Abstract
Disclosed is a multi-spar torsion box structure comprising a plurality of spars of composite material arranged to form a multi-cell structure with two or more cells extending longitudinally along the torsion box, and upper and lower skin covers formed of composite material and joined to upper and lower surfaces of the multi-cell structure, respectively. The structure further comprises at least one belt-like reinforcing element extending around the outer perimeter of the torsion box, and fixed to the upper and lower surfaces of the multi-cell structure, and transversely arranged with respect to the longitudinal direction of the torsion box. The belt-like reinforcing element is made of a metallic or a composite material. The disclosed torsion box can advantageously be used in the manufacture of aircraft lifting surfaces, such as horizontal tailplanes (HTP) or wings.
