| 摘 要： | 前掠翼布局由于其潜在的优越性,在未来战斗机的研究设计中将占有日益重要的地位.本文通过风洞测力实验,研究了近距鸭翼相对于前掠主机翼的高度对布局纵向气动性能的影响.实验结果表明:随着主机翼前掠角的增大,近距鸭翼布置高度逐渐增加可获得较好的气动特性.

| Abstract: | Forward-swept configuration plays a more and more prominent role in the design of modern fighters because of its potential advantages.Force measurement in a low-speed wind tunnel was conducted to investigate the effects of the height of close canard wing on the longitudinal characteristics of a forward-swept configuration.The results indicate that it is more favorable for the aerodynamic characteristics to equip a higher close canard wing together with forward-swept angle of main wing increasing. |

| Keywords: | forward-swept wing close canard wing lift drag lift-to-drag ratio |
