Variable area throat exhaust nozzle with vectorable sideways shifting of exhaust flow

A variable throat area nozzle comprising:

• a longitudinally extending and longitudinally split upper nozzle wall spaced upwardly and aftwardly of a longitudinally extending lower nozzle wall,
• a sideways split and aftwardly swept nozzle ramp extending between the upper and lower nozzle walls,
• the upper and lower nozzle walls and the nozzle ramp extending transversely between first and second nozzle sidewalls,
• the upper and lower nozzle walls and the nozzle ramp extending transversely between the first and second nozzle sidewalls,
• an outer nozzle wall spaced apart from the upper and lower nozzle walls, extending transversely between the first and second nozzle sidewalls,
• a nozzle flowpath defined between the upper and lower nozzle walls and the outer nozzle wall and the first and second nozzle sidewalls,
• a variable area throat extending substantially downwardly across the nozzle flowpath from the outer nozzle wall to the upper nozzle wall,
• right hand and left hand upper ramp sections of the aftwardly swept nozzle ramp connected to right hand and left hand upper nozzle wall sections respectively of the upper nozzle wall, and
• the right hand and left hand upper nozzle wall sections being upwardly and downwardly pivotally connected to an aft end of the nozzle and operable to vary a throat area of the throat.

An aircraft gas turbine engine exhaust section comprising:

• a variable throat area nozzle spaced axially downstream of an afterburner;
• the nozzle including a longitudinally extending and longitudinally split upper nozzle wall spaced upwardly and aftwardly of a longitudinally extending lower nozzle wall,
• a sideways split and aftwardly swept nozzle ramp extending between the upper and lower nozzle walls,
• the upper and lower nozzle walls and the nozzle ramp extending transversely between first and second nozzle sidewalls,
• an outer nozzle wall spaced apart from the upper and lower nozzle walls and extending transversely between the first and second nozzle sidewalls,
• a nozzle flowpath defined between the upper and lower nozzle walls and the outer nozzle wall and the first and second nozzle sidewalls,
• a variable area throat extending substantially downwardly across the nozzle flowpath from the outer nozzle wall to the upper nozzle wall,
• right hand and left hand upper ramp sections of the aftwardly swept nozzle ramp connected to right hand and left hand upper nozzle wall sections respectively of the upper nozzle wall, and
• the right hand and left hand upper nozzle wall sections being upwardly and downwardly pivotally connected along right and left handed triangular sides respectively of the right hand and left hand upper nozzle wall sections to right and left handed triangular side walls of an aft end of the nozzle and operable to vary a throat area of the throat.
