摘要：
An airfoil includes an airfoil body that defines a longitudinal axis. The airfoil body includes a leading edge and a trailing edge and a first side wall and a second side wall that is spaced apart from the first side wall to define a camber line there between. The first side wall and the second side wall join the leading edge and the trailing edge and at least partially define a cavity in the airfoil body. Multiple ribs extend longitudinally in the cavity and are laterally spaced apart from each other relative to the longitudinal axis. In at least one plane that is perpendicular to the longitudinal axis, each of the ribs connects the first side wall and the second side wall along respective minimum distance directions that are perpendicular to the camber line. At least two of the respective minimum distance directions are non-parallel.
摘要（中）：
翼型件包括限定纵向轴线的翼型件。 翼型本体包括前缘和后缘以及与第一侧壁间隔开的第一侧壁和第二侧壁，以在其间限定弧形线。 第一侧壁和第二侧壁连接前缘和后缘，并且在翼型体中至少部分地限定空腔。 多个肋在空腔中纵向延伸并且相对于纵向轴线彼此横向间隔开。 在垂直于纵向轴线的至少一个平面中，每个肋条沿垂直于弯度线的相应的最小距离方向连接第一侧壁和第二侧壁。 各个最小距离方向中的至少两个是不平行的。
