Abstract: A torch igniter for a combustor of a gas turbine engine includes an igniter body and an igniter head. The igniter body is disposed within a high-pressure case of a gas turbine engine and extends primarily along a first axis, and includes an annular wall and an outlet wall. The annular wall surrounds the first axis and defines a radial extent of a combustion chamber therewithin. The outlet wall is disposed at a downstream end of the annular wall, defines a downstream extent of the combustion chamber, and includes an outlet fluidly communicating between the combustion chamber and an interior of the combustor. The igniter head is removably attached to the igniter body at an upstream end of the annular wall, wherein the igniter head defines an upstream extent of the combustion chamber, and includes an ignition source and a fuel injector.

Abstract: An embodiment of a system for measuring fuel ignition within a torch igniter for a combustor in a gas turbine engine includes a housing surrounding and defining a combustion chamber, a first glow plug received through the housing, and control circuitry. An innermost end of the first glow plug extends into the combustion chamber while an outermost end opposite the innermost end extends away from the combustion chamber. The control circuitry is connected to the outermost end of the glow plug and is configured to measure a temperature of the innermost end of the glow plug based on electrical resistance of the glow plug. The control circuitry is further configured to determine an operational parameter of the torch igniter based on the temperature.

Abstract: An embodiment of a torch igniter for a combustor of a gas turbine engine comprises a combustion chamber oriented about an axis, a cap defining an axially upstream end of the combustion chamber and oriented about the axis, a tip defining an axially downstream end of the combustion chamber, a structural wall coaxial with and surrounding the igniter wall, an outlet passage defined by the igniter wall within the tip, and a cooling system. The cooling system comprises an air inlet formed within the structural wall, a first flow path disposed between the structural wall and the igniter wall, and an aperture extending through the igniter wall transverse to the flow direction. The aperture directly fluidly connects the first flow path to the combustion chamber.

Abstract: A system includes a combustor. The combustor has a combustor wall with a combustor dome at an upstream end of the combustor wall, and an outlet at a downstream end of the combustor wall opposite the upstream end. The combustor wall includes an inner wall portion and an outer wall portion defining an interior of the combustor therebetween. Each of the inner wall portion and outer wall portion extends from the combustor dome to the downstream end of the combustor wall. The combustor wall includes an air cooling passage embedded inside at least one of the inner wall portion and the outer wall portion. The air cooling passage extends from the upstream end of the combustor wall to the downstream end of the combustor wall.

Abstract: A method includes forming a fluid conduit inside a heat shield in an additive manufacturing process, wherein a fluid nozzle is defined at a downstream end of the fluid conduit, and wherein the heat shield is formed about the fluid nozzle. The method includes removing powder from an interior passage of the fluid conduit and fluid nozzle and from an insulation gap defined between the heat shield and the fluid conduit and fluid nozzle. The method includes separating the heat shield, fluid conduit, and fluid nozzle from the build platform. The method includes shifting the fluid conduit and fluid nozzle to a shifted position relative to the heat shield, and securing the fluid conduit and fluid nozzle to the heat shield in the shifted position.

Abstract: A method includes beginning an additively manufactured build by depositing initial layers of the build on a build plate, and additively manufacturing a temperature control channel as part of the build in progress. The method also includes controlling temperature in the temperature control channel while continuing to additively manufacture the build to provide temperature control for the build in progress. The method also includes completing additive manufacture of the build. The method can include removing the temperature control channel from the build after completion of the build.

Abstract: A fluid distributor includes a distributor body defining a plurality of fluid distributor passages therethrough. Each of the fluid distributor passages winds in swirl direction about a swirl axis. The swirl direction defines a swirl angle of at least 60 degrees relative to the swirl axis. Each of the fluid distributor passages defines a floor and opposed ceiling, and an opposed pair of sidewalls. At least one of the floor and/or the ceiling is vaulted to define a surface that is angled less than 60 degrees relative to the swirl axis.

Abstract: A swirler includes a swirler body defining a diverging upstream surface defining a longitudinal axis and a plurality of swirl vanes extending from the diverging upstream surface. The swirl vanes are angled to impart swirl around the longitudinal axis on a fluid flow over the diverging upstream surface. An airblast injector includes a swirler as described above, and a nozzle body defining an air passage therethrough along the longitudinal axis with a diverging outlet. The swirler is operatively associated with a diverging outlet of the nozzle body. An annular swirler outlet area can be defined between downstream ends of the swirler and diverging outlet of the air passage. A throat area can be defined in the air passage upstream of the diverging outlet thereof. The swirler outlet area can be greater than the throat area.
