摘要： An air shroud for a nozzle includes an air shroud body defining an inlet and an outlet in fluid communication with one another to allow an outer airflow to issue therefrom, the air shroud body defining a downstream surface. A plurality of air wipe channels are defined within the air shroud body, wherein each of the plurality of air wipe channels is in fluid communication with at least one of a plurality of air wipe outlets and air wipe inlets. Each air wipe outlet is defined in the downstream surface of the air shroud body such that air can flow through each air wipe outlet and wipe the downstream surface of the air shroud body.

摘要： A fuel injector for a gas turbine engine includes a nozzle tip assembly having a substantially monolithically formed nozzle body. The nozzle body has an annular outlet chamber for issuing a spray from the nozzle tip. A feed channel is in fluid communication with the outlet chamber through a feed passage. A heat shield void substantially surrounds the feed channel(s).

摘要： An air shroud for a nozzle includes an air shroud body defining an inlet and an outlet in fluid communication with one another to allow an outer airflow to issue therefrom. The air shroud also includes an air wipe disposed outboard of the air shroud body including a web defining a plurality of air wipe outlets in fluid communication with a downstream surface of the air shroud body such that air can flow through the air wipe outlets and wipe the downstream surface of the air shroud body. The air wipe can be integral with the air shroud body.
