FIELD: aircraft structural members.
SUBSTANCE: proposed aircraft structural member includes sheets of skin and several rigidity profiles connected with skin section by weld seam. Rigidity profiles have rigidity members formed by duplicating components made in form of I-profiles; each of them is located on sections of profile struts on at least one side. Rigidity members may be formed by tie rods mounted on sections of profile struts which have thickened areas of material with holes for introducing the tie rods.
EFFECT: enhanced residual strength; cut costs.
