  • According to the aerodynamic and stealthy performance requirements in non-circular cross section configuration design, and based on the concept of multi-objective optimization, the Pareto method and genetic algorithm were combined and tournament selective reproductive operator, Niche and Pareto filters technology were used to get the results with favorable distribution. Further more, response surface methodology was proposed to improve optimization efficiency.The aerodynamic performance of the missile was calculated by N-S equation numerical method, and radar cross section was calculated by physical optics and physical theory of diffraction. Compromise and optimization between these two objective functions, aerodynamic and stealthy performance of non-circular cross sections based on Pareto genetic algorithm, were realized, and the results are satisfactory.
