摘要： A system includes an air manifold, a fuel manifold, and a plurality of fuel injectors. At least one of the fuel injectors includes a heat exchanger portion for supplying compressed, cooled air form the heat exchanger portion to the air manifold. An air valve is operatively connected to an outlet of the air manifold for controlling release of air from the air manifold. A controller is operatively connected to the air valve, wherein the controller includes machine readable instructions configured to control the air valve to regulate flow of air through the air valve based on fuel temperatures in the fuel channel. The machine readable instructions can be configured to cause the controller to flow air through the air valve in a heat exchange mode if a fuel temperature in the fuel injectors is below a predetermined fuel temperature.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A nozzle includes a nozzle body defining a liquid circuit extending from a liquid inlet to a liquid outlet. The liquid circuit includes a plurality of spiral liquid passages spiraling radially inward relative to a spray axis. The spiral liquid passages all lie in a plane normal to the spray axis. A manifold assembly includes a plurality of such nozzles. A manifold ring is in fluid communication with the liquid inlet of each of the nozzles to deliver liquid to the nozzles. The nozzles are circumferentially spaced apart around the manifold ring.

摘要： A system for inspecting spray nozzles includes a nozzle operatively connected to a source of pressurized liquid for issuing a spray from the nozzle. The system also includes a sensor positioned to detect frequencies of resonant modes in the spray. The nozzle and sensor can each be mounted to a spray test booth. A method of inspecting a spray nozzle includes issuing a liquid from a spray nozzle as a spray and using a sensor to detect frequencies of resonant modes in the spray. The sensor can include a diaphragm and detecting frequencies can include impinging at least some of the spray on the diaphragm, and monitoring vibrations of the diaphragm.
