In an exemplary variable area nozzle, a fixed duct section has an inlet and an outlet oriented approximately perpendicular to the inlet. A controllable nozzle member is disposed adjacent the outlet of the fixed duct section. The controllable nozzle member has an area that is adjustable to maintain a substantially constant nozzle pressure ratio. The controllable nozzle member may include first and second flap doors hinged and pivotable in opposite directions between an open position and a closed position and that also may be hinged and pivotable in a same...


What is claimed is: 1. A variable area nozzle comprising: a fixed duct section having an inlet and an outlet that is oriented substantially perpendicular to the inlet; and a controllable nozzle member disposed adjacent the outlet of the fixed duct section, the controllable nozzle member having a first flap door and a second flap door, wherein the first flap door and the second flap door present a smoothly contoured inner surface to vary a nozzle throat height and a nozzle pressure of the variable area nozzle based on a deployment angle of the first flap...
