Abstract
A variable area, two-dimensional nozzle for exhausting a hot stream of combustion gases from a jet engine comprising upper and lower movable exhaust flaps disposed between stationary sidewalls for defining at least a portion of the exhaust path of the nozzle, each sidewall having an inner surface and outer surface. A heat exchange baffle is disposed on the outer surface of each sidewall for heating the outer surface of the sidewall to reduce the temperature differential between the inner and outer surfaces during operation of the nozzle. Ports disposed in the sidewall are provided for directing a source of hot gas into the heat exchange baffle.
