Abstract
A thrust vectoring axisymmetric convergent divergent variable exhaust nozzle is provided with a universally pivoting joint between the divergent and convergent flaps and actuating the linkage mechanisms for changing the divergent nozzle section from axisymmetrical to asymmetrical by pivoting the divergent flaps in the radial and tangential directions with respect to the axisymmetric nozzle centerline in a controlled manner.

A means for vectoring the thrust of an axisymmetric convergent/divergent nozzle comprising:
- a divergent nozzle section having a longitudinal axis, said divergent nozzle section comprising a plurality of divergent flaps and a means for changing said divergent nozzle section from axisymmetrical about said longitudinal axis to asymmetrical.
A means for vectoring the thrust of an axisymmetric convergent/divergent nozzle as in claim wherein said actuating means further comprises a means for axially translating said actuating ring.
A means for vectoring the thrust of an axisymmetric convergent/divergent nozzle as in claim wherein said means for tilting said actuating ring and said means for axially translating said actuating ring comprises a plurality of linear actuators fixed relative to the nozzle casing and operably connected to said actuating ring.
A vectorable axisymmetric convergent/divergent nozzle comprising:
- in serial flow relationship and defining a flow path;
- a fixed nozzle casing,
- a convergent nozzle section,
- a throat, and
- a divergent nozzle section having a longitudinal axis wherein said divergent nozzle section comprises a plurality of divergent flaps and a divergent flap control means for changing the flow path in said divergent nozzle section from axisymmetrical about said longitudinal axis to asymmetrical.
