ABSTRACT:
Systems and methods for providing differential motion to wing high lift devices are disclosed. A system in accordance with one embodiment of the invention includes a wing having a leading edge, a trailing edge, a first deployable lift device with a first spanwise location, and a second deployable lift device with a second spanwise location different than the first. The wing system can further include a drive system having a drive link operatively coupleable to both the first and second deployable lift devices, and a control system operatively coupled to the drive system. The control system can have a first configuration for which the drive link is operatively coupled to the first and second deployable lift devices, and activation of at least a portion of the drive link moves the first and second deployable lift devices together. In a second configuration, the drive link is operatively coupled to at least the first deployable lift device and operatively decoupled from the second deployable lift device, so that actuation of at least a portion of the drive link moves the first deployable lift device relative to the second deployable lift device.
