Multidisciplinary Multi-Point Optimization Design of Transport Aircraft Wing

In traditional aircraft design, the interaction between aerodynamic and structural discipline is not fully considered in the preliminary design stage, so it is difficult to obtain the optimal design. In this context, this paper takes the transport aircraft wing as the research object to develop an aerodynamic/structural multidisciplinary multi-point optimization design method for transport aircraft wing in the preliminary design stage. In this study, the optimization method of Kriging surrogate model is used to carry out multi-point optimization design of transport aircraft wing under various typical speed. During optimization design, using the full-velocity potential equation for aerodynamic calculation, and Ansys for structural finite element analysis to optimize the design with the lift-to-drag ratio and structural weight as the goals. The effectiveness of the method was preliminarily verified.
