用于涡轮机叶片的平背插入物
摘要：
本发明涉及一种用于涡轮机叶片的平背插入物，具体而言，涉及一种用于在发电中被使用的叶片(108)，其具有前缘(201)和后缘(203)。叶片(108)的第一壳部分(301)从前缘(201)延伸到后缘(203)。叶片(108)的第二壳部分(302)也从前缘(201)延伸到后缘(203)。叶片(108)的根部部分(209)定位成接近风力涡轮机(100)，并且顶部部分(207)从根部部分(209)延伸远离风力涡轮机(100)。后缘插入物(220)定位成在第一壳部分(301)和第二壳部分(302)之间、接近根部部分(209)。后缘插入物(220)具有在后缘(203)处在第一壳部分(301)第二壳部分(302)之间延伸并使其分隔开的表面(260)，以致于，插入物(220)提供了用于提高的叶片效率的大升力轮廓。
摘要（英）：

The invention relates to a flatback insert for turbine blades. A blade (108) for use in the generation of power has a leading edge (201) and a trailing edge (203). A first shell portion (301) of the blade (108) extends from the leading edge (201) to the trailing edge (203). A second shell portion (302) of the blade (108) also extends from the leading edge (201) to the trailing edge (203). A root portion (209) of the blade (108) is positioned proximate the wind turbine (100) and a tip portion (207) which extends from the root portion (209) away from the wind turbine (100). A trailing edge insert (220) is positioned between the first shell portion (301) and the second shell portion (302) proximate the root portion (209). The trailing edge insert (220) has a surface (260) which extends between and separates the first shell portion (301) from the second shell portion (302) at the trailing edge (203), such that the insert (220) provides a high lift profile for increased blade efficiency.
