Abstract
A turbofan engine pylon structure has a fan variable area nozzle defined by a variable area flow system between a pylon intake and a pylon exhaust to selectively adjust a bypass flow through the pylon structure. The variable area flow system changes the physical area and geometry of a pylon nozzle exit area to manipulate the bypass flow by opening and closing an additional flow area of the variable area flow system.
