Abstract
A system includes a turbine exhaust section having an exhaust flow path, an inner exhaust wall radially disposed along the exhaust flow path, an outer exhaust wall disposed radially outward of the inner exhaust wall and along the exhaust flow path, and a flow control vane extending between a first end and a second end. The first and second ends are circumferentially offset from one another. The flow control vane is configured to move between a retracted position along the outer exhaust wall and an extended position extending from the outer exhaust wall toward the inner exhaust wall. The second end is disposed radially inward from the first end while the flow control vane is disposed in the extended position.
