| 摘 要： | 利用有限体积法离散可压缩Euler方程,计算了带5种不同类型翼梢小翼的全机高速巡航外形.重点研究了不同小翼对飞机横航向静稳定性、机翼压力中心移动量和侧滑时滚转力矩系数随迎角变化的影响规律.研究结果表明:(1)翼梢小翼均不降低飞机的横向静稳定性,都将降低飞机的航向稳定性；(2)翼梢小翼均使机翼压力中心向外移动,小后掠角的...

| Abstract: | This paper has calculated the high-speed cruising aircraft shape with five different winglets by using the discreted compressible Euler equation,and studied the effect laws of the static lateral-directional stability,dis-placement of wing pressure center and the roll coefficient vs angle of attack during sideslip.The results show:(1)Winglets would increase the static lateral stability and decrease the static directional stability;(2)Winglets would make the wing pressure center move toward outside,the displa... |
