An aircraft having a canard aerodynamic configuration (see fig. 4) comprises a mechanized wing, which is not shown in the drawing, and also a canard foreplane (10) with a servo flap (3), which are pivotally mounted on the axis of rotation ОО1. The lift coefficient derivative of the canard foreplane with respect to the angle of attack of the aircraft increases from zero to the required amount as a result of the angle between the reference planes of the canard foreplane (10) and the aircraft changing relative to only a part of the change in the angle between the reference planes of the servo flap (3) and the aircraft as the angle of attack of the aircraft changes. To this end, a mechanism consisting of elements (11), (12) and (13) is used. For pitch control, the axis ОО3 can be displaced towards axis ОО1 or away from same, and the position thereof is fixed by a rod (14), which is an element of the control system. The invention is directed toward reducing the area of the wing by equalizing the cruise workload of the canard foreplane therewith. |
