20110206519 | FASTENER APERTURE HAVING AN ELONGATED GEOMETRY - An apparatus includes a substrate having one or more fastener apertures that extend therethrough. Each fastener aperture has a centerline and includes first and second circular segmented regions and a central channeled region. Each circular segmented region has a diameter and a segment length that extends along the centerline, wherein the segment length is greater than one-half the diameter. The central channeled region extends along the centerline between the first and the second circular segmented regions. The central channeled region has a height that is less than the diameter of the first and the second circular segmented regions. | 08-25-2011 |
20130149133 | STATOR VANE SHROUD HAVING AN OFFSET - An example stator vane assembly of a turbomachine includes a shroud having a leading edge, a trailing edge, and at least one circumferential edge. The leading edge is circumferentially offset relative to the trailing edge when installed within the turbomachine. | 06-13-2013 |
20130177400 | STATOR VANE INTEGRATED ATTACHMENT LINER AND SPRING DAMPER - A stator subassembly includes an array of circumferentially arranged stator vanes. An attachment liner secures the stator vanes to one another to provide the subassembly. A damper spring is integral with the attachment liner and is provided between the array and an outer case, which supports the array. The damper spring is configured to bias the array radially inwardly from the outer case. | 07-11-2013 |
20130177401 | STATOR VANE SPRING DAMPER - A stator subassembly includes an array of circumferentially arranged stator vanes. A damper spring is provided between the array and an outer case, which supports the array. The damper spring is configured to bias the array radially inwardly from the outer case. | 07-11-2013 |
20130209248 | Anti-Rotation Stator Segments - A stator assembly for a turbofan gas turbine engine is disclosed. The stator assembly is coupled to a shroud of the engine. The stator assembly includes an endless case fixedly coupled to the engine shroud. The case includes a forward portion, an aft portion and a central portion disposed therebetween. The case extends about an axis of the engine. The forward and aft portions of the case include rails that extend towards each other and form forward and aft pockets with the central portion respectfully. The stator assembly also includes a locking stator segment. The locking stator segment includes a shroud that includes a forward hook and a pair of aft hooks with a platform disposed therebetween. The forward and aft hooks are retained in the forward and aft pockets of the case respectfully. | 08-15-2013 |
20130302151 | Stator Assembly - A stator assembly or a stator stage is disclosed. The stator assembly includes an endless case that is coupled to or includes at least one lug for engaging an anti-rotation stator segment. The anti-rotator segment includes one curved side edge and one straight or linear side edge. The case also accommodates a plurality of middle stator segments, each having curved side edges on both sides. Finally, a third type of stator segment is a “neighbor” stator segment with one curved side edge and one linear side edge that abuttingly engages the linear side edge of the anti-rotation stator segment. The straight or linear side edges of the anti-rotation stator segments and the neighbor stator segments enable an endless case to be loaded with stator segments from an axial direction. None of the stator segments need to be installed from a radial direction. | 11-14-2013 |
20140093363 | LINER AND METHOD OF ASSEMBLY - An assembly includes a plurality of vanes, a forward liner segment, and an aft liner segment. The forward liner segment and the aft liner segment are mounted to the plurality of vanes and each segment comprises an arc of less than 360° in length. | 04-03-2014 |
20150240663 | LINER LOCK SEGMENT - An assembly includes a first vane pack, a second vane pack, and a liner lock segment. The first vane pack has a plurality of vanes each vane with an airfoil, a platform, and forward and aft mounting hooks. The second vane pack has a plurality of vanes each vane with an airfoil, a platform, and forward and aft mounting hooks. The second vane pack is disposed to abut the first vane pack. The liner lock segment is disposed between the first vane pack and the second vane pack. | 08-27-2015 |
