow field of the internal flow intake duct were analyzed and evaluated. The results showed that, considering the safety of payload separation and its impact on the intake flow field, the dispersed deployment scheme was relatively stable; the two-point symmetrical placement scheme resulted in the intake duct
