Abstract: A thermally compliant grommet assembly for a combustor includes first and second shells spaced apart from one another and a grommet having a tubular portion projecting into a hole in the second shell and defining a bore in fluid communication through the first and second shells. The grommet further has an oblong flange portion extending circumferentially around and projecting outward from the tubular portion. The oblong flange portion is located between and is in sealing contact with the first and second shells. At least one of the first and second shells is constructed and arranged to move between cold and hot states and generally along a thermal displacement path. The oblong flange portion is generally elongated along the path to maintain sealing contact with at least one of the shells as the shells move between the hot and cold states.
Abstract translation: 用于燃烧器的热适应索环组件包括彼此间隔开的第一和第二壳体和具有突出到第二壳体中的孔中的管状部分并且限定通过第一和第二壳体流体连通的孔的护环。 索环还具有沿圆周方向延伸并从管状部分向外突出的长圆形凸缘部分。 长方形凸缘部分位于第一和第二壳体之间并且与第一和第二壳体密封接触。 第一和第二壳中的至少一个被构造和布置成在冷和热状态之间移动并且通常沿着热位移路径移动。 长椭圆形的凸缘部分通常沿着路径细长，以在壳体在热和冷态之间移动时保持与至少一个壳体的密封接触。

Abstract: A combustor wall assembly has a heat shield and a supporting shell with a cooling cavity defined therebetween. A grommet generally includes a wall defining a dilution hole isolated from the cooling cavity, and a flange projecting radially outward from the wall and into the cooling cavity. The flange is space from the heat shield and a cooling channel is defined between the wall and the heat shield that communicates with the cavity for cooling the wall proximate to a combustion chamber.

Abstract: A combustor component defining a dilution hole configuration for a combustor wall assembly of a gas turbine engine has first and second dilution holes that communicate radially with one-another and with respect to respective centerlines of each dilution hole. In operation, each dilution hole forms a respective jet stream along respective centerlines for flowing cooling air into a combustion chamber.
Abstract translation: 限定用于燃气涡轮发动机的燃烧器壁组件的稀释孔构造的燃烧器部件具有第一和第二稀释孔，其相对于每个稀释孔的相应中心线径向连通。 在操作中，每个稀释孔沿着相应的中心线形成相应的喷射流，用于将冷却空气流入燃烧室。

Abstract: A disk-seal arrangement for a gas turbine engine rotor includes a blade retention disk having a longitudinally opening slot therein and a seal disk juxtaposed to said blade retention disk and a single anti-rotation tab received within the blade retention disk slot. The seal disk also includes a pair of balance slots disposed immediately adjacent the antirotation tab to offset the weight thereof for preserving rotor balance. A split ring is disposed longitudinally between the blade retention and seal disks for reacting longitudinal loading therebetween. The ends of the split ring seat against side surfaces of the antirotation between the split ring and the blade retention and seal disks.
