| 摘 要： | 采用数值模拟方法进行了FB-4000-1000与FB-4000-2000钝后缘翼型的后缘减阻装置研究.分析了后缘减阻隔板安装位置对翼型气动特性的影响.其中后缘台阶中部安装隔板,以升力的小幅损失为代价实现中小迎角范围内减阻约35％,而在较大迎角时减阻约20％.

| Abstract: | Computational simulations were introduced to analyze FB-4000-1000,FB-4000-2000 blunt trailing edge airfoils and the drag reduction method with trailing edge splitters.Three kinds of splitters were study.The one which the splitter was installed in the middle of trailing edge step,made about 35% drag reduction with a bit of lift decrease at small and middling attack angle;while at high attack angle it provided about 20% reduction of the drag. |
