For example, the systems disclosed herein can, in some embodiments, reduce or eliminate the need for latch fittings mounted to the fuselage door surround and consequently reduce the amount of adjustment/rigging of doors during manufacturing of aircraft. A method for unlocking and unlatching an aircraft door, the method comprising:20.

The door you mentioned is called a Plug Door.. On some aircraft the plug door opens partially inward, and through a complex hinge design can be tilted to fit through the fuselage opening, or the door may have locking hinged panels at the top and bottom edges that can make it smaller than the opening, so that it may be swung outward. The mechanism prevents a hijacker from entering the cockpit compartment and allows the door to open rapidly when a catastrophic decompression event occurs in the airplane.


Existing latching mechanisms include fittings that are mounted to the fuselage and that cooperate with mechanical elements on the door to achieve latching of the door. Non-plug doors rely on the strength of the locking mechanism to keep the door shut. The latch lock mechanism (20) of this invention includes a latch shaft (38) that is mounted to the door (22) by a set of follower bearings (98) that are axially offset from the shaft. The method as defined in claim 27, comprising using a closing movement of a vent flap of the aircraft door to drive the configuration change of the lock.

Improvement is desirable.In one aspect, the disclosure describes a system for latching and locking an aircraft door.

<> The system comprises a latch and a lock.

In some embodiments, flight loads can be transferred to the fuselage via a hinge of the door instead of such other latch fittings mounted to the fuselage. endobj
The fittings mounted to the fuselage must be properly adjusted (i.e., rigged) during manufacturing of each aircraft and such adjustments can be time consuming and expensive. ?�1\�~8��ͤ�����W��V��'{yo|%E�����$�,��s(6�Ov!�����7q�������sw&��г�4_��M or���5���U)�l�I|W��u".��ɢ|�����~xvv5 ���c����J'��ĉ�� x��}�r�H��#��av�ޖ٨B����$�xƖ��ܽ'f�DB"�0�@˚/����K�B� �4��K��̬������.��?������p~�E�<=���#���8�����4��'?F΃G*�C���_VZK���Ϳ���?x&�ޞњZ6S�h}�J9�� ������Bya4�|�_Υ�O ��O�m�Ӎ�ͬ���}/ �r"���||e��� �NXc�{��1pC��C��?

What door mechanisms exist in commercial aircraft, ... Cranking the handle opens the locking mechanism, then you manhandle the door the rest of the way. Aircraft doors also include a lock that prevents the latching elements from unexpectedly becoming disengaged. The latch may permit rotation of the lift shaft when the latch is in the unlatched configuration.The lock may interfere with a rotation of a latch shaft of the latch when the lock is in the locked configuration. An aircraft emergency exit door (10) with opening mechanisms integrated by a grouping of the mechanisms into a door beam (3) located on a given side of a window (16) of standard dimensions.In the beam, an inner handle (1) is mounted on a main shaft (102) connected with a locking shaft (8A) on which there is mounted, against return springs (83), a door blocking/locking mechanism (8) … 1 0 obj Valentini, L.
