    • A guide vane for use in a gas turbine engine fan section has an airfoil extending between a radially inner platform and a radially outer platform. The radially inner platform has a radially outwardly facing surface from which the airfoil extends and a radially inwardly facing underside. The airfoil has a trailing edge extending to a leading edge. The underside is attached to a mount bracket and a main rib extending from the underside of the platform adjacent the trailing edge and in a direction generally towards the leading edge, and merging into a top surface on the mount bracket. A pair of shoulders is formed on each of two circumferential sides of the rib. Each of the shoulders is spaced from each other at a point on the shoulders connected into the top surface of the mount bracket. The shoulders extend circumferentially toward each other and the under surface.
    • 用于燃气涡轮发动机风扇部分的引导叶片具有在径向内部平台和径向外部平台之间延伸的翼型件。 径向内部平台具有径向向外的表面,翼面从该表面延伸并且径向向内面向下的表面。 翼型件具有延伸到前缘的后缘。 下侧附接到安装支架和从平台的下侧延伸的主肋邻近后缘并且大致朝向前缘的方向,并且合并到安装支架上的顶表面中。 在肋的两个圆周侧的每一个上形成一对肩部。 每个肩部在连接到安装支架顶表面的肩部上的一个点处彼此间隔开。 肩部朝向彼此和下表面周向延伸。
