Abstract : This patent discloses a flap and seal assembly for an exhaust nozzle having a flap liner and seal liner which are in slidable engagement with one another. The seal liner has a facesheet, grid sheet and corrugated supporting sheet while the flap liner has a facesheet and an inner support sheet. The specific inter-relationship between the various elements of the flap and seal liner provides improved support, hot gas aspiration as well as vibratory damping which thereby allows for the use of thinner materials in the construction of the liner assembly.
