Abstract: An aircraft door, and, more particularly, to an electromechanical door system for operating an aircraft door that closes an opening in the outer hull of an aircraft, as well as to a method of operating an electromechanical door system of an aircraft door that closes an opening in the outer hull of an aircraft. The electromechanical door system may be adapted for operating in a normal opening mode, an emergency opening mode, and a closing mode. If desired, the electromechanical door system may include a lifting and lowering lever, a lifting and lowering electric motor, and a gearbox that transmits a force from the lifting and lowering electric motor to the lifting and lowering lever.

Abstract: An aircraft door, and, more particularly, to a mounting system for a pressure seal of an aircraft door. A mounting system may include an outer skin, a pressure seal, a clamping component, a pressure seal fastener having a head and a threaded shank, a nut, a mounting support having a clearance hole that is adapted to prevent a rotational and axial movement of the pressure seal fastener, and mounting support fasteners. Mounting support fasteners removably attach the mounting support to the outer skin. The head of the pressure seal fastener is connected to the mounting support such that a rotational and axial movement of the pressure seal fastener is prevented. The nut is removably attached to the threaded shank of the pressure seal fastener, thereby removably clamping the pressure seal between the clamping component and the mounting support.

Abstract: The invention relates to a stop armature of an armature system of an aircraft door with a fuselage stop armature (10) and a door stop armature (12, 79), with a stop screw (30; 40; 60) in one of the two stop armatures (10, 12 or 79), which can be pressurized by the other stop armature (10) in the longitudinal direction of the screw (30; 40; 60; 80) on a locating face (34; 52; 70; 88). It is further developed by virtue of the fact that the screw (30; 40; 60; 80) encompasses a screw head (32; 42; 69) with a ball (36; 50; 68; 85) held therein that can rotate around its midpoint (M) as the fulcrum. The invention also relates to a stop screw for a stop armature and the use of a ball thrust screw as the stop screw.
