0916A PATENT 13DV-9687 ABSTRACT An interflap segmented seal is provided for use between adjacent flaps of an axisymmetric vectorable exhaust nozzle in order to minimize flow loss therebetween when the flaps are pivoted through different angles in order to turn the exhaust flow and vector the thrust. The overlapping seal segments are mounted to a backbone having an elliptical cross-section by a flange with a lobed hole in it through which the backbone passes. Spacers between the flanges axially position the individual segments from each other. Variable movement between adjacent flaps produces different angles between the sealing edges of the flaps which are often skewed with respect to each other and the flexibility afforded by the seals of the present invention allows the seals to minimize the leakage between the flaps and the seals.
