A combustor for a gas turbine engine that facilitates reducing combustor chamber dump pressure losses to improve combustor and engine performance is described. The combustor includes a diffuser that diffuses airflow directed into the combustor. The diffuser includes an outer wall, an inner wall, and a plurality of splitter vanes between the outer wall and the inner wall. The splitter vanes are spaced radially apart, and each is spaced radially from a respective diffuser wall such that an outer passage, an inner passage, and a central passage are defined by the splitter vanes.

A fuel nozzle including a nozzle stem having an annular overhang and a heat shield secured to the overhang is described. More specifically, and in one embodiment, the nozzle stem includes an upstream end and a downstream end. The annular overhang is intermediate to the upstream end and the downstream end of the stem. The heat shield includes a first end and a second end, and the heat shield is welded to the annular overhang at the heat shield first end. An annular air gap is between the nozzle stem and the heat shield.

A shroud support for use in a gas turbine engine having a foot section which is equipped with two continuous rails which extend in a circumferential manner forming a gap between them. The rails contact a foot section of a shroud and prevent cooling air from leaking from a plenum formed by the shroud support to a position to the aft of the foot sections of the shroud and shroud support.

Airtight shroud support rail and method for assembling in turbine engine

An assembly for preventing cooling air from leaking from a plenum region formed by a shroud support and a shroud. The shroud support and shroud being so connected as to form a gap which leads from the plenum region to a cavity. The cavity being located in the forward hook region of the shroud support. A rope seal fills the cavity and prevents cooling air from leaking into the cavity causing the cooling air to remain in the plenum region.
