Abstract: A flap support mechanism includes a carrier beam on which a flap is mounted. The carrier beam is rotatably mounted to a flap support for rotation relative to a wing. A crankshaft assembly is rotatable about an axis and has a crankshaft eccentrically extending between an inboard cylindrical support and an outboard cylindrical support. A coupler link is rotatably engaged to the crankshaft and pivotally connected to the carrier beam. Rotation of the crankshaft from a first eccentric position to a second eccentric position translates the coupler link between a retracted position and a deployed position.

Abstract: A deployable vortex generator attached to a lifting surface includes a vane moveable relative to the lifting surface. The vane moves from a deployed position to a retracted position in response to a change in ambient conditions. In the deployed position, the vane acts on the air flow to create vortices. In the retracted position, the vane is closely aligned with the free stream velocity.
Abstract translation: 附接到提升表面的可展开的涡流发生器包括相对于提升表面可移动的叶片。 响应于环境条件的变化，叶片从展开位置移动到缩回位置。 在展开位置，叶片作用在空气流上以产生涡流。 在缩回位置，叶片与自由流速度紧密对齐。

Abstract: An actuation mechanism, a flap mechanism, and an aircraft. The actuation mechanism includes drive links and drive mechanisms connected to opposite ends of the flap that move the flap to various positions. The drive mechanisms are actuated by torque tubes connected to a drive motor via a differential. The differential distributes torque to the torque tubes. In the event of abnormal operation of one of the drive links or drive mechanisms, the differential limits torque to the remaining drive link and drive mechanism such that the flap does not deploy or retract in a skewed manner.
