CROSS-BEAM FOR SUPPORTING A STRUCTURE OF AN AIRCRAFT AND ASSOCIATED AIRCRAFT

摘要

The invention relates to a cross-beam (30) capable of supporting a structure (20) of an aircraft. The cross-beam (30) comprises: a first flange (35) extending lengthwise along a longitudinal axis (X) and widthwise along a transverse axis (Y), said first flange (35) including an inner surface (40) and an opposing outer surface (43); a second flange (36) extending parallel to the first flange (35) and comprising an inner surface (41) and an opposing outer surface (44), the inner surfaces (40, 41) of the two flanges (35, 36) being disposed facing one another; and a web (37) linking the two flanges (35, 36) and extending along a vertical axis (Z). The cross-beam is characterised in that the web (37) comprises two half-webs (38, 39) connected by a securing means (25), namely: a first half-web (38) solidly connected to the first flange (35), and a second half-web (39) solidly connected to the second flange (36). The first half-web (38) and the first flange (35) are made from an electrically conductive metal material, while the second half-web (39) and the second flange (36) are made from a composite material.
