摘要
A turbofan engine (10) includes a variable area fan nozzle (42) which effectively changes the physical area and geometry within a fan bypass flow path (40) to manipulate the pressure ratio of the bypass flow with a multitude of bladders (52A...52D) circumferentially located about a core cowl (12).A method of varying such a fan nozzle exit area with a bladder system is also disclosed.
