摘要
自然层流机翼是最简单而有效的减阻技术。本文结合作者新近的工作,着重论述了后掠翼上自然层流边界层转捩的估算方法和转捩准则的选择并讨论了压力分布对转捩的影响。最后还提出了若干建议供读者参考。
NLE airfoil is the simplest and efficient drag reductiontechnique.This paper reviewed in detail on the predicting method ofthe transition on a swept wing and the selection of transition criterion.Meanwhile.simply discussed the influence of the pressure distributiontype and the turbulent level as well as noise on the transition.Finallysome conclusions are provided for designer's reference.
