Zusammenfassung:	An axial divergent section slot nozzle (10) for an engine is provided. The nozzle has a plurality of spaced apart divergent flaps (12), at least one device for moving the divergent flaps (12) to change a cross sectional area of the nozzle in a throat region, and a bridge member (20) positioned intermediate adjacent ones of the flaps (12). The bridge member (20) includes a bridge bracket (216) and a sealing element (204) joined to the bridge bracket (216). The sealing element (204) has an upper surface (226). The bridge bracket (216) has a lower surface (222,224) which diverges from the upper surface (226) of the sealing element (204). In a preferred embodiment of the present invention, the bridge bracket (216) has a shape which allows variable slot size depending on nozzle throat jet area.
