The present invention relates to an aircraft horizontal tail plane (HTP) having a multi-rib torsion box formed by first (1a) and second (1b) lateral torsion boxes symmetrically arranged with respect to a plane of symmetry (X-X) of the horizontal tail plane (8). A group of ribs (4a,4b) are substantially parallel to the plane of symmetry (X-X) of the horizontal tail plane (8), and stringers (7a,7b) are arranged so as to define an angle within the range 80°-100° with respect to the plane of symmetry (X-X) of the horizontal tail plane (8). Due to this relative arrangement of the ribs (4a,4b) and stringers (7a,7b), the stringers (7a,7b) are not continuous through ribs (4a,4b), thus the ribs (4a,4b) can be manufactured without mouse holes. The HTP (8) of the invention can be manufactured easier and faster than traditional HTP designs. |
