Disposición de junta de elementos estructurales de un material compuesto en componentes que comprende un revestimiento y una pluralidad de elementos estructurales, aplicable a parejas de un primer y un segundo elemento estructural (11, 21) que se cruzan, tales como una viga y una cuaderna en un fuselaje de una aeronave, teniendo ambos elementos una configuración que incluye unas almas (31, 41), unas faldillas interiores (33, 43) Y unas faldillas exteriores (35, 45), en la que en la zona de cruce entre dichos elementos (11, 21) el laminado de una ó las dos faldillas (33, 35) del primer elemento (11) incluye unas solapas transversales (53, 55; 57, 59) que se unen a una o las dos faldillas (43, 45) de los extremos de los segmentos (23, 25) del segundo elemento (21) que quedan separados en el cruce, sirviendo de medios de paso de cargas entre ellos.
Abstract:
The invention relates to a torsion box skin stiffened with non-parallel stringers. More specifically, the invention relates to a torsion box of an aircraft airfoil, comprising a front spar (15), a rear spar (17), ribs (21) and upper and lower stiffened skins. According to the invention, at least one of the skins (31) is stiffened with a plurality of stringers (33, 43), preferably omega-stringers, which all extend over the entire span of the skin, preferably in a conical arrangement, and which have a cross-section that decreases towards the outer edge of the skin.
Abstract:
Aircraft fuselage made out with composite material and manufacturing processes. The structure of the fuselage (1 1 ) comprises a skin (13), a plurality of frames (17) positioned transversely to the longitudinal axis (9) of the fuselage (11) and a plurality of longitudinal stiffening elements (14, 15) that can be either stringers (14) or beams (15), being the ratio between the distance (X) between frames (17) and the distance (Y) between longitudinal stiffening elements (14, 15) is less than one. If the stiffening elements are stringers (14) the manufacturing process is based on assembling the fuselage section (11) joining the skin (13) with the stringers (14) to the frames (17). If the stiffening elements are beams (15) the manufacturing process is based on joining the skin to an internal structure made up with frames (17) and beams (15).
Abstract:
Support pylon (19) for aircraft engines joined to a section of the fuselage (17) that has a curved closed cross-section including a skin (31) and a plurality of frames (33); its structural configuration comprising a central box (41) inside the fuselage and two external lateral boxes (51, 61) on both sides of it, all of which are made of composite material, the three boxes (41, 51, 61) being structured as multi-spar boxes with upper and lower skins (43, 45; 53, 55; 63, 65), lateral spars (47, 49; 57, 59, 67, 69) and at least one central spar (48, 58; 68); having an entirely continuous interface between the central box (41) and the skin (31) of the fuselage; being joined to the fuselage (17) maintaining total continuity in the skin (31) of the fuselage and full load transfer between any frame interrupted (33') where it reaches the central box (41).
Abstract:
The invention relates to a device (1) for installing a conducting component (2) on a structure (3) made of compound material, the inside of said structure (3) including a starter substance, that includes an installation element (4) on which the conducting component (2) is placed, a conducting insertion element (5) by means of which the installation element (4) is connected to the inside of the compound material structure (3), a conducting layer (6) disposed on the outside of the installation element (4), and a conducting fastener element (7) that connects the structure (3) and the installation element (4) with the insertion element (5) and the conducting layer (6) such that the device (1) determines a low impedance current path through the conducting layer (6) and the insertion element (5), by means of which the energy is dissipated from an atmospheric discharge on the component (2) or on the structure (3), keeping the inner side of the structure (3) isolated.
Abstract:
Joining arrangement for two boxes (11, 11') of composite material with an intermediate part (31) and method for producing said intermediate part (31). The join is effected using rivets between the skins (15, 15'; 17, 17') of said boxes (11, 11') and the upper and lower flanges (33, 35) of said T-shaped part (31). The production method comprises the following steps: a) Providing two C-shaped preforms (41, 41'), configured such that their webs (43, 43') are parallel to one another and their upper and lower flanges (55, 55'; 57, 57') are approximately parallel to the end zones of said skins (15, 15'; 7', 15'); b) Providing two flat preforms (45, 47) to reinforce the flanges (35, 37); c) Shaping and curing the part (31) from said preforms (41, 41', 45, 47) using an RTM method.
Abstract:
A repair process for a composite material panel (1) that forms part of the fuselage, the wings or the stabilizers of an aircraft, with the panel (1) having large dimensions and having irregular contours in some areas, comprising of edges (2) prone to damages occurring from the handling and assembly of said panel (1), characterized because it comprises of the following steps: a. Locating the damage (3) in the element (2) of the composite material panel (1); b. Sanding the area that comprises the damage (3) in an area larger than said damage 3, making a cut (9) in the panel (1), having said cut (9) being the same form as piece (7) that will serve to repair panel (1); c. Placement of the piece (7) in the cut (9), so that it is perfectly flush with the panel to be repaired (1); d. Attachment of the piece (7) to the composite material panel (1).
