Beschreibung
Zusammenfassung:	The invention provides an aircraft lifting surface with a torsion box (13) of a composite material comprising an upper skin (21), a lower skin (23), a front spar (18), a rear spar (20), one or more intermediate spars (19, 19') and a plurality of transverse ribs (25, 25', ...) arranged between the rear spar (20) and its adjacent intermediate spar (19') and/or between the front spar (18) and the adjacent intermediate spar (19) for improving its structural behavior. The invention also provides a manufacturing method of said torsion box.
