    Abstract: A gas turbine engine (20) includes a combustor (56) disposed about an engine central axis (A) and a circumferential row of vanes (72) adjacent an exit region (70) of the combustor (56). The combustor (56) includes a combustor wall (62, 64) and a combustion chamber (66). The combustor wall (62, 64) has a lip (65) at the exit region (70). Each vane (72) includes a platform (74, 76) and an airfoil section (78) extending from the platform (74, 76). The forward edges (74a) of the platforms (74, 76) are adjacent the lip (65) of the combustor wall (62, 64). The lip (65) defines a first annular slot (82) and the forward edges (74a) of the vanes (72) collectively define a second annular slot (84). The first and second annular slots (82, 84) together define an annular seal slot (86). An annular feather seal (88) is entrapped in the annular seal slot (86) between the combustor wall (62, 64) and the platform (74, 76).

    Abstract: A heat shield panel (300) for use in a gas turbine engine combustor (56) is disclosed. The heat shield panel (300) includes a hot side (230), a cold side (232) spaced from the hot side (230), and a rail (304, 306, 308, 310) disposed about a periphery of the cold side, the rail including a first rail member (308) having a first length (328) extending along the panel, a first height (h) extending from the cold side (232), and a first thickness (350) that varies along the first length (328).

    Abstract: A combustor panel (110) may include an attachment feature (106) having a central longitudinal axis (125) and extending from a cold side (131) of the combustor panel (110). The attachment feature (106) may include a tip portion (122) and a base portion (121) and the attachment feature (106) may be configured to extend through a combustor shell (140) such that the tip portion (122) is disposed outward of a diffuser-facing side of the combustor shell (140). The base portion (121) may be configured to be disposed between the cold side (131) of the combustor panel (110) and the diffuser-facing side of the combustor shell (140). The attachment feature (106) may define a core passage (124) extending from an inlet opening (123) defined on the tip portion (122) and extending partially through the attachment feature (106) to terminate within the attachment feature (106). The attachment feature (106) may also define an offshoot passage (126) extending from the core passage (124) to an outlet opening (127) defined on the base portion (121).
