The ADJOPT, an aerodynamic layout optimization design software based on the attendant operator, is developed. The software is applied to the layout of large aircraft optimized by the traditional design method. The multi-parameter and high-precision optimization design of the wing is carried out. The influence of the nacelle and the airframe on the aerodynamic characteristics of the wing achieved significant optimization results. The results show that the multi-parameter optimization design can fully tap the design potential of a good layout and further improve the layout performance.
