Abstract: To improve the design efficiency and design effect of the aerodynamic shape of the aircraft, the aerodynamic optimization design tool ARI_OPT is developed based on the numerical optimization design technology. ARI_OPT includes modules such as aerodynamic shape parameterization, grid automatic generation, surrogate model optimization, multi-level numerical simulation, and high-efficiency optimization algorithm. The basic principles, methods, and verification results of each module are briefly introduced. The functional verification results of numerical function cases and the application results of the typical single-objective and multi-objective aerodynamic shape optimization problems such as wide-speed range airfoil, multi-element airfoil and flying wing are demonstrated by ARI_OPT. The results strongly prove the effectiveness of the design.
