An aircraft door including a door leaf, a door frame, a support arm assembly, and first and second connecting elements. The first connecting element connects the support arm assembly with the door leaf and includes a first adjustment unit that is adapted for adjusting the position of the door leaf relative to the door frame along a first axis (x-axis). The second connecting element connects the support arm assembly with the door frame and includes a second adjustment unit that is adapted for adjusting the position of the door leaf relative to the door frame along a second axis (z-axis) that is perpendicular to the first axis (x-axis).

An actuating system for an actuatable door and to an actuatable door having such an actuating system are provided. The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

A door that is adapted to separating two environments with different pressures and to an aircraft with such a door. The door may include a door leaf, a door frame having a door stop and a roller, and an actuating system having a latch element and an inward-moving drive system. The inward-moving drive system may include a puller shaft and a puller that is non-rotatably attached to the puller shaft. The puller may include a guide rail that moves along the roller during a rotation of the puller such that the puller moves the door leaf in direction of the first environment thereby disengaging the latch element from the door stop.

Door for separating two environments with different pressures

A deceleration mechanism for a door system. In particular, a door system that is adapted to control an opening of a door module that separates compartments of an aircraft, the door module comprising a door panel that performs a rotational movement above a floor structure of the aircraft during an opening of the door module, comprises a deceleration mechanism that comprises a bolt, a bolt moving mechanism that is attached to the bolt, a latch mechanism that is removably connected to the bolt moving mechanism an activation mechanism that is attached to the latch mechanism, and a brake element that is rigidly attached to the bolt.

Door system with a deceleration mechanism

A door system with a deceleration mechanism may be adapted to control an opening of a door module that separates compartments of an aircraft and includes a door panel and a door frame. During the opening of the door module, the door panel performs a rotational movementabove a floor structure of the aircraft. The deceleration mechanism is operable in a normal operation mode and a deceleration mode and comprises a hinge, a wedge-shaped component that is rotatably attached to the hinge, and an activation device. The activation device is coupled to the wedge-shaped component and switches the deceleration mechanism from operating in the normal operation mode to operating in the deceleration mode when a difference in pressure between the compartments exceeds a predetermined threshold.

A door opening system with a deceleration mechanism may be adapted to control an opening of a door module that includes a door panel and a door frame. Deceleration mechanism may include strap that connects door panel with door frame, spool, and spool. Spool may receive one end of strap, is biased to roll up a first portion of strap, and adapted to perform a first unwinding of the first portion of strap. Spool may receive a second end of strap, is biased to roll up a second portion of strap, and adapted to perform a second unwinding of the second portion of strap from spool. Spool may include a braking apparatus that is adapted to decelerate the second unwinding when a velocity of the second unwinding is above a predetermined threshold.

An actuating mechanism () for a vent door () in an aircraft door () comprising an electric motor () driving the vent door () in a closing position towards the aircraft door (), a control unit (), controlling said electric motor (), and a flight lock actuator, driven by the electric motor (). A return spring biases the vent door () to an open position.

Actuating mechanism for a vent door

A door, especially an aircraft door, is first closed, for example manually. Then the door is first latched by a latching mechanism and locked by a locking mechanism. The latching mechanism and the locking mechanism are operatively connected through respective force transmitting couplings to a common drive in such a way that the latching mechanism is first moved to establish a latching position. Then, with a delay, the locking mechanism is moved into a locking position by the same drive to establish a latched and locked position.
