Abstract
A system for selectively supplying air between separate plena of a gas turbine engine includes a gas turbine engine, a door, and a bi-metallic door actuator. The gas turbine engine comprises at least a first plenum and a second plenum, and has an opening between the first plenum and the second plenum. The is door mounted in the gas turbine engine and is movable between a closed position, in which air is prevented from flowing through the opening, and an open position, in which air may flow though the opening. The bi-metallic door actuator is coupled to the door and is configured to selectively move the door between the closed position and the open position.
