A method for controlling control surfaces. A position limit is identified for movement of a control surface based on a load limit set for the control surface and a number of vehicle current operation parameters to form an identified position limit. Responsive to receiving a command to move the control surface on a vehicle to a new position, the control surface is commanded to move to a position within the identified position limit. |

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. |

Flaps, for example leading edge flaps and/or trailing edge flaps of an aircraft wing, are driven and adjusted by respective drive units. Drive shafts of neighboring flaps are coupled to each other by a differential gear. The differential gear is thus coupled to a main drive shaft which is driven by a main drive unit. Additionally, the differential gear is coupled to a secondary drive unit. The main drive power and the secondary drive power and thus the respective flap motions are super-imposable on each other, which permits operating the flaps independently of each other or in synchronism with each other. |

A rotary vane or geared rotary actuator housing is located within the interior space of a fixed aircraft wing section, forwardly of the rear spar. The actuator movable arm extends downwardly through the wing and articulates to a push rod which is pivotally connected to a movable control surface hinge fitting. A second fixed hinge fitting is connected to the rear spar, in the interior space of the fixed wing section. When the actuator operates, the arm is rotated thereby causing movement of the push rod and rotation of the control surface hinge fitting relative to the fixed hinge fitting. This results in deflection of the control surface. Location of the actuator housing forwardly of the rear spar and well forward of the hinge enables a designer to use larger and more powerful actuators since the forward end portion of the wing has greater interior volume than the hinge area. Control and power source lines are located within the wing section for protection. Further, control and power source components can be located in an area of the wing that allows integration of these components with the power hinge portion of the actuator into one line replaceable item. |

A method and apparatus is provided, including an actuator system that may be connected to a wing frame for controlling an active element. The actuator system may include sliding elements movable along an axis parallel to the span-wise axis of the wing. The sliding elements may be connected to fixed elements and a crank element, the crank element generally comprising a beam element and a pivot element. The beam element may be offset from the pivot element so that the crank element is rotatable about the pivot element with a negative stiffness under an external force that tends to pull the sliding elements away from the fixed elements. |
