Aircraft cabin door locking system

摘要

The spacers (15,16) can be moved in the locking direction and respond to a drive (14) connected to the respective spacers, these in turn mounted on the door itself. The two spacers are positively connected to one another by hydraulics (14), pneumatics, by pressure-proof paste or a system of movable balls. Cables and pulleys can also be used for the coupling arrangement or again pushrods, with the two spacers joined by a sensor-responsive control unit. Details include the door sockets (12,13) for the two spacers which are run home by hydraulic pistons off hydraulic, pneumatic system (14). When using the ball option, these are sized to fill out the line or arranged in a closed circle. The cables if used enclose the spacers with spiral springs and in the pushrod option these are bevelled to work with bevelled surfaces on the respective spacers. Integrated sensors control stepping motors to vary the position of the spacer relative the cabin door.
