Patent number: 9777671Abstract: A variable area fan nozzle assembly for a turbofan engine includes a nacelle having an aft edge and a translating thrust reverser sleeve with a trailing edge. The thrust reverser sleeve is movably disposed aft of the nacelle's aft edge and is movable between a forward position and an aft position. A translating fan nozzle having a forward edge is movably disposed behind the trailing edge, and is movable between a stowed position and a deployed position. An upstream bypass flow exit is defined between the trailing edge and the forward edge when the fan nozzle is in the deployed position. An extendable actuation system is configured to move the fan nozzle between the stowed position and the deployed position.Type: GrantFiled: February 18, 2013Date of Patent: October 3, 2017Assignee: ROHR, INC.Inventors: Jihad I. Ramlaoui, Geoffrey Pinto, Daniel Shetzer, Daniel M. Amkraut, Andrew Robert Hawksworth, John Harvey, Alan K. Evans, Vikram Chandarana, Roger Moorhouse
