Abstract: An attachment arrangement for attaching a component to a base item, with at least one fixing device for fixing one section of the component on a section of the base item. At least one connecting device with a connecting element and at least one receiving element are provided. One of the elements is arranged on a component section and the other of the elements is arranged on a base item section. The two elements detachably engage with one another in a form fit. Loads can be transferred at least in the direction of a first axis, and a relative movement is possible between the elements in the direction of a second axis, different from the first axis. A connecting device is disclosed for such an attachment arrangement. A method is disclosed for purposes of attaching a component to a base item by means of such an attachment arrangement.

Abstract: An aircraft door arrangement having a pivotable door for closing an aperture in the fuselage of an aircraft and selectively movable between closed and open positions by a linear actuating mechanism having a casing and a rod selectively extendable and retractable. An actuator mounting mounts the casing between two elements of the primary structure of the aircraft. The rod is pivotally coupled to the door. The actuator mounting includes a rigid mounting component including three legs extending in a common plane together with the casing and the rotation axis and each having a first and a second longitudinal end. The first and second legs symmetrically extend from the casing at an angle at opposite sides thereof. Each of the second ends of the first and second legs is rotatably coupled on the rotation axis to another one of the spaced elements of the primary structure of the aircraft.

Abstract: Inter alia, an apparatus including a ramp, the ramp configured to enable variation of a cross section of a ram air passage of the apparatus. The ramp includes a first rigid member, a second rigid member and a flexible member coupled to the first rigid member and the second rigid member. The ramp is movably mounted at two ends. Moreover, a method of varying the cross section of the ram air passage of such an apparatus by moving the ramp of the apparatus is disclosed. Further, an arrangement including such an apparatus and a ram air channel communicating with the ram air passage is disclosed.

Abstract: A method for coupling a first and a second stiffening element for a skin of an aircraft or spacecraft, wherein the first stiffening element has a cross-sectional profile with first and second web portions extending from a flange portion of a predefined width toward the skin includes forming a coupling zone of the first stiffening element wherein the second web portion is at least partially removed to expose an inner surface of the first web portion, and a step of fastening a coupling element, for coupling the stiffening elements, to the coupling zone of the first stiffening element.

Abstract: A method of manufacturing a shell component for an aircraft or spacecraft includes positioning a skin panel, which includes a skin of the aircraft or spacecraft and first and second stringers stiffening the skin, opposite a frame having first and second mouseholes for receiving the first and second stringers, elastically bending the skin panel, inserting the first stringer into the first mousehole, and releasing the elastic bend to insert the second stringer into the second mousehole.

Abstract: A manufacturing method for passenger door corner components of aircraft or spacecraft includes using additive layer manufacturing, ALM, to form an integral passenger door corner component. The integral passenger door corner component includes a substantially cruciform shape having a frame coupling member with two frame couplings as end pieces. The frame coupling member intersect with a beam coupling member with two beam couplings as end pieces.

Abstract: A cover plate for covering a door clearance between a skin of a means of transportation and a door as well as a door arrangement with such a cover plate is proposed. The cover plate includes a mounting region for permanently fastening the cover plate on the door; a covering region for covering the door clearance; and a fastening device that is designed for fixing the covering region on the skin when the door is closed.

Abstract: An aircraft frame comprising a first partial aircraft frame configured to be attached to a first aircraft fuselage segment and a second partial aircraft frame configured to be attached to a second aircraft fuselage segment is provided. The first partial aircraft frame and the second partial aircraft frame are configured to be connected to each other to be in a connected configuration forming the aircraft frame such that the first fuselage segment and the second fuselage segment are connectable.

Abstract: An aircraft fuselage structure having a first fuselage barrel section and a second fuselage section barrel which are joined by tension fasteners extending through frame holes. A shank diameter of the fasteners is smaller than a respective frame hole diameter. A first positive locking element and a second positive locking element is provided forming a form-fit area with the first positive locking element in the circumferential direction. A method for producing such an aircraft fuselage section is also provided.
