ABSTRACT:
An improved gas turbine engine exhaust nozzle diverter valve is provided to selectively direct the flow of motive fluid through one of two nozzle exhaust ports and to provide improved sealing to prevent the flow of fluid through the second nozzle exhaust port. Linkage and actuator means are provided to retract a blocker door having a deformable seal attached thereto from a first seated position over the second nozzle exhaust port, and to then rotate the blocker door to a position over the first nozzle exhaust port. The method of retracting the blocker door prior to rotating it eliminates sliding friction and minimizes the potential of damage to the seal between the blocker door and the nozzle exhaust port.
