摘要： An impingement panel (130, 134) having an impingement plate (136) disposed along an exterior surface (131, 135) of one of the inner liner segment or the outer liner segment. The impingement plate (136) defines a plurality of impingement apertures (139) that direct coolant in discrete jets towards the exterior surface (131, 135) of the inner liner segment or the outer liner segment. The impingement panel (130, 134) includes an inlet portion (140) that extends from the impingement plate (136) to a collection duct (142). The impingement panel (130, 134) further includes a plurality of supports (194) spaced apart from one another. The plurality of supports (194) extend between, and are coupled to, the inlet portion (140), the collection duct (142), and the impingement plate (136)

摘要： A system includes an engine case (102) for a gas turbine engine defined around a longitudinal axis. A combustor (108) is housed in the space inside the engine case (102). The combustor (108) includes an inner annular wall (110) and an outer annular wall (112) radially outboard from the inner annular wall (110). The inner annular wall (110) includes a first rail (114) on an upstream end thereof with a radially outward opening slot (116). The outer annular wall (112) includes a second rail (118) on an upstream end thereof. The combustor (108) includes a plurality of circumferentially spaced apart dome liners extending from the first rail (114) to the second rail (118). A plurality of fuel injector components (122) can be assembled across the first and second rails to form a combustor dome together with the dome liners at an upstream end of a combustion space defined between the inner and outer annular walls of the combustor (108).

摘要： A gas turbine engine (20) includes an annular combustion chamber (40) and an injector ring (42) that is configured to introduce a hydrogen and gas mixture into the combustion chamber (40). The injector ring (42) may include a hydrogen manifold cavity (52), hydrogen feed conduits (54) that extend off of the hydrogen manifold cavity (52) and open into a mixing region (56) at an axial end of the injector ring (42), and gas feed conduits (60) that also open into the mixing region (56) to supply gas that mixes with the hydrogen. The hydrogen feed conduits (54) may be tangentially-sloped, and the gas feed conduits (60) may be radially and tangentially sloped.

摘要： A gas turbine engine includes an annular combustion chamber (7) and a plurality of combustors (6) communicating with the annular combustion chamber (7). Each combustor (6) defines a respective gas flow path (20) along a respective combustor axis (C) and has a first combustor stage (6a) and a second combustor stage (6b), sequentially arranged along the respective gas flow path (20). The second combustor stages (6b) of the combustors (6) are configured to discharge into the annular combustion chamber (7).
