ABSTRACT:
A pivoting coupling system of a large dihedral empennage to the tail fuselage of an aircraft, in which the empennage includes a right lateral box and a left lateral box arranged at a large dihedral angle in the tail fuselage of the aircraft. The pivoting coupling system including a horizontal central box joining the lateral boxes, and which includes a rear spar; and a linkage for horizontally linking the central box to a frame structure of the tail fuselage of the aircraft, which allow the empennage to rotate vertically about a horizontal linkage shaft between a negative maximum angle of incidence and a positive maximum angle of incidence in response to the actuation of an actuator which is connected to the empennage and to a structural element of the fuselage of the aircraft.
