研究表明，侧滑使机翼迎风侧涡绞合推迟，涡提前破裂，背风侧正好相反。
Results show that sideslip makes twisting of vortices at upwind side delayed, but bursting of.
中等厚度的防风林在背风侧可在20倍于树高的距离而在迎风侧则在3倍于树高的距离上减小风速10%以上。
A medium-thick shelterbelt can reduce wind velocity by more than 10 percent to a distance of 20 times the tree height on the leeward side and three times the height to the windward.
改型进气道减小了输出轴背风侧的分离和迎风侧的转弯损失，使其既保持了高总压恢复系数，且畸变指数最大降低了74%。
By modifying, the separation zone behind the shaft and turn loss at upwind side are all reduced. Modifying inlet maintains high pressure recovery, and the distortion index is reduced by 74% at most.
