A twin-rotor side-by-side compound rotorcraft has a fuselage and variable incident wing assembly that pivots rela-tive to fuselage. The aircraft also has landing gear assembly and a tail fin assembly. The variable incident wing assembly is piv-otally attached to the fuselage, and includes wing members, engines fixedly mounted to the wing members or another area of the rotorcraft, and a mast attached at a fixed angle relative to the wing members. Then engines may also be located near the fuselage or another area of the rotorcraft. The variable incident wing assembly is capable of pivoting about a pivot axis, thereby allowing mast orientation in at least a hover mast position and a forward flight mast position. The rotors provide additional forward thrust and the wings provide additional lift, when the mast is in the forward flight mast position.

L'invention porte sur un giravion composite à double rotor côté à côté, qui a un fuselage et un ensemble aile incidente variable qui pivote par rapport au fuselage. L'avion a également un ensemble train d'atterrissage et un ensemble dérive. L'ensemble aile incidente variable est fixé de façon pivotante au fuselage, et comprend des éléments d'aile, des moteurs montés de façon fixe aux éléments d'aile ou à une autre région du giravion, et un mât attaché à un angle fixe par rapport aux éléments d'aile. Ensuite, les moteurs peuvent également être situés à proximité du fuselage ou d'une autre région du giravion. L'ensemble aile incidente variable est capable de pivoter autour d'un axe de pivotement, permettant ainsi une orientation du mât dans au moins une position de mât en vol stationnaire et une position de mât en vol vers l'avant. Les rotors fournissent une poussée vers l'avant supplémentaire et les ailes fournissent une portance supplémentaire, lorsque le mât est dans la position de mât en vol vers l'avant.
