ABSTRACT:
A variable geometry exhaust nozzle is disclosed in which the follower flaps of the first, upstream ring of flaps and the second, downstream ring of flaps have a seal to seal the gap between the upstream and downstream follower flaps throughout the range of movement of the variable nozzle flaps. The sealing device has a plate extending between the downstream edge portion of an upstream follower flap and the upstream edge portion of a downstream follower flap and across the entire circumferential width of the flaps. The plate has an upstream portion pivotally connected with the downstream edge portion of the upstream follower flap and a downstream portion which has a bead pivotally contacting an inner surface of the upstream edge portion of a downstream follower flap.
