Abstract
This invention relates to sealing means for a movable centerbody having collapsible panels located in the two-dimensional exhaust nozzle of a jet engine so that movement of the centerbody and collapsing its walls serves to provide thrust vectoring, variable geometry and internal nozzle expansion. Cooling air supplied internally of said centerbody is utilized to pressurize the seal to assure that the jet exhaust does not ingress into the centerbody cavity or cooling air does not indiscriminately egress therefrom.
