Exhaust nozzle flap seal arrangement

摘要

A variable area exhaust nozzle is provided with seals between adjacent flaps to minimize flow loss therebetween when the flaps are modulated between minimum and maximum nozzle area positions. The overlapping seals is linked to the adjacent flaps by means of a bellcrank which operates to maintain the seal in a centered position between the flaps. A circumferential track is provided on the flaps to stabilize the seal in the axial direction.
