Problems solved by technology

The disadvantage here is that the electromechanical operating device can no longer be returned to the initial state by simply disconnecting the power supply, or can not be reset / restarted in any state

Embodiment Construction

[0029] figure 1 A locking system 10 of an aircraft, here a locking system for landing gear of an aircraft, in particular an aircraft, is shown in a schematic front view. Such a locking system 10 can also be used in a corresponding variant for locking a door locking device of an aircraft. The locking system 10 is also referred to as an uplock.

[0030] For reasons of redundancy, two drives 20 and 30 are provided, by means of which the locking system 10 can be actuated.

[0031] An electric drive 20 is therefore provided as the first drive, which can be a brush motor 20 for example. At the torque output, the electric motor 20 is associated, for example, with a planetary gear 40 and transmits the output torque to a shaft with a cam disk 60 , for example via a worm gear 50 . By means of usually for action according to figure 1 The cam plate 60 rotated counterclockwise in the view of , can move the actuating lever 70 such that the hook 80 moves from a first position, which is a...

Abstract

The system (10) has a hook (80) movable to two positions, and a control device (100) for ensuring reaching of a defined end position of the hook and / or for monitoring the locking system. The hook is engaged in an actuating lever (70) such that the hook locks the locking system in one of the positions. The hook is released from the actuating lever such that the hook unlocks the locking system in the other position. An eccentric unit i.e. cam disk, moves the hook to the positions, and the control device monitors the eccentric unit.

Description

technical field [0001] The invention relates to a locking system, in particular for an aircraft, and to a power distribution device for a locking system. Background technique [0002] Contemporary aircraft today have retractable landing gear that is mostly hydraulic. In order to ensure the flight performance especially in high-speed flight, it is necessary that the landing gear system of the aircraft can be reliably retracted during flight, kept in place and can also be reliably extended as required, for example, during landing. [0003] Hitherto, secure holding in position has been achieved by locking systems which are mechanically coupled to the aircraft structure and form a form-fit connection with the undercarriage system in the retracted state of the undercarriage system. [0004] Only during an externally activated hook opening movement is the undercarriage system released in a form-fitting manner and deployed either hydraulically or by gravity. Because of relatively...
