The invention relates to a skid-type landing gear () for a helicopter () comprising bow shaped crosstubes (-) directed symmetrically towards a left- and a right-hand side of a longitudinal mid axis () of the helicopter () with respective skids () at outboard ends thereof and main beams (-) in a fuselage (), the crosstubes (-) being connected to the main beams (-) via supports (-) fixed to the main beams (-). The skid-type landing gear () is retractable. A method for operating such a skid-type landing gear () for a helicopter () is provided.

Skid-type landing gear for a helicopter

An airplane door is swivellably disposed on a supporting arm, the supporting arm being swivellably disposed on an opening frame of a fuselage, and including a driving device for lifting and lowering the door and another driving device for swivelling the door and the supporting arm. During the movement of the lifting or lowering of the door, the transmission line of the driving device for the swivelling is uncoupled so that it is not unnecessarily mechanically stressed and a jamming of the transmission line therefore basically does not occur.

Arrangement for moving an airplane door swivellably disposed on a supporting arm

An aircraft door has an inner framework integrally connected to an outer skin by simultaneously casting the framework and the skin in a mold that holds a single core for each frame element in the form of a rib in a freight door or a beam in a passenger door. The ribs extend circumferentially relative to a longitudinal central axis of the aircraft. The beams extend in parallel to the central aircraft axis. The single core is selected from at least one core type and four core types at the most. The frame elements in the form of ribs or beams have open arches for a considerable weight reduction.

Aircraft door and mold for casting the door

A method and an arrangement for adjusting a door-side safety device of an airplane door is provided to further improve the ergonomics for the operation of the door. A safety shaft of a safety device arranged on the door side can be adjusted by a coupling device by a driving device arranged on the frame side between the locked condition and the secured locked condition. The safety shaft arranged on the door side is coupled by way of a coupling device arranged between the door and the frame with the driving device arranged on the frame side and connected by way of the operating shaft. This arrangement allows an operation of the door in the cabin interior by an operating element which is arranged on the frame side next to the door opening. By means of this operating element, it is possible to control the movement of the door and to generate a door-side movement of the safety device by way of a movement of a device arranged on the frame side, so that the door can be secured in the locked condition, or the securing can be released in the locked condition.
