    • A linear actuator comprises a drive unit housing (10) with a drive unit (7, 8) arranged therein, a driveshaft (1), hollow on the inside, driven by the drive unit (7, 8), and a profile tube (2) non-rotatably and longitudinally movably connected on the outside to the driveshaft (1). A threaded hollow spindle (3) with an outside thread is arranged between the driveshaft (1) and the profile tube (2) and fixedly connected to the drive unit housing (10). A hollow-spindle nut (4) is fixedly connected to the profile tube (2) at a first end of the profile tube (2) and cooperates with the outside thread of the threaded hollow spindle (3). A spindle nut (6) is fixedly connected to the profile tube (2) at a second end thereof. A threaded spindle (5) is arranged in the interior of the driveshaft (1) and cooperates with a thread of the spindle nut (6).

    • This disclosure relates to a landing gear system that includes a landing gear strut rotatable between stowed and deployed positions. A lock-stay is connected to the landing gear strut and is movable between locked and unlocked conditions. An unlock actuator (24) is connected to the lock-stay and includes first (44) and second (48) members movable relative to one another. The first member is movable between first and second positions that correspond to the locked and unlocked conditions. A controller is in communication with the unlock actuator and is configured to command the unlock actuator between the first and second positions in response to an input. The second member is permitted to free-drive relative to the first member between the stowed and deployed positions with the lock-stay in the unlocked condition.
    • 本公开涉及一种起落架系统,其包括可在收起位置和展开位置之间旋转的起落架支柱。 锁定支架连接到起落架支柱,并且可在锁定和解锁状态之间移动。 解锁致动器(24)连接到锁定支架,并且包括可相对于彼此移动的第一(44)和第二(48)构件。 第一构件可在对应于锁定和解锁状态的第一和第二位置之间移动。 控制器与解锁致动器通信并且被配置为响应于输入而在第一和第二位置之间命令解锁致动器。 允许第二构件在收起位置和展开位置之间相对于第一构件自由驱动,在锁定状态下进行锁定。
