20130327048 | COMBUSTOR LINER WITH CONVERGENT COOLING CHANNEL - A combustor liner includes a heat shield, a shell, a series of trip strips, and a series of projecting walls. The heat shield has a shield cold side. The shell is attached to the heat shield and includes a shell hot side facing the shield cold side, a shell cold side facing away from the shield cold side, and a row of cooling holes. The trip strips run parallel to each other and all project from the shield cold side the same distance. Each projecting wall runs parallel to, and opposite of, a corresponding trip strip and projects from the shell hot side such that the distance to which each projecting wall projects is greater for projecting walls farther from the row of cooling holes, creating successive gaps between the projecting walls and corresponding trip strips that decrease from the row of cooling holes to create a convergent channel. | 12-12-2013 |
20130327049 | COMBUSTOR LINER WITH REDUCED COOLING DILUTION OPENINGS - A combustor liner is arcuate in shape and defines an axis and a circumferential direction. The combustor liner includes a first row of dilution openings and a second row of dilution openings. The first row runs in the circumferential direction. The second row runs parallel to the first row and is axially spaced from the first row. Each dilution opening of the second row overlaps in an axial direction a portion of each of two adjacent dilution openings of the first row. | 12-12-2013 |
20130327056 | COMBUSTOR LINER WITH DECREASED LINER COOLING - A shell for a combustor liner includes a cold side, a hot side, a row of cooling holes and a jet wall. The jet wall projects from the hot side for creating a wall shear jet of increased velocity cooling flow in a tangential direction away from the row of cooling holes and along an adjacent heat shield cold side wall. | 12-12-2013 |
20130327057 | COMBUSTOR LINER WITH IMPROVED FILM COOLING - A heat shield for a combustor liner includes first linear film cooling slots through the heat shield and second linear film cooling slots through the heat shield. The first linear film cooling slots are run in a row and each of the first linear film cooling slots is angled from the row in a first direction. The second linear film cooling slots also run in the row and each of the second linear film cooling slots is angled from the row in a second direction opposite the first direction. The second linear film cooling slots alternate with the first linear film cooling slots in the row. The first and second linear film cooling slots are connected to form a single, multi-cornered film cooling slot. | 12-12-2013 |
20130340437 | TURBINE ENGINE COMBUSTOR WALL WITH NON-UNIFORM DISTRIBUTION OF EFFUSION APERTURES - A turbine engine combustor wall includes support shell and a heat shield. The support shell includes shell quench apertures, first impingement apertures, and second impingement apertures. The combustor heat shield includes shield quench apertures fluidly coupled with the shell quench apertures, first effusion apertures fluidly coupled with the first impingement apertures, and second effusion apertures fluidly coupled with the second impingement apertures. The shield quench apertures and the first effusion apertures are configured in a first axial region of the heat shield, and the second effusion apertures are configured in a second axial region of the heat shield located axially between the first axial region and a downstream end of the heat shield. A density of the first effusion apertures in the first axial region is greater than a density of the second effusion apertures in the second axial region. | 12-26-2013 |
20140083100 | GAS TURBINE ENGINE COMBUSTOR - A swirler assembly for a gas turbine engine includes an outer annular injector which at least partially surrounds an inner injector. | 03-27-2014 |
20140090402 | Combustor Bulkhead Assembly - A heat shield is disclosed. The heat shield may comprise a body having a back surface and an opposite front surface, wherein an opening in the body communicates through the front and back surfaces. The heat shield may further comprise at least one radial rail disposed on the back surface and extending radially outward from the opening for directing cooling air flow. | 04-03-2014 |
20140096528 | Cooling for Combustor Liners with Accelerating Channels - A combustor liner which reduces cooling flow to a combustion chamber and augments pressure drop split between impingement holes and effusion holes is disclosed. The combustor liner may further include accelerating channels, trip strips, pedestals, and cone-shaped effusion holes to provide further cooling of the liner. The combustor liner may reduce NOx production and the temperature of the combustion chamber of a gas turbine engine or the like. | 04-10-2014 |
20140137559 | GAS TURBINE ENGINE COMBUSTOR WITH INTEGRATED COMBUSTOR VANE - A combustor section for a gas turbine engine includes a combustor vane which extends at least partially into a combustion chamber. | 05-22-2014 |
20140216044 | GAS TURBINE ENGINE COMBUSTOR HEAT SHIELD WITH INCREASED FILM COOLING EFFECTIVENESS - A heat shield for a gas turbine engine includes a hot side with one or more raised features that extend therefrom. | 08-07-2014 |
20140338336 | GAS TURBINE ENGINE COMBUSTOR WITH INTEGRATED COMBUSTOR VANE - A combustor section for a gas turbine engine includes a combustor vane which extends at least partially into a combustion chamber. | 11-20-2014 |
