The engine exhaust flow diverter is formed as a duct, extending from the exhaust section of a gas turbine powerplant, having a closed end which is contoured externally as a nozzle plug. First exit means for the flow from the powerplant extends around the duct just forwardly of the contoured plug and second exit means for the flow extends around the duct midway between the first exit means and the end of the exhaust section of the powerplant. An annular door is axially movable around the duct between an open and closed position to control the flow through the second exit opening and an annular shroud is axially movable around the duct between an open and closed position to control the flow through the second exit means. The annular shroud cooperates with the contoured nozzle plug to form a conventional nozzle. An actuating system is connected to both the annular door and annular shroud to actuate them so that when one is open the other is closed. Means insure that each door or shroud is sealed when it is in its closed position. A bellcrank lever device is connected to the annular shroud so that its movement can be varied with respect to the movement of the annular door, this is done to control the respective areas of the openings as they move between their open and closed positions to maintain a desired effective area for optimum engine operation.
