Abstract:
Brennkammervorrichtung, umfassend einen Brennraum (12), welcher durch einen Innenmantel (14; 14') begrenzt ist, wobei der Innenmantel (14; 14') ein fluiddurchlässiges Strukturmaterial (32) aufweist, und wobei der Innenmantel (14; 14') mindestens einen Strömungskanal (42) mit einem Strömungsbereich (54) für Fluid umfasst, dadurch gekennzeichnet, dass der Innenmantel (14; 4') eine fluidundurchlässige Innenmantelschicht (62) aufweist, welche an einer Seite (58) des Strukturmaterials (32) des Innenmantels (14; 14') angeordnet ist, wobei die Seite (58) den Strömungsbereich (54) des mindestens einen Strömungskanals (42) zumindest bereichsweise begrenzt, und wobei die fluidundurchlässige Innenmantelschicht (62) mindestens eine Öffnung (64) aufweist, mittels welcher eine fluidwirksame Verbindung zwischen dem Strömungsbereich (54) des mindestens einen Strömungskanals (42) und dem fluiddurchlässigen Strukturmaterial (32) des Innenmantels (14; 14') herstellbar ist.
Abstract:
A component for a turbine engine and method for providing a cooling film on a turbine engine component, including an outer wall separating a hot fluid flow from a cooling fluid flow, using the cooling fluid flow to cool the engine component. A region in the component can include a plurality of film holes with a porous material to meter the flow of cooling fluid provided from the engine component.
Abstract:
An assembly for a turbine engine includes a combustor wall. The combustor wall includes a shell, a heat shield and an annular land. The heat shield is attached to the shell. The land extends vertically between the shell and the heat shield. The land extends laterally between a land outer surface and an inner surface, which at least partially defines a quench aperture in the combustor wall. A lateral distance between the land outer surface and the inner surface varies around the quench aperture.
Abstract:
A combustor for a turbine engine is provided that includes a combustor wall. The combustor wall includes a shell and a heat shield, which is attached to the shell. One or more cooling cavities are defined between the shell and the heat shield, and fluidly couple a plurality of apertures defined in the shell with a plurality of apertures defined in the heat shield. The apertures in the heat shield include a first aperture and a second aperture. An angle of incidence between the first aperture and a surface of the heat shield is different than an angle of incidence between the second aperture and the surface.
Abstract:
A liner panel for use in a gas turbine engine. The liner panel has a hot side and a cold side. The liner panel includes a rail extending from the cold side and a multiple of studs extending from the cold side. At least one of the multiple of studs extends from, in part, the rail.
Abstract:
A liner panel within a gas turbine engine includes a perimeter rail that defines a first height from a cold side. The liner panel also includes an intermediate rail that defines a second height from the cold side, where the second height is less than the first height.
Abstract:
A combustor wall is provided for a turbine engine. The combustor wall includes a combustor shell and a combustor heat shield that is attached to the shell. The heat shield includes a first panel and a second panel that sealingly engages the first panel in an overlap joint. A cooling cavity extends between the shell and the heat shield and fluidly couples a plurality of apertures in the shell with a plurality of apertures in the heat shield.
Abstract:
A liner panel for a combustor of a gas turbine engine includes a multiple of heat transfer augmentors. At least one of the multiple of heat transfer augmentors includes a hemi-spherical protuberance.
Abstract:
A combustor having U-shaped cooling channels is disclosed. The combustor may include a shell having an impingement hole, a liner spaced from the shell and having an effusion hole; a first partition spanning between the shell and the liner, a second partition spaced from the first partition and spanning between the shell and the liner; and a U-shaped channel defined between the shell and the liner and defined in part by the wall, the channel having upstream and downstream ends both adjacent the first partition and separated by the wall, wherein the impingement hole communicates with the upstream end and the effusion hole communicates with the downstream end.
