    摘要: Described herein is a system that includes an actuator with a movable input, a first summing mechanism with an input, a first output, and a second output. The input of the first summing mechanism is movably driven by the movable input of the actuator and the first output of the first summing mechanism is movably coupled to a first actuatable element. The system also includes an end mechanism with an input and a first output. The input of the end mechanism is movably driven by the second output and the first output of the end mechanism is movably coupled to a second actuatable element. The system further includes a sensor that senses a position of the rotational input of the actuator. A status of the first and second actuatable elements is based on a sensed position of the movable input of the actuator.

    摘要: An actuation system for controlling flight control members of a vehicle. Each flight control member is controlled by two or more linear hydraulic actuators. Synchronization members extend between the hydraulic actuators on the same flight control members to synchronize the movements of the hydraulic actuators for consistent movement across the length of the flight control members. Brakes can maintain the positions of the synchronization members and thus the flight control members. Motors can provide for moving the synchronization members to control the positioning of the hydraulic actuators and flight control members.

    摘要: A folding wing tip system of an aircraft includes a latch pin actuator having a primary mechanical lock and a secondary hydraulic lock. The mechanical lock may include a lock cam movable between a lock position, in which the lock cam engages the latch pin, and an unlock position, in which the lock cam is disengaged from the latch pin, and a first lock actuator mechanically coupled to the lock cam and configured to provide a bias force pushing the lock cam toward the lock position. The hydraulic lock may be disposed in an unlatching hydraulic line and has an initial state, in which fluid flow through the unlatching hydraulic line is blocked thereby to hold the latch pin in the latched position, and an open state, in which fluid flow through the unlatching hydraulic line is permitted thereby to permit retraction of the latch pin to the unlatched position.
