| 摘 要： | 针对某民机翼身组合体进行了翼身整流设计,以减弱机翼机身附面层之间的相互干扰,消除翼身结合处气流的分离,改善该民机的阻力性能。将翼身整流的多种设计方案(不同类型,不同安装位置,不同的几何尺寸等)配置到某民机翼身组合体模型上,用CFD方法对其流场进行粘性绕流数值模拟并对结果进行优化分析,得到了针对该民机减阻效果较好的翼身整流设计方案。

| Abstract: | To weaken the interference between civil aircraft wings and fuselages boundary layer and eliminate the resulting flow separation at the wing-body junction,reducing the interference drag of civil aircrafts,fairings should be installed to wing-body junctions. Fairings of different kinds and sizes are installed to the wing- body junction of the civil aircraft. Then we use CFD tools to calculate the flow fields of the civil aircraft with different fairings. Finally,fairing with the best drag reduction effect is... |
