ABSTRACT:
A thrust vectoring axisymmetric vectoring exhaust nozzle having universally pivoting divergent flaps is provided with a surrounding thermal shield of overlapping outer flaps and seals generally disposed in an aftwards converging conical arrangement and having a means for changing its shape from axisymmetrical to asymmetrical. Additional thermal and cooling protection is provided by a series of ejector slots located on the divergent universally pivotal flaps and adjacent interflap seals of the nozzle to both cool and thermally shield the flaps and seals.
