Abstract: A gas turbine engine includes a first case, a second case, and a fastener. The first case has a first flange defining a first opening. The second case has a second flange defining a second opening. The second flange abuts the first flange. The fastener extends through the first opening and the second opening. The fastener defines a first bore that extends through a fastener head along an axis towards an outlet port defined by a fastener shank.

Abstract: A blade outer air seal (BOAS) for a gas turbine engine includes, among other things, a seal body having a radially inner face and a radially outer face that axially extend between a leading edge portion and a trailing edge portion. The BOAS includes a trough disposed on the radially inner face and an abradable seal received within the trough. The trough is open to expose a leading edge of the abradable seal to a core flow path of the gas turbine engine.

Abstract: An alignment tie rod device for connecting multiple components from generally opposite directions includes a shaft extending along a centerline. A first structure of the device includes opposing first and second rims and a base portion spanning between the rims. The base portion and rims define a channel that extends substantially normal to the centerline. A hole in the base portion is centered between the rims and communicates through the base portion for receipt of the shaft. An anti-rotation feature disposed operably within the channel is rigidly engaged to and projects radially outward from the shaft in diametrically opposed direction. The feature has diametrically opposite, arcuate, edges each having a radius of curvature that is substantially greater than a distance measured between the rims.

Abstract: A stator damper is disclosed. The stator damper has a body section and a damper finger. The body section rests against a stator assembly and a portion of each damper finger rests against a compressor casing. The stator damper is radially compressed between the stator assembly and the compressor casing. Thus, the stator damper exerts a radial force against the stator assembly. In this manner, relative motion of the stator assembly is damped.
Abstract translation: 公开了一种定子阻尼器。 定子阻尼器具有主体部分和阻尼指。 主体部分靠在定子组件上，并且每个阻尼器手指的一部分靠在压缩机壳体上。 定子阻尼器在定子组件和压缩机壳体之间径向压缩。 因此，定子阻尼器对定子组件施加径向力。 以这种方式，定子组件的相对运动被阻尼。
