Abstract: A method of joining includes applying braze to a braze reservoir in a first component. A second component is engaged to the first component, wherein a joint location is defined between the first and second components. A wicking structure provides flow communication from the braze reservoir to the joint location. The method also includes joining the first and second components together at the joint location by applying heat to the braze to flow the braze from the reservoir through the wicking structure to the joint location to form a braze joint at the joint location.

Abstract: A method of manufacturing includes depositing a predetermined amount of braze material directly to a joint location of a first component and joining the first component to a second component at the braze joint location. The method also optionally includes depositing a predetermined amount of braze material directly to a joint location of the second component. Machining down the braze material on each of the first and second components can be used to provide a preformed braze joint.

Abstract: A nozzle assembly includes a nozzle body defining an inlet and an opposed spray outlet for producing a spray of fluid supplied at the inlet. The nozzle body includes a radially outward extending retainer feature. An adapter having an adapter bore therethrough is provided for supplying fluid to the inlet of the nozzle body. The nozzle body is engaged within the bore of the adapter. A retainer radially outward of the adapter and nozzle body includes a retainer feature engaged to the retainer feature of the nozzle body to hold the nozzle body and adapter body together. A sleeve is engaged to the retainer radially outward thereof to prevent disengagement of the retainer features of the nozzle body and retainer. The sleeve and retainer are configured for relative movement for releasing the retainer features of the nozzle body and retainer for removal of the nozzle body from the adapter.

Abstract: An injection system includes an inner nozzle body defining a first air path along a longitudinal axis. The first air path defines a converging-diverging section between an upstream portion of the first air path and an outlet orifice of the first air path. A main orifice is defined at a narrowest portion of the converging-diverging section. A fuel circuit wall is outboard of the inner nozzle body. A fuel path is defined between the fuel circuit wall and the inner nozzle body. An outer nozzle body outboard of the fuel circuit wall has a second air path defined through the inner nozzle body for communication of air from the outer nozzle body into the first air path, wherein the second air path meets the first air path at a second orifice in the first air path downstream of the main orifice of the inner nozzle body.

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: An embodiment of an ignition system for a gas turbine engine includes a high pressure engine case, a torch ignitor disposed at least partially within the high pressure engine case, the torch ignitor having a combustion chamber oriented about a torch axis, the combustion chamber having axially upstream and downstream ends defining a flow direction through the combustion chamber, along the axis. The ignition system also includes an access hatch configured to allow access through a high pressure engine case to the cap and to seal against the high pressure engine case when not accessing the cap. An embodiment of a method includes removing a hatch from a high pressure engine case to open a hatch opening, performing maintenance on a torch ignitor that is inside the high pressure engine case by accessing the torch ignitor through the hatch opening, replacing the hatch to close the hatch opening after completion of maintenance on the torch ignitor.
