Patent ID: 7896288

Claim:
A method for improving the roll steering of an aircraft of large dimensions comprising: a fuselage, two wings symmetric with respect to said fuselage, provided with controllable aerodynamic surfaces configured to produce a roll movement for the aircraft, and a vertical fin projecting upwards with respect to the rear part of said fuselage and provided with a rudder extending along the rear edge of said fin and configured to turn, with respect to said vertical fin, about an axis of rotation, said method comprising: dividing said rudder, transversely to said axis of rotation, into at least two individual rudder elements disposed successively along said axis of rotation and being independently controllable in rotation about said axis of rotation, and when said wing aerodynamic surfaces are deflected so as to communicate a roll movement to said aircraft in a determined direction: deflecting at least one of said individual rudder elements disposed farther from said fuselage in said determined direction of roll, and simultaneously, deflecting at least one of said individual rudder elements disposed nearer to said fuselage in the opposite direction.
