| 摘 要： | 大展弦比机翼有明显的升/阻(L/D)优势。但随着机翼展弦比的增大,在机翼结构重量控制条件下,机翼成柔性机翼,飞行中机翼的弹性变形量随速压(1/2ρV2)增大而增大,出现了严重的气动/结构耦合的问题。本文阐述了耦合问题的成因和解决途径,为特大展弦比机翼飞机(长航时无人机)的设计提供参考。

| Abstract: | Wings of big aspect ratio has obvious advantage of lift and drag.As increment of wing aspect ratio and under the condition of weight control on wing structure,since the wing is flexible and its elastic deformation during flight will incresse along with the increment of the dynamic pressure,from which serious dynamic/structure coupling problems are caused. This paper describes the cause and settlement ways of coupling problems.It further presents the reference on designing aircraft with extreme big aspect ratio(extending the duration of UAV) |
