Abstract
An air distribution system for cooling a component in a heated gas environment may be provided, where the air distribution system includes a wall and a plate. The wall includes an inner surface, an outer surface configured to be exposed to the heated gas environment, and a protrusion extending from the inner surface of the wall. The plate is fixedly coupled to the protrusion and is space apart from the inner surface of the wall. The plate includes an outer edge. A passage is defined between the plate and the inner surface of the wall. The inlet of the passage is defined by the outer edge of the plate.
Claims20
An air distribution system for cooling a component in a heated gas environment of a gas turbine engine, comprising:
- a wall comprising an inner surface, an outer surface configured to be exposed to the heated gas environment, and a protrusion extending from the inner surface of the wall;
- and
- a plate spaced apart from the inner surface of the wall, the plate comprising an outer edge, the plate fixedly coupled to the protrusion, wherein a passage is defined between the plate and the inner surface of the wall, and wherein an inlet of the passage is defined by the outer edge of the plate.
A turbine vane comprising:
- a wall comprising an inner surface, an outer surface, and a protrusion extending from the inner surface of the wall;
- a plate spaced apart from the inner surface of the wall, the plate comprising an outer edge, wherein the plate is fixedly coupled to the protrusion;
- and
- an airfoil extending outwardly from the outer surface of the wall, wherein a passage is defined between the plate and the inner surface of the wall, and wherein an inlet of the passage is defined by the outer edge of the plate.
A method of cooling a component of a turbine vane comprising:
- supplying cooling air to a passage, wherein the passage is defined by a wall of the turbine vane and a plate spaced apart from the wall, wherein the plate is fixedly coupled to a protrusion which extends between the plate and the wall, and wherein an inlet of the passage is defined by an outer edge of the plate;
- and
- releasing the cooling air from the passage through an outlet of the passage.
