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。
The variable-swept wing technology enables the aircraft to take into account both high-speed and low-speed flight performance, dramatically improving the aircraft’s economic and operational performance. In order to seek the best law of variable sweep, the aerodynamic characteristics of a wing-body combination model were designed and studied based on the CFD numerical simulation method. For the later combination of Matlab calculation tools and standard genetic algorithms, Good swept forward rule provides an effective basis.
