Abstract
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.
Claims14
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, a second cooling cavity in communication with said aperture and a third cooling cavity in communication with said aperture;
- and
- a rotatable baffle mounted within said aperture and through an outer vane platform segment, said baffle rotatably movable to selectively vary a cooling flow from said aperture to each of said first cooling cavity, said second cooling cavity and said third cooling cavity,
- where said rotatable baffle terminates in an inner vane platform segment.
1 more element
A method of communicating a cooling airflow comprising:
- rotating a baffle within an aperture of an airfoil section of a turbine vane to control a cooling flow between a first cooling cavity in communication with said aperture, a second cooling cavity in communication with said aperture and a third cooling cavity in communication with said aperture,
- where said baffle is movably mounted through the airfoil section and an outer vane platform segment, and
- where said baffle terminates in an inner vane platform segment.
