  • Publication number: 20260062130
    Abstract: An aircraft door architecture having: a door (1); an ejector (3); an inflatable evacuation device (4); a supercapacitor as an emergency energy source (6) that is connected to the retaining bar actuator (5), a control unit (9) having the two following operating states: a nominal operating state in which the inflatable evacuation device (4) is kept in its retracted position and the emergency energy source is deactivated; an emergency operating state in which the emergency energy source (6) activates the actuation device of the ejector (3) in an emergency opening mode of the door (1), and activates the inflation device of the inflatable evacuation device (4) in an emergency inflation mode.

  • Patent number: 12552516
    Abstract: An assembly of a vehicle door (3) and of a panel (1) surrounding the door in which an edge protector (4) extends along a skin (3a) of the vehicle door facing the skin (1a) of the panel and has a portion disposed between the skins (1a, 3a) following when in a nominal position the geometric alignment of their exterior faces. This edge protector (4) has in a median portion (4b) a profile that is adapted to evolve and is made of an elastic material so that it has sufficient flexibility in a direction parallel to the distance between the skins (1a, 3a) and a transverse stiffness in the internal-external direction and its contact with the skin (1a) of the panel does not block opening of the door or damage the skins (1a, 3a).

  • Patent number: 12338667
    Abstract: Aircraft door designed to assume a first configuration and a second configuration, having a bistable mechanism biasing the aircraft door towards either the first or second configuration, the bistable mechanism including: a first yoke having a base attached to the first member and a first pivot rotatably mounted on the base; a second yoke having: a base attached to the first member; a lever a first end of which is mounted so as to pivot on the base; a second pivot mounted so as to rotate on the second end of the lever; a coupling device for coupling the lever to the second member of the door; an arch which can be elastically deformed by bending and a first end of which is attached to the first pivot and a second end attached to the second pivot.

  • Publication number: 20230011589
    Abstract: Aircraft door (1) including a safety latch (7) having a first locking element (8) and a complementary second locking element (9) which is movable; a link (11) having at least one electroactive polymer portion (13) and adapted to take up: a lock position in which the electroactive polymer portion (13) is supplied with power and the movable second locking element (9) is engaged with the first locking element (8); and an unlock position in which the electroactive polymer portion (13) is not supplied with power and the movable second locking element (9) is kept away from the first locking element (8); a control unit (16) having a power supply (26) for the electroactive polymer portion (13).
