Abstract
A method for adjusting a throat area of a jet aircraft exhaust nozzle assembly includes positioning a lower structure within a substantially rectangular nozzle assembly, coupling a ramp flap to the lower structure, and coupling an outer flap to the nozzle assembly such that movement of at least one of the ramp flap and the outer flap adjusts the throat area of the nozzle assembly.
Claims19
A method for assembling an exhaust nozzle, said method comprising:
- positioning a lower structure within a substantially rectangular nozzle lower assembly, said nozzle having an exit area and a throat area;
- rotatably coupling a single ramp flap within said nozzle to the lower structure;
- rotatably coupling a single outer flap to the nozzle assembly such that movement of the ramp flap and the outer flap adjusts the throat area of the nozzle assembly;
- said outer flap comprising an external surface of said nozzle.

A exhaust nozzle assembly comprising:
- an exit area and a throat area;
- a lower structure positioned within a substantially rectangular nozzle lower assembly;
- a single ramp flap rotatably coupled within said nozzle to said lower structure;
- and
- a single outer flap rotatably coupled to said nozzle assembly, at least one of said ramp flap and said outer flap configured to adjust a throat area of said nozzle assembly;
