摘要： A device for supplying flow across a combustor includes an axial fluid injector configured to circumferentially surround at least a portion of the combustor. An inner annular passage extends through the axial fluid injector and provides fluid communication through the axial fluid injector and into a first annular passage that surrounds the combustor. An outer annular passage extends through the axial fluid injector radially outward from the inner annular passage and provides axial flow into the first annular passage. A method for supplying flow to a combustor includes flowing a first portion of a working fluid through a first axial flow path and flowing a second portion of the working fluid through a second axial flow path.

摘要： In a combustor having an axis, a flow sleeve and a liner, a plurality of circumferentially spaced supports interconnect the upstream ends of the liner and flow sleeve to limit wear on the supports and accommodate relative thermal expansion of the liner and flow sleeve. Each support includes a flow sleeve stop having an angled surface, a groove and a female threaded aperture and a liner stop having a complementary angled surface, a rib and an enlarged opening. By inserting the liner axially through the open upstream end of the flow sleeve, the rib of the liner stop engages the slot of the flow sleeve stop. By passing a bolt having a spring through the enlarged opening of the liner stop and threading the bolt to the flow sleeve stop, the liner is biased for axial downstream movement to maintain the complementary inclined surfaces of the stops in contact with one another, thereby limiting wear and accommodating relative thermal expansion of the flow sleeve and liner.

摘要： A stator vane assembly for a gas turbine engine is provided which includes a plurality of stator vane segments and a seal ring. Each stator vane segment has an outer platform, an inner platform, and an airfoil extending between the platforms. The stator vane segments collectively form an annular structure. The seal ring includes an abradable bearing pad which extends out from an axial surface of the body of the seal ring. The seal ring is attached to a non-rotating member within the engine, positioned in close proximity to the stator vane segments. Contact, and consequent friction, between the individual stator vane segments and the abradable bearing pad causes the abradable bearing pad to abrade, thereby creating a sealing surface reflective of the opposing stator vane segments in contact with the abradable bearing pad.
