  • Nozzles for gas turbine engines
    Patent number: 4049199
    Abstract: A variable area convergent/divergent iris nozzle for a gas turbine engine has a plurality of interdigitated master and slave petals. Each master petal has a pair of axially spaced rollers which run on guide tracks mounted on the engine jet pipe. A pivotable link connects the upstream end of each master petal to a unison ring which is axially movable to translate the petals thereby varying the area of the nozzle.
