During opening and closing the door moves by means of a hinge mechanism with two mutually parallel rotational axes and an intermediate hinge part one of the rotational axis being connected to the door and the other being connected to the door case.
Aircraft door hinge mechanism.
A plug door is a door designed to seal itself by taking advantage of pressure difference on its two sides and is typically used on aircraft with cabin pressurization the higher pressure on one side forces the usually wedge shaped door into its socket making a good seal and preventing it from being opened until the pressure is released non plug doors rely on the strength of the locking.
The other end of the goose neck member is pivotally connected to the door.
The electrical door is also lighter and less costly than traditional mechanical doors.
Finally its architecture makes it highly customizable to answer any aircraft needs.
A passenger door 34 is connected to an aircraft fuselage 12 by a hinge mechanism 10 having an elongated goose neck hinge member 22.
The other end of the goose neck member is pivotally connected to the door 34.
A hinge assembly 14 for attaching a translating motion type aircraft door 10 to an aircraft fuselage 12 is disclosed.
The main components of the next generation equipped door are.
The door you mentioned is called a plug door.
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.
One end of the hinge member is pivotally connected to an idler crank arm 18 that is pivotally connected to the fuselage.
Aircraft door of the type which during the flight is pressed all around against the door case under influence of the cabin pressure.
The mechanism eliminates hinge cut outs from aircraft fuselage and door outer skins.
A passenger door is connected to an aircraft fuselage by a hinge mechanism having an elongated goose neck hinge member.
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 door is attached to the hinge fitting 28 by way of a.
The shaft 38 is rotated by a lift lock mechanism 44 that includes a lift lock cam 106 and a cam follower.
A guide arm connected to the door and carried by the idler crank arm controls door.
This permits the use of a continuous stop on the door and body which simplifies door rigging and reduces structural weight and further increases reliability in service.
A latch lock mechanism 20 for opening and closing a translating motion type aircraft door 22.
The hinge assembly 14 includes a fitting 28 that is pivotally attached to the portion of the aircraft fuselage 14 adjacent the door opening 16 in the fuselage in which the door 10 is normally seated.
