The respective embodiments and developments are provided in the subclaims .
The invention provides an aircraft fuselage structure with frames running in the circumferential direction, stringers running in the longitudinal direction and a skin which is arranged thereon and outwardly seals the aircraft fuselage in a compression-proof manner. According to the invention, it is provided that the aircraft fuselage structure contains prefabricated integral units which each run in the circumferential direction of a fuselage segment and in which the frame of a fuselage segment and connecting elements for connection to skin elements comprising stringers and skin are formed.
Furthermore, the invention provides an integral unit for an aircraft fuselage structure with frames running in the circumferential direction, stringers running in the longitudinal direction and a skin which is arranged thereon and outwardly seals the aircraft fuselage in a compression-proof manner.

Finally, the invention provides a method for producing an aircraft fuselage structure with frames running in the circumferential direction, stringers running in the longitudinal direction and a skin which is arranged thereon and outwardly seals the aircraft fuselage in a compression-proof manner.

Exemplary embodiments of the invention are explained below with reference to the drawing, in which: Fig. l(a) shows a plan view and (b) a side view of an integral unit which is provided for an aircraft fuselage structure according to an exemplary embodiment of the invention;
Figs 2 (a) and (b) show respective connecting elements for connection of an integral unit of the type shown in Fig. 1 to skin elements, comprising stringers and skin, according to one exemplary embodiment of the invention;
Figs 3 (a) , (b) and (c) show a schematic illustration of a method for producing an aircraft fuselage structure, in which prefabricated integral units and prefabricated skin are joined together to form an aircraft fuselage structure, according to one exemplary embodiment of the invention.
Fig. 1 shows an integral unit 10 which serves for the production of an aircraft fuselage structure which is to contain frames running in the circumferential direction, stringers running in the longitudinal direction and a skin which is arranged thereon and is intended for the compression-proof sealing of the aircraft fuselage to the outside. The integral unit 10 shown in plan view in Fig. l(a) and in side view in Fig. 1 (b) contains a frame 11 of a fuselage segment, i.e. a plane intersecting the aircraft fuselage perpendicularly with respect to its longitudinal direction, and connecting elements 18, 19, which will be illustrated in more detail further on, for connection to skin elements comprising stringers and skin.
In the exemplary embodiment illustrated, the integral units 10 are each prefabricated in one piece and run in an annularly completely closed manner over the entire circumference of a fuselage segment. The integral unit 10 comprises a main body which runs in the plane of a fuselage segment and forms the frame 10, and connecting elements 18, 19 which protrude therefrom and are intended for the connection to skin elements comprising stringers 22 and skin 21. These connecting elements 18, 19, which are illustrated in more detail in Figs 2 (a) and (b) , comprise a force- transmission comb 18 which is formed by teeth protruding perpendicularly with respect to the main body of the integral unit 10, which main body forms the frame 11. The skin elements 20 are fixed in a frictional or interlocking manner to said teeth. The fixing can take place by riveting by means of titanium bolts, as also can the closing of longitudinal seams between the skin elements 20.
As Fig. 1 shows, the integral units 10 contain a hold cross member 12, a hatrack stiffening means 13 and a main cross member 14 , The hold cross member 12 is supported against the main body of the integral unit 10 by respective supporting elements 15, 15a, the hatrack cross member 13 is supported against the main body of the integral unit 10 by respective supporting elements 16, 16a, and the main deck cross member 14 is supported against the main body of the integral unit 10 by respective supporting elements 17, 17a. In the exemplary embodiment illustrated, the hold cross member 12, the hatrack cross member 13 and the main deck cross member 14 and also the supporting elements 15, 15a, 16, 16a and 17, 17a thereof are designed as integral, single-piece components of the integral unit 10.
The integral units 10 of the exemplary embodiment described are produced from fibre-reinforced plastic, namely from carbon- fibre-reinforced plastic.
The production of the integral units 10 can take place, in particular, in one operation, with all of the necessary components being produced in one piece, i.e. integrally. Production can take place, in particular, in a negative mould in such a manner that tolerances which occur are each apportioned to the side which is unimportant for installation, i.e. on the internal flange of the main body of the integral unit 10, which main body forms the frame, and on the lower side of the cross members 12, 13 and 14.
The integral formation in the integral unit of all of the support and connecting elements occurring in a fuselage segment, together with the weight-saving CFRP construction described reduce the weight and increase the strength, and a large number of joining and connecting points between the respective elements are omitted.
A method for producing an aircraft fuselage structure according to the invention is to be described below with reference to Fig. 3. Said method contains the production of the integral units 10 of the type described above, which are required for the aircraft fuselage structure and contain the frame 11 of a fuselage segment, the connecting elements 18, 19 for connection to skin elements 20 comprising the stringers 22 and the skin 21, and the cross members 12, 13, 14 and the supporting elements 15, 15a, 16, 16a and 17, 17a, and optionally further elements which are not illustrated specifically here. Furthermore, the skin elements 20 which contain the skin 21 and the stringers 22 are produced. Furthermore, the skin elements 20 may already be completed with window frames, door frames and the like. The completed integral units 10 are illustrated in schematic form in Fig. 3 (a). The integral units 10 are then arranged on an installation apparatus 30 and adjusted, and the skin elements 20 are mounted on the integral units 10 and are connected thereto, as illustrated in schematic form in Fig. 3 (c) . During the production of the skin elements 20, glass- fibre and aluminium composite tabs ("GLARE") can be provided at critical points, in particular at those which are subsequently located in the region of the integral units 10. Composite tabs of this type are formed by a laminate of layers of a thin sheet of an aluminium alloy and a textile fibre material, that is a woven fabric or insert of glass fibres or similar suitable fibres which are alternately layered one above another. Composite tabs of this type serve to compensate for different thermal coefficients of expansion of light metal alloys and fibre-reinforced plastics. Their composite structure enables them to adapt the different coefficients of expansion of the materials involved. Composite tabs of this type can also be provided at the connecting points of skin elements 20 adjacent to the skin 21.
Frame angle brackets 18 which are formed on the integral units 10 are riveted to the skin elements 20. All of the longitudinal members to be provided in the aircraft fuselage structure, such as seat rails and the supports thereof, are then introduced and bolted down.
The skin shells 20, the skin 21 thereof and the stringers 22 thereof can be produced from a fibre- reinforced plastic material (CPRP) or from light metal. If they are not composed of a fibre-reinforced plastic material, the different thermal coefficients of expansion of integral unit 10 and skin element 20 have to be dealt with by the force-transmission comb 18, the riveting and the skin 21 in the circumferential direction. A compensation of different thermal coefficients of expansion can take place by means of the above-described glass-fibre and aluminium composite tabs. Composite tabs of this type can also be used in order to strengthen the skin elements 20 against possible large longitudinal tears if the aircraft fuselage structure is subjected to unusual stresses. The aircraft fuselage structure produced in the manner described can then also be supplemented by a cockpit unit and a corner section, which supports the tail unit, to provide the complete aircraft fuselage.
