Research on Multi-Objective Optimisation System of Aircraft Aerodynamic Layout Based on Genetic Algorithm

In this paper, a multi-objective optimization system for aircraft aerodynamic layout based on genetic algorithm is designed and implemented, which proposes the integration of parametric modeling and CFD computation, gradient-assisted evolution strategy and multi-level agent model evaluation mechanism, and constructs a complete optimization process. The test validation shows that the system significantly improves the optimisation efficiency and aerodynamic performance, successfully generates the optimal design scheme under multi-objective trade-off, and provides an efficient and practical solution for the optimisation of aircraft aerodynamic layout.
