为改善高速飞机之起飞着陆性能,除采用一般机械式衿翼外,气动增升是大有发展前途的措施,其中吹气衿翼在增升以缩短滑跑距离方向的得益也还是明显的。但吹气衿翼的效率与机翼平面形状及管路通道等具体安排有密切联系,牵涉面甚广。虽然国内外多年来对于弦向吹气衿翼积累了比较多的实验数据,但在理论探讨上却并没能获得完整的计算吹气量与各种气动系数增量之间关系的解析方法。考究其原因,对吹气衿翼而言,最大升力系数的增加 In order to improve the take-off and landing performance of high-speed aircraft, the aerodynamic increase is a promising measure in addition to the general mechanical wing, and the benefit of the blowing wing in increasing the shortening of the runway distance is also obvious . However, the efficiency of the inflatable wing is closely related to the specific arrangements such as the plane shape of the wing and the passage of the pipeline, and so on. Although many experimental data have been accumulated at home and abroad for chord blowing, no analytical method has been obtained for the theoretical calculation of the relationship between the amount of blowing air and the increment of various aerodynamic coefficients. Exquisite reasons for the inflatable wing, the maximum lift coefficient increases
