ABSTRACT:
An air-cooled, variable-throat, convergent-divergent nozzle for a turbojet engine. Active cooling constituent structures of the nozzle include: passages, for flow of cooling air, integral to, and within, convergent and divergent flaps and seal members; finned sections in nozzle components which are provided air from the passages; air exit slots on the convergent flaps; a hinged connection at each convergent flap-to-divergent flap (and divergent seal member) interconnection; staggered air outlet openings in each divergent flap; and, a tubular air feed system to provide cooling air from each divergent flap to an adjacent cooperating divergent seal member. Passive cooling is accomplished: by seal members overlapping adjacent side edges of convergent and divergent flaps, preventing leaking of cooling air and hot gas through the side edges; and, by a sealing hinged connection at each convergent flap-to-divergent flap (and divergent seal member) interconnection.
