海上風電：葉片究竟會變多大？

Editor's Commentary

Additional coverage of composites in the wind energy market in this issue include: "Windpower 2009 Highlights"The American Wind Energy Assn.'s (Washington, D.C.) show confirmed wind energy’s status as a recession-proof market for composites, but blade manufacturers were put on notice about the need to automate. "Work in Progress: Automating wind blade manufacture"Recent technology announcements portend a new era of more efficient blade production. "Engineering insights: Challenged to engineer retrofit blades"Myriad interrelated design factors are considered in new blades for turbines originally built for high-wind regimes.


2008 was another banner year for the wind energy industry. Recent data suggest that global installation of new wind turbines last year exceeded 28,000 megawatts (MW) of rated capacity (roughly 19,000 turbines), worth approximately $48.9 billion USD (

估計碳纖維很快就要上場了。

尤其是在剛性驅動的超大型葉片設計當中

又Repower 制造，（現(xiàn)為SUZLON了）

PS：最近Repower接5MW風機的單接了不少。看來經過幾年的原型機運營，開始獲得認可了。

不同葉片設計及其質量對比

LM的Super root technology 和Super blade technology 經過幾年折騰，看來不是吹的。

碳纖維看來功不可沒。在50米以上的葉片當中，碳纖維的部分使用和設計的改進，可以帶來三分之一的質量減輕！[s:7]


TPI 的創(chuàng)新概念葉片設計也是相當的雷人。居然把50米的葉片重量拉到了10噸一下。

不知道我們什么時候能上50M 的，哎資金有限啊，市場有限??！GE快點多接單子[s:1]

。。天哪。。。壯觀啊。。。。。。額額。。。

我看見2.5mw的機艙罩就覺得好大了，要是10mw的話是不是要一個車間那么大了啊。。。。長見識了。。嘿嘿。。。

碳纖維沒那么容易用上的 [s:1] ，目前大部分碳纖維的原料聚丙烯晴纖維價格已經是國內的王牌玻璃纖維價格的幾倍了，而且碳纖維制造過程能耗特高，產品價格是玻璃纖維的十幾倍到二十幾倍，估計只有超大的葉片主要承載部分可以用，例如主梁，當然碳?；炀幐昧?。 [s:1]
