风力涡轮机叶片及制造该叶片的方法
摘要：
本发明涉及风力涡轮机叶片及制造该叶片的方法，具体而言，提供了一种风力涡轮机叶片(112)。该风力涡轮机叶片包括根部部分(120)、尖端部分(122)以及从根部部分向尖端部分径向地向外延伸的翼型部分(121)。该叶片还包括从根部部分经由翼型部分的至少一部分径向地向外延伸的翼梁罩(150)。翼梁罩的至少一部分大致纵向地定向，并通常线性地从翼梁罩的第一端(155)向翼梁罩的第二端(157)延伸。叶片还包括从翼梁罩延伸的至少一个翼梁罩延伸部分(158)。翼梁罩延伸部分的至少一部分相对于翼梁罩非线性地定向。
摘要（英）：

A method of forming a wind turbine blade includes forming a root portion, a tip portion, and an airfoil portion extending radially outward from the root portion to the tip portion. The method also includes forming a spar cap extending radially outward from the root portion through at least a portion of the airfoil portion. At least a portion of the spar cap is oriented substantially longitudinallyand extends generally linearly from a first end of the spar cap to a second end of the spar cap. The method also includes forming at least one spar cap extension that extends from the spar cap, wherein at least a portion of the spar cap extension is oriented nonlinearly relative to the spar cap.
