摘要:
A fan blade has a blade body, a composite rib and a cover. The blade body extends from a blade root to an opposed blade tip along a longitudinal axis. The blade body defines a leading edge and a trailing edge. A first airfoil surface extends from the leading edge to the trailing edge A pocket is defined between the leading edge, the trailing edge, the blade root, and the blade tip. The pocket has a bottom surface that opposes the first airfoil surface across the blade body. The composite rib is disposed in the pocket. The cover is mounted to the composite rib and the blade body to form a second airfoil surface opposed to the first airfoil surface.
摘要(中):
风扇叶片具有叶片主体,复合肋和盖。 叶片主体沿着纵向轴线从叶片根部延伸到相对的叶片尖端。 刀身限定前缘和后缘。 第一翼型表面从前缘延伸到后缘。在前缘,后缘,叶根和叶尖之间限定袋。 该袋具有横跨叶片主体与第一翼型表面相对的底表面。 复合肋设置在口袋中。 盖被安装到复合肋和叶片体上以形成与第一翼型表面相对的第二翼型表面。 p>
