    • A replacement fan exit guide vane assembly (220) for installation between an inner case (116) and an outer case (118) of a gas turbine engine (100) includes an airfoil structure (222) having an outer end (224) and an inner end (226), a wedge structure (232) connected to the outer end (224) of the airfoil structure (222), a base plate (246) positioned between the outer end (224) of the airfoil structure (222) and the outer case (118), a conformable material (244), and a slip collar (230) having an opening (234) therethrough and a recess (236) formed along the opening (234). The airfoil structure (222) extends through the opening (234), and the recess (236) accepts the wedge structure (232) to create an interference fit between the slip collar (230) and the base plate (246). The conformable material (244, 244A) is disposed along the opening (234) and the recess (236) in the slip collar (230), and also along the baseplate (246), in order to provide dampening relative to the airfoil structure (232) and the wedge structure (232).
    • 用于安装在燃气涡轮发动机(100)的内壳体(116)和外壳体(118)之间的替换风扇出口导叶组件(220)包括具有外端(224)的翼型结构(222) 内端(226),连接到翼型结构(222)的外端(224)的楔形结构(232),定位在翼型结构(222)的外端(224)之间的基板(246)和 外壳(118),适形材料(244)和具有穿过其中的开口(234)的滑环(230)和沿着开口(234)形成的凹部(236)。 翼型结构(222)延伸穿过开口(234),并且凹部(236)接受楔形结构(232)以在滑动环(230)和基板(246)之间形成过盈配合。 顺应性材料(244,244A)沿滑动轴环(230)中的开口(234)和凹部(236)以及基板(246)设置,以便相对于翼型结构( 232)和楔形结构(232)。
