  • Aircraft flap mechanism having compact large fowler motion providing multiple cruise positions
    Patent number: 8684316
    Abstract: A trailing edge flap mechanism incorporates a support beam, a flap carrier beam supporting an aerodynamic flap, a first link interconnecting a first and second rotation points and a second link interconnecting third and fourth rotation points. The support beam has a ground connection on a first fixed axis of rotation. A connecting link has a ground connection on a second fixed axis of rotation and is connected to the first link intermediate the first and second rotation points. An actuator is connected with a drive link pivotally engaged to the first link for initial forward and aft movement of a nose profile of the Fowler flap substantially parallel to the wing lower surface with extending aft movement providing a rapidly changing angle of the flap with respect to the wing upper surface.
