Abstract
A variable area exhaust nozzle 26 is provided. The variable area exhaust nozzle 26 includes a nozzle opening 30 and a plurality of nozzle flaps 38 and 40. The nozzle opening 30 has a cylindrical area and a circumference. The plurality of nozzle flaps 38 and 40 are supported about the circumference of the nozzle opening 30. The nozzle flaps 38 and 40 have an axis of rotation 52. The nozzle flaps 38 and 40 are positioned to rotate into the nozzle opening 30 to decrease the cylindrical area of the nozzle opening 30 and to rotate out of the nozzle opening 30 to increase the cylindrical area of the nozzle opening 30. The nozzle flaps 38 and 40 rotate to vary the cylindrical area of the nozzle opening 30 and to reduce the forces required to rotate the nozzle flaps 38 and 40.
