DISENO DE CUADERNAS DE AERONAVE

摘要

The invention relates to a reinforcing frame (1) of the fuselage (2) of an aircraft, said fuselage (2) comprising a skin (3) and stringers (20), the mentioned frame (1) comprising a structural member (4) and a closed, internally hollow honeycomb member (5), the structural member (4) comprising a lower base (6) which is arranged on the inner face of the skin (3) of the fuselage (2), and through which the stringers (20) connecting the frames (1) to the rest of the structure of the fuselage (2) pass, and upper reinforcing members (7) on which the mentioned honeycomb members (5) are arranged, such that the honeycomb members (5) increase the inertia and the stiffness of the frame (1) without adding weight thereto, the frame (1) having high stiffness in the transverse direction, in addition to being intrinsically stable to local buckling.
