Abstract
A gas turbine engine is provided having a static structure including a flowpath wall. A fluid circuit is extended through the flowpath wall and includes a first inlet opening in fluid communication with a first cavity to receive a first flow of fluid through the fluid circuit. The static structure includes an ejector positioned at the fluid circuit, in which the ejector includes a second inlet opening in fluid communication with a second cavity to receive a second flow of fluid through the ejector and into the fluid circuit.
Claims20
A gas turbine engine, the engine comprising:
- a vane assembly comprising a flowpath wall,
- wherein a fluid circuit is extended through the flowpath wall, and
- wherein the fluid circuit defines a first inlet opening in fluid communication with a first cavity to receive a first flow of fluid through the fluid circuit, and
- wherein the vane assembly comprises an ejector positioned at the fluid circuit,
- wherein the ejector defines a second inlet opening in fluid communication with a second cavity to receive a second flow of fluid through the ejector and into the fluid circuit, the second cavity being fluidly separated from the first cavity, the second flow of fluid having a higher pressure and a higher temperature than the first flow of fluid,
- wherein the ejector comprises a nozzle positioned downstream of the second inlet opening relative to the second flow of fluid toward the fluid circuit, and
- wherein the nozzle is configured to urge the first fluid flow through the fluid circuit by ejecting the second flow of fluid from the second inlet opening through the nozzle into the fluid circuit.
A static structure for a gas turbine engine, the static structure comprising:
- a flowpath wall,
- wherein a fluid circuit is extended through the flowpath wall, and
- wherein the fluid circuit comprises a first inlet opening in fluid communication with a first cavity to receive a first flow of fluid through the fluid circuit, and
- wherein the static structure comprises an ejector positioned at the fluid circuit,
- wherein the ejector comprises a second inlet opening in fluid communication with a second cavity to receive a second flow of fluid through the ejector and into the fluid circuit, the second cavity being fluidly separated from the first cavity, the second flow of fluid having a higher pressure and a higher temperature than the first flow of fluid,
- wherein the ejector comprises a nozzle configured to urge the first flow of fluid through the fluid circuit by ejecting the second flow of fluid from the second inlet opening through the nozzle into the fluid circuit, and
- wherein the fluid circuit further comprises an outlet opening downstream of the ejector,
- wherein the outlet opening is in fluid communication with an outlet cavity, wherein the outlet cavity is fluidly separate from a gas flowpath through the gas turbine engine.
