摘要： It has been found that in a dry low NOx combustor of the type having an upstream combustion chamber and a downstream combustion chamber interconnected by a venturi section, the fuel-air ratio and uniform fuel-air mixing can be improved by providing an annular shield upstream of the venturi region. The shield is impingement cooled through the venturi and provision is made for dumping cooling air farther downsteam in the downstream combustion chamber. With the aforesaid improvements in mind, the upstream combustion chamber is provided with first and second inner liners which are also impringement cooled an which provide combustion air farther upstream into the upstream combustion chamber to further improve fuel-air mixing and to maintain the desired fuel-air ratio.

摘要： A method of making a dome plate for a gas turbine engine combustor includes forming an annular body and forming a plurality of swirler openings in the annular body. Then, an array of impingement cooling holes and an array of blow-off holes are electrically discharge machined into the annular body adjacent to each swirler opening. For each one of the plurality of swirler openings, the corresponding array of impingement cooling holes and the corresponding array of blow-off holes are machined in a single electrical discharge machining operation. This results in an annular dome plate having radially outer and inner curved corners that define a single radius of curvature. The blow-off holes are located in at least one of the outer and inner curved corners.

摘要： A combustor liner for use in a gas turbine engine includes a first annular panel section having a first cooling nugget formed at one end thereof and a second annular panel section having a second cooling nugget formed at one end thereof. A first row of cooling holes is formed in the first cooling nugget, and a second row of cooling holes is formed in the second cooling nugget. The second row of cooling holes is arranged in a preferential cooling pattern including a plurality of arrays, each array has a first set of cooling holes having a first diameter and a second set of cooling holes having a second diameter that is smaller than the first diameter. The cooling hole arrays are preferably arranged to minimize tooling set-ups and thereby reduce cost. At least one igniter tower is formed in the first annular panel section and is circumferentially aligned with one of the second sets of cooling holes.

摘要： A dome assembly for a gas turbine engine combustor includes an annular combustor dome with a substantially annular flat dome plate and at least one circular opening in the dome plate. A seal plate flange with a flat aft facing surface has a central ring circumscribed about a centerline axis and extends aftwardly from the seal plate flange. The central ring is disposed through the circular opening in the dome plate and the central ring includes a central bore coaxially aligned with the circular opening. A baffle has a cylindrical tubular mounting portion extending upstream through the central bore and is fixedly joined to the seal plate and a flare portion extending aft from the seal plate flange. A carburetor including an air swirler having an annular exit cone is joined to the baffle with the exit cone disposed within the cylindrical tubular mounting portion of the baffle. An aft end of the central ring is joined to the dome plate by a swage joint. The seal plate flange is preferably flat and has a rounded corner triangular shape with three wings having radially outer arcuate edges with respect to the centerline axis. Legs extend axially aftwardly from the aft facing surface of the seal plate flange wherein each of the legs is located about midway between each two of the three wings and the seal plate flange is joined to the dome plate by second tack welds between the legs and the dome plate.
