Abstract: An attachment interface assembly for a gas turbine engine has a component configured for attachment to an engine static structure. A fastener has a threaded body portion and an enlarged head portion. The threaded body portion is inserted through aligned holes in the component and engine static structure. A clip has a center opening that receives the threaded body portion such that the clip is positioned between the enlarged head portion and the component.

Abstract: A shaft interlock system may have an a interlocking piston that translates a movable locking apparatus configured to interface with a turbine shaft having a fixed locking apparatus. The movable locking apparatus may engage and disengage the fixed locking apparatus. When the movable locking apparatus is engaged with the fixed locking apparatus, the turbine shaft is only able to turn in one direction. When the movable locking apparatus is disengaged from the fixed locking apparatus, the turbine shaft is able to turn in both directions. In this way, a turbine shaft can be prevented from reverse rotation.

Abstract translation: 轴联锁系统可以具有互锁活塞，该互锁活塞使构造成与具有固定锁定装置的涡轮轴相接合的可移动锁定装置平移。 可动锁定装置可以接合和分离固定的锁定装置。 当可移动锁定装置与固定锁定装置接合时，涡轮轴只能沿一个方向转动。 当可动锁定装置与固定锁定装置分离时，涡轮轴能够沿两个方向转动。 以这种方式，可以防止涡轮轴反向旋转。

Abstract: A bearing housing may include a main body integrated with a bearing receiving portion. A bearing retention stop may extend from the main body and include a plurality of access cutouts for facilitating the removal of a bearing from the bearing housing without causing damage to the bearing.
