Abstract
This invention relates to a cooling air management system for a movable centerbody having articulating panels located in the two-dimensional exhaust nozzle of a jet engine so that movement of the centerbody and articulating its panels can provide thrust vectoring, variable geometry internal nozzle expansion or other flight control functions. Cooling air supplied from a fan discharge and/or ram air is fed internally of the centerbody to enhance its operation in a hostile environment while assuring sufficient pressure to effectuate cooling throughout the flight envelope of the aircraft, which during different regimes requires different cooling loads.
