Multiobjective optimization design of aerodynamic configuration constrained by stealth performance

According to the configuration, aerodynamic and stealth performance requirement in aircraft configuration design, the optimization design model and analysis method of aircraft aerodynamic-stealth integration optimization design are built by combining the Pareto method and genetic algorithm based on the concept of multiobjective optimization. To get the results with favorable distribution, the population sorting, niche faring, filters methods are used. For the design requirement, the parameterization of complicated aircraft geometry and design variables selecting principles are presented. To meet the design requirement, the aircraft configuration integral optimization is carried out considering the subsonic and supersonic aerodynamic performance as design objects constrained by stealth performance, and the optimization result is satisfying.
