Abstract: A collapsible flap deployment system for an aircraft wing that includes a support beam pivotably connected to a carrier beam, which is connected to a wing flap. A rear spar fitting is connected to a wing rear spar by a first plurality of fasteners and a second plurality of fasteners connects the support beam to the rear spar fitting. A fuse pin connects a link to the rear spar fitting. The fuse pin is configured to shear upon the application of a first predetermined force. An impact load to the bottom of the support beam puts the link into compression applying a force to the fuse pin until the fuse pin shears releasing the link from the rear spar fitting. The impact load rotates the support beam and carrier beam causing the second plurality of fasteners to fail releasing the support beam and carrier beam from the wing rear spar.

Abstract: Embodiments provide techniques for testing a plurality of variations of a user experience, where each of the plurality of variations is distinct from other variations in the plurality of variations. For each permutation of a plurality of stratification factors that characterize users of the online site, embodiments generate a respective set of pseudorandom numbers. Additionally, user requests are assigned to variations in the plurality of variations, based on the generated sets of pseudorandom numbers. Embodiments also track user retention information relating to the user requests. At least one of the plurality of variations is rated, based on the user retention information.

The system also includes a pump configured to supply fluid to both ends of the actuator. The system also includes an energy conservation system that is configured to reduce flow from the pump to the head end of the actuator and to increase flow from a make-up fluid circuit to the head end of the actuator during an overrunning load condition. The energy conservation system also increases flow from the pump to the head end of the actuator and decreases flow from the make-up circuit to the head end of the actuator after the overrunning load condition has ceased.
