Apparatus for opening and closing an aircraft electric door

An aircraft electric door for a pressurized airframe (1) comprising:

• a locking system (S4) for locking a safety catch (43, 4a, 4b);
• a moving system (110, 200, 300) for opening and closing a door arm (6);
• a single electric motor controlled by a door computer and adapted to actuate (2, 21, 210) the locking system (S4) and the moving system (110, 200, 300);
• wherein the moving system (110, 200, 300) includes:
• a mobile cylindrical support including a guideway (51, 511, 512) linked to the door arm (6), the mobile cylindrical support is rotatable by the electrical motor, the guideway (51, 511, 512) being partially helical along a vertical axis (Z′Z) of the mobile cylindrical support (50);
• and
• a fixed guide (9, 91, 92) includes a vertical camway (9v, 91v, 92v) and a horizontal camway (9h, 91h, 92h) to guide the door arm (6) as the door is moved by the single motor between an open position and a closed position, the horizontal camway prevents the door arm (6) from vertically moving during a pivoting of the door and the vertical camway prevents the door arm (6) from pivoting during a vertical lifting of the door;
• wherein the door arm (6) is pivotable relative to a vertical hinge (61) and is linked with door lifting devices (7a, 7b, 8, 62), the door lifting devices being mounted between a shaft of the safety catch (43) and the door arm (6);
• wherein the mobile cylindrical support is mobile sleeve (501) mounted on a vertical column (20) and rotated by the single electric motor (2), the mobile sleeve comprising the guideway which receives a guiding slider (631) mounted on the door arm (6);
• and the fixed guide is coaxial with the mobile sleeve and is adapted to drive a second guiding slider (632) mounted on a hinge yoke (60) of the door arm, wherein said hinge yoke includes a bore (601) which receives the vertical column (20) passing through the bore of the hinge yoke.
