A vane structure includes a baffle movably mounted within an aperture, the baffle movable to control a cooling flow between a first cooling cavity and a second cooling cavity.
Claims20
A vane structure for a gas turbine engine comprising:
- an airfoil section which defines an aperture, a first cooling cavity in communication with said aperture and a second cooling cavity in communication with said aperture;
- and
- a baffle movably mounted within said aperture, said baffle movable to control a cooling flow between said first cooling cavity and said second cooling cavity.
A vane structure for a gas turbine engine comprising:
- an airfoil section which defines an aperture, said aperture circular in cross-section;
- and
- a baffle movably mounted within said aperture, said baffle circular in cross-section.
A method of communicating a cooling airflow comprising:
- rotating a baffle within an airfoil section of a turbine vane.
