Abstract
Cooling ambient air is induced through openings in the upstream portion of each divergent flap at intermediate throat areas where the nozzle pressure is below ambient pressure. A barometric damper in these openings prevents outflow of hot gases when operating near the minimum throat area and maximum throat area since the internal pressure is above ambient pressure during such operation.
