A combustion cylinder mounting method, wherein a preparation step, a first contact maintenance step, a second contact maintenance step, and a combustion cylinder fixing step are executed. In the preparation step, a combustion cylinder mounting jig equipped with a spacer portion capable of maintaining a predetermined spacing between a first combustion cylinder and a second combustion cylinder adjacent to each other in the circumferential direction is prepared. In the first contact maintenance step, the spacer portion is brought into contact with the first combustion cylinder attached to the stationary portion of a casing. In the second contact maintenance step, the second combustion cylinder is brought into contact with the spacer portion. In the combustion cylinder fixing step, the second combustion cylinder is attached to the stationary portion while the first combustion cylinder and the second combustion cylinder are in contact with the spacer portion.

The invention relates to an air/fuel injection system for a turbomachine, comprising: —an injector comprising a duct and an injection nose, arranged inside said duct, which extends from upstream to downstream along a longitudinal axis; —a mixer device comprising a bowl comprising an annular inlet, forming the inlet of the mixer device, from which there extends a conical portion flared in the downstream direction, said mixer device being arranged downstream of the injection nose; the injection system being characterized in that the injector comprises an air-injection annulus extending from the duct and from which there extends a connection ring comprising a divergent portion, said ring being arranged externally around the annular inlet of the mixer device.

A method comprising applying braze to a joint location of two work pieces and applying local heating to the joint location of the two work pieces until braze melting temperature is achieved to melt the braze while maintaining temperature of more remote portions of each work piece. The method includes reducing heating of the braze to form a braze joint joining the joint location of the two work pieces.

A method includes joining a fuel plurality of injection components to a fuel manifold, wherein for each fuel injection component in the plurality of fuel injection components, a metallic joint is formed joining and sealing the fuel injection component to the manifold. A system includes a fuel manifold. A plurality of fuel injection components are connected in fluid communication with the fuel manifold with metallic joints sealing between each of the plurality of fuel injection components and the fuel manifold to prevent leakage from between the manifold and the plurality of fuel injection components.

A cartridge for attachment to the inner surface of a single-walled combustion liner of an annular combustor is provided. The cartridge includes at least one chute projecting into the combustion chamber for a counter swirl effect for improved fuel/air mixing in the combustion chamber and at least two studs projecting through associated stud holes in the liner. A method for attaching a cartridge to the inner surface of a single-walled combustion liner is also provided.

A combustor may comprise an outer combustor panel and an inner combustor panel radially inward of the outer combustor panel. A bulkhead panel may extend radially between the outer combustor panel and the inner combustor panel. An outer spacer may be located between an outer flange of the bulkhead panel and the outer combustor panel. An inner spacer may be located between an inner flange of the bulkhead panel and the inner combustor panel.

A combustor liner assembly includes a first liner panel that has a first forward end and a first aft end. A second liner panel has a second forward end and a second aft end. A support band has a plurality of circumferentially spaced holes. The support band is arranged between the first liner panel and the second liner panel. The support band has a protrusion with a first angled surface and a second angled surface. The first angled surface is in engagement with the first aft end and the second angled surface in engagement with the second forward end.

A fuel supply nozzle unit includes a fuel supply nozzle, a rear end and an end plate. The fuel supply nozzle includes a front end that has a plurality of fuel supply holes. The rear end extends from the front end and is formed with a threaded portion on its outer surface. The end plate is connected to the rear end and is formed with a plurality of threaded holes.

A gas turbine engine and combustor assembly are provided, the combustor assembly including a first liner and a second liner together defining at least in part a combustion chamber, wherein the first liner and the second liner are separated by a gap along the longitudinal direction, and wherein the first liner is forward of the second liner relative to a flow of fluid through the combustion chamber along the longitudinal direction, and wherein the gap is extended along the circumferential direction.

The systems and methods described herein relate to a dome of a gas turbine assembly configured to suppress pressure pulsations. The systems and methods provide a dome having an aperture configured to surround an injector assembly of a combustor. The dome having a front panel extending radially from the aperture. The systems and methods couple a first cavity to the front panel. The first cavity includes a series of ducts. A first duct of the series of ducts is configured to receive airflow into the first cavity from a compressor and a second set of ducts of the series of ducts and a third duct of the series of ducts are configured to direct airflow to the combustor from the first cavity, wherein the third duct has a larger diameter than the second set of ducts.
