| 摘要 |
The objective of the invention is to replace the rope bar of the door evacuation slide with individual connections. According to a preferred embodiment, the mechanism for arming/disarming an aircraft door evacuation slide (1, 15, 16) includes two releasable connectors (21) disposed to either side of the base of the door and each includes two half connectors (21s, 21i), a so-called upper half connector (21s, 41, 4a, 42) rigidly connected to the door (1) and having an attachment device (33) for attachment to the slide, and a so-called lower half connector (21i) fixed to the cabin floor (6). Each upper half connector (21s) includes a movable inner part controlled by a ring (43) and housed in the corresponding lower half-connector (21i). The mechanism can also include an electric motor coupled to two rods (31), each rod (31) being capable of rotating the control ring (43) of each upper half connector (21s) between two angular positions: an armed position and a disarmed position. |

1. A method for arming and/or disarming an evacuation slide (3) of an aircraft door (1) connected to a cabin floor (6) of an aircraft comprising;
an arming mode (ARM) for lowering the aircraft door (1) into a closed position to engage parts (21s, 21i; 22s, 22i) forming at least two releasable connections (21, 22) coaxial with an axis perpendicular to the cabin floor (6); the parts (21s, 21i; 22s, 22i) of each connection (21, 22) being rigidly connected to the door (1) and to the cabin floor (6), respectively, locking the connections (21, 22) by driving using a locking motion (T1, R1) triggered by a control (51) of an energy source (23); wherein said locking motion includes driving in rotation (R2) about the axis of each connection (21, 22) induced by driving in translation (T2) by coupling with the energy source (23) until a configuration is reached locking the connections (21, 22); wherein in the event of an emergency evacuation, unfurling and inflating the evacuation slide (3) attached only to each connection (21, 22), and disarming mode (DISARM) unlocking said connections by a mechanically driven reverse motion (T2, R2) and then raising the door (1) to decouple the connections (21, 22) before opening the door. |
