Abstract: The present invention relates to a curved rear pressure bulkhead (1) made of a composite material, comprising three layers: an outer layer (2) and an inner layer (3) symmetrical with one another, which are made of a fiber laminate, and the intermediate layer or core (4) made of a lightweight material. With such a sandwich-type shape, the resulting bulkhead (1) is able to withstand the bending loads coming from the strain and pressurization of the fuselage without having to increase its stiffness by means of using some type of stiffener. The bulkhead (1) comprises a ring (6) that is attached to the ends of the sandwich shape. This ring (6) is split into several parts (8) to facilitate the assembly of the bulkhead (1) made of composite material to the fuselage skin (5).

Abstract: A device for coupling a coupling pivot for a trimmable horizontal stabilizer to the tail fuselage of an aircraft, with an inner plate, an outer plate with first fastening holes and first passage holes in the inner plate respectively facing second fastening holes and second passage holes in the outer plate for the passage of a coupling pivot of the horizontal stabilizer, and with an upper lug and a lower lug respectively located above and below a cut-out for the horizontal stabilizer. The lugs are integral with separate reinforced zones of the covering in respective neighboring areas of the cut-out, in such a way that the plates between them clasp the respective reinforced zones in which the lugs are provided.

Abstract: Fitting with torsion box produced from a plastic material reinforced with carbon fiber, comprising a torsion box (2) with side walls and individual members for attaching the box to respective frames of the tail fuselage (1), along with a stiffening element (4) which joins the side walls (2a, 2b) and which comprises individual end parts (4a, 4b) and a central part (4c); where each end part (4a, 4b) comprises first sections (4d, 4e) which are extended parallel to the side walls (2a, 2b) to both sides of the central part (4c), second sections (4f, 4g) which are extended towards the corresponding side wall (2a, 2b) and third sections (4h, 4i) each one backing onto and attached to the side wall (2a, 2b); the first sections (4e, 4d) of the end parts (4a, 4b) and the side walls (2a, 2b) of the torsion box include individual primary passage holes (5a, 5b, 5c, 5d) aligned in order to create the first fastening.

Abstract: Device for coupling a coupling pivot for a trimmable horizontal stabilizer (1b) to the tail fuselage (1a) of an aircraft (1), with an inner plate (10), an outer plate (11) with first fastening holes (10a, 11a) and first passage holes (10c) in the inner plate respectively facing second fastening holes (10b, 11b) and second passage holes (11c) in the outer plate (11) for the passage of a coupling pivot (9) of the horizontal stabilizer (1b); and with an upper lug (12) and a lower lug (13) respectively located above and below a cut-out (2) for the horizontal stabilizer (1b). The lugs (12, 13) are integral with separate reinforced zones (14, 15) of the covering (1f) in respective neighboring areas of the cut-out (2), in such a way that the plates (10, 11) between them clasp the respective reinforced zones (14, 15) in which the lugs (12, 13) are provided.
