Abstract: A method for improving the effectiveness of a labyrinth seal (40) between coannular components (22, 30) in a turbine engine (10) includes reconfiguring one of the components to provide means for receiving and retaining a replaceable brush seal (60) and installing the brush seal so that the seal bristles impede the leakage of air through an intercomponent gap (41). In the preferred embodiment the reconfiguring step is applied to a hollow, cylindrical barrel (30) and includes machining the barrel to reduce its axial length and its wall thickness and also includes attaching a retainer (52). The retainer cooperates with the barrel to define a groove (56) within which the brush seal is trapped radially and axially. The brush seal slides circumferentially within the groove to facilitate seal installation and removal. The invention dispenses with the need to carry out an expensive and time consuming replacement or renovation of the worn labyrinth seal.

Abstract translation: 一种用于改善涡轮发动机（10）中的管状部件（22,30）之间的迷宫式密封件（40）的有效性的方法包括重新组装所述部件中的一个以提供用于接收和保持可替换的刷密封件（60）并安装 刷密封，使得密封刷毛阻止空气通过组件间隙（41）的泄漏。 在优选实施例中，重新配置步骤被应用于中空圆柱形筒（30），并且包括加工筒以减小其轴向长度及其壁厚，并且还包括附接保持器（52）。 保持器与筒体配合以限定一个凹槽（56），刷子密封件径向和轴向地被夹在该凹槽内。 刷子密封件在槽内周向滑动以便于密封件的安装和拆除。 本发明不需要对磨损的迷宫式密封进行昂贵且耗时的更换或更新。
