Abstract: A rotor or propeller may have rotor blades and a passive pitch angle adjustment apparatus. The passive pitch angle adjustment apparatus may include levers, rods, and central rod. Levers may be connected to rotor blades and rotate them around a respective pitch axis. Rods may be connected to levers and mechanically link levers with each other via central point that is located outside rotor plane. Central rod may connect central point with base point that is located in a longitudinal direction of rotor axis. The passive pitch angle adjustment apparatus may enable a cyclic pitch adjustment of the rotor blades and block a collective pitch adjustment of the rotor blades.

Abstract: An aircraft pressurized cabin door includes an integral door structure unit made of fiber composite, the unit including an outer skin and a door framework arranged on an inner side of the outer skin. The framework includes a plurality of edge supports and a plurality of longitudinal supports extending in a width direction between the edge supports so as to form door framework interstices delimited by the inner side of the outer skin, by the edge supports and by the longitudinal supports. The door framework interstices are configured in a manner open toward the inner side of the door.

Abstract: A loads interface (1) of an aircraft structure with an edge member (6) and a background structure both preferably made from fiber reinforced plastics. A loads transferring flange (2) is adapted and mounted to said edge member (6) to transmit bending moments into the background structure. Said loads transferring flange (2) is provided with two angled upper and lower planes (8, 9). Said edge member (6) is provided with two angled edge member's upper and lower transfer planes (10, 11). The two angled upper and lower planes (8, 9) and the two angled edge member's upper and lower transfer planes (10, 11) are paired essentially parallel and respectively oriented to each other with an angle of approximately 90°. The invention relates as well to applications of such a loads interface (1).
