摘要
油流试验表明,迎角α=8°时,小边条机翼的外翼上就出现分离区。通过加翼刀或锯齿或缩短翼展都可以抑制分离区的发展。试验表明,采用加双翼刀和缩短翼展的组合方案,可以使升力曲线随迎角的变化直到α=16°都是线性的。
Oil flow test has been shown that flow separation appears at the outer part of a wing with a small strake about at α =8°.The separation leads to the decrease of slope of lift curve.By adding a fence or a saw tooth or reducing a wing span,the separation could be supressed.The test result has shown that the variation of the lift with the incidence is linear up to α =16° by adding 2 fences at each side of the wing and reduceding the wing span.
