同時(shí)在葉片整體性能上，也進(jìn)行了檢驗(yàn)，如表3所示。表中數(shù)據(jù)表明，碳纖維替代玻璃纖維，主梁利用彎扭耦合進(jìn)行設(shè)計(jì)，在鋪層平均厚度減小11.33%的情況下，葉片在結(jié)構(gòu)性能上仍有全面的提高。

 
3 小結(jié)
    彎扭耦合運(yùn)用到葉片設(shè)計(jì)將是大勢(shì)所趨，其技術(shù)將會(huì)逐漸成熟。本文主要對(duì)彎扭耦合設(shè)計(jì)在葉片主梁上的運(yùn)用做了初步探討對(duì)彎扭耦合控制參數(shù)進(jìn)行了研究，推導(dǎo)出了單向?qū)雍习遄詈?jiǎn)潔的耦合控制參數(shù)的表達(dá)式，并從理論上對(duì)彎扭耦合控制參數(shù)的變化范圍進(jìn)行了計(jì)算。計(jì)算表明，在一定鋪層角度范圍內(nèi)，彎扭耦合程度對(duì)材料十分敏感。主梁上碳纖維替代玻璃纖維，并引入彎扭耦合設(shè)計(jì)將會(huì)使葉片在整體性能有較大提高。
