Abstract: A repair process for a composite material panel that forms part of a fuselage, wings, or stabilizers of an aircraft, with the panel having large dimensions and including irregular contours in some areas and edges prone to damages occurring from handling and assembly of the panel. The process a) locates the damage in the element of the composite material panel; b) sands the area that includes the damage in an area larger than the damage, makes a cut in the panel, having the cut of a same form as a piece that will serve to repair panel; c) places the piece in the cut, so that it is perfectly flush with the panel to be repaired; and d) attaches the piece to the composite material panel.

Abstract: Trailing edge (3) of an aircraft stabilizer surface (1), where this surface (1) is manufactured of a composite material and comprises an outer cladding (40) and an inner cladding (41) that are connected by a connecting clip type element (20) on this trailing edge (3), the connecting clip type element (20) comprising at its ends some recesses (23) used for coupling to the inner zone of the upper and lower claddings (40, 41) of the stabilizer surface (1), such that the connecting clip type element (20) is flexible enough to be pinched so that its ends will be housed, by means of these recesses (23), between the outer and inner claddings (40, 41) of the aircraft stabilizer surface (1), whereby the outer zone of the stabilizer surface (1), on its trailing edge (3), is formed by a continuous aerodynamic surface without changes of gradient.

Abstract: A lifting or stabilising component (11) for an aircraft comprising in the area of its trailing edge a rotary control element (13) rotating around an axis (61) with at least one slot (21) between the tip (15) of the component (11) and the control element (13), the edges of which are configured such that the distance therebetween, that is, the dimension of the slot (21), is constant for different angles of deflection of the control element (13), being located between them a seal (23) that assure the aerodynamic continuity of the component (11) when the control element (13) is at rest. In a preferred embodiment, the component (11) is a horizontal tail stabilizer and the control element (13) is a rudder.

Abstract: The invention relates to a device (1) for joining torsion boxes (5, 6) of aircraft structures, said structures carrying fuel therein, characterized in that the mentioned device (1) comprises three sides (2, 3, 4) by means of which it is secured to the inner part of the structural parts of the joint of the torsion boxes (5, 6) of the aircraft in a permanent manner, said device (1) thus closing the joint of the boxes (5, 6) and preventing possible fuel leaks, the device (1) being a non-structural component of the mentioned joint since it does not withstand the loads of the structure of the joint of torsion boxes (5, 6).

Abstract: The angular profile consists of sections (4) arranged one after another joined to each other, in order to simplify the connections between said sections (4). It is characterized in that the adjacent ends of each section (4) present in one of their sides an extension (7) complementary to a recess (8) provided in the same side of the end of the adjacent section (4) for locating the extension (7) in the recess (8) and, by means of bolted joints (9), to fix the extension (7) in the opposite side of the adjacent section (4) constituting the profile. The sections (4) and the bolted joints (9) are made of metal to provide electrical continuity. The angular profile constitutes the trailing edge of a tail rudder (1) of an HTP of an aircraft.

In a preferred embodiment, the component (11) is a horizontal tail stabilizer and the control element (13) is a rudder.

Abstract: The invention comprises an elastic material in order to carry out the joining and sealing between a first (2) and a second (3) element; and which has the aim of avoiding the formation of pinching of the sealing profile when carrying out the assembly and sealing between the first (2) and second (3) elements. For this, the sealing profile (6 and 7) presents a wedge-shaped configuration which projects with respect to the first (2) element, and on the sloping surface of which the second (3) element presses in order to facilitate its deformation and the assembly and sealing of the first (2) and second (3) element, in which position the surface of the wedge shape that projects with respect to the first element (2) presses against the second element (3). The invention is preferably applicable to aeronautical structures, particularly to those structures where both first and second elements form part of the aerodynamic surface.
