N2 - For the integrated design of internal and external flow of aircraft, the intake and exhaust boundary conditions of discrete adjoint equation under the power state of propulsion system are studied. The chain derivation rule is used to avoid direct variations of conservative variables. The difficulty of variations of intake and exhaust boundary conditions is greatly simplified by introducing intermediate variables, then the efficient sensitivity analysis method for design variables of exhaust effect is presented. The accuracy of numerical simulation of intake and exhaust is verified by TPS standard model calculation, and the accuracy of adjoint-based sensitivity calculation is verified by comparing with finite difference method. Taking the numerical simulation of intake and exhaust effects of BWB (Blend Wing Body) configuration as an example, the integrated optimization design with or without power conditions was carried out, and the flow field characteristics such as design history, load distribution and pressure distribution under the two conditions were compared and analyzed.
