| 摘 要： | 采用涡格法编写了非共面机翼气动力计算程序。以展弦比为８．６的机翼加装帆片为例,进行了气动力计算并作了帆片优化设计。与在南航ＮＨ－２低速风洞中的实验结果比较表明,计算方法和优化设计是成功的。总面积为３．１％基本翼面积的翼尖帆片对减少诱导阻力具有明显效果,诱导阻力因子减小２０％左右。

| Abstract: | non-planar wing aerodynamic computation program was developed using the vor-tex lattices method.The aerodynamic computation and the design of optimized wing sails for aircraft with rectangular wing whose aspect ratio equals 8. 6 were completed.The tests in NH-2 low speed wind tunnel at Nanjing University of Aeronautics and Astronautics showed good a-greement between computation and test values.The wing sails with 3.1 percentage of essential wing area have observable efficiency in reducing induced drag. The factors of the induced drag were reduced by 20 percent. |

| Keywords: | wingtips sails lift augmentation-drag reduction optimizations wind tunnel test |
