Claim 0:
1. An aircraft (1, 1′, 1″) comprising:
a fuselage (2) with an axis (A) of longitudinal extension; and
a tail portion (14) arranged at a tail end (13) of said fuselage (2); said tail portion (14) comprising two surfaces (15a, 15b) arranged in a V-shape, inclined with respect to each other and symmetrical with respect to said axis (A); each said surface (15a, 15b) comprising an associated winglet (19a, 19b) arranged transversally with respect to the associated said surface (15a, 15b) and fixed with respect to the associated said surface (15a, 15b); said first and second surfaces (15a, 15b) comprising:
respective first faces (17a, 17b) facing each other;
respective second faces (18a, 18b) opposite to the respective first faces (17a, 17b); and
respective end edges (16a, 16b) opposite to said fuselage (2) from which the associated said winglets (19a, 19b) extend; each said winglet (19a, 19b) comprising:
a respective first portion (20a, 20b) extending in a cantilevered way from the associated end edge (16a, 16b) on a side of said respective first face (17a, 17b); starting from the associated said end edge (16a, 16b), said first portions (20a, 20b) being convergent to one another;
wherein each said winglet (19a, 19b) further comprises a respective second portion (21a, 21b) extending in a cantilevered way from the associated end edge (16a, 16b) on a side of said respective said second face (18a, 18b);
starting from the associated said end edge (16a, 16b), said second portions (21a, 21b) being divergent from one another;
wherein a median plane of each said winglet (19a, 19b) is parallel to a median plane of each said surface (15b, 15a) from which the other said winglet (19b, 19a) extends.
