摘　　要：变后掠翼技术能使飞机兼顾高速和低速飞行性能,大幅提升飞机的经济效益和作战性能。以寻求最佳变后掠规律为目标,基于CFD数值模拟方法设计并研究了一种翼身组合体模型的空气动力特性,为后期结合Matlab计算工具和标准遗传算法,求得指定高度下的最佳变后掠规律提供了有效的依据。Sweep wing can provide excellent performance on both high and low speed,hence to improve the economic efficiency and operational performance during fight. This paper aims at finding the optimum variable-sweep rule under certain conditions. Therefore,CFD simulation methods were used to study the aerodynamic properties of a variable-sweep wing-body combination model. The data can provide basic research for following work. Matlab is used based on the standard genetic algorithm to analysis the optimal variable-sweep rule under certain height.
