    • A replacement fan exit guide vane assembly for installation between an inner case and an outer case of a gas turbine engine includes an airfoil structure having an outer end and an inner end, a wedge structure connected to the outer end of the airfoil structure, a base plate positioned between the outer end of the airfoil structure and the outer case, a conformable material, and a slip collar having an opening therethrough and a recess formed along the opening. The airfoil structure extends through the opening, and the recess accepts the wedge structure to create an interference fit between the slip collar and the base plate. The conformable material is disposed along the opening and the recess in the slip collar, and also along the baseplate, in order to provide dampening relative to the airfoil structure and the wedge structure.
    • 用于安装在燃气涡轮发动机的内壳体和外壳体之间的替换风扇出口导向叶片组件包括具有外端和内端的翼型结构,连接到翼型结构的外端的楔形结构,底座 位于翼型结构的外端和外壳之间的板,适形材料和具有穿过其的开口的滑环和沿着开口形成的凹部。 翼型结构延伸穿过开口,并且凹槽接受楔形结构以在滑环和底板之间形成过盈配合。 顺应性材料沿着开口和滑动套环中的凹部以及基底板设置,以便相对于翼型结构和楔形结构提供阻尼。
