AIRCRAFT OF FEATHERED CANARD ARRANGEMENT (KRASNOV-CANARD) Russian patent published in 2017 - IPC B64C39/12 B64C13/16 

FIELD: transportation; aviation.

SUBSTANCE: aircraft (AC) of aerodynamic feathered canard arrangement comprises a high-lift wing and a feathered horizontal canard (FHC) (10) with a servo tab (3), which are hingedly placed on the axis of rotation OO¹. The rate of the FHC lift force coefficient by the angle of attack of the AC increased from zero to the necessary value due to the fact that the angle between base planes of FHC (10) and AC varies only by a part of the angle variation between the base planes of the servo tab (3) and AC with AC angle of attack variation by a mechanism from elements (11, 12, 13). For pitch steering, the axis OO³ may move towards the axis OO¹ and away from it, at the same time its position is fixed by a traction rod (14), being the element of the control system.

EFFECT: reduced area of a wing due to balancing of cruising workload of a feathered horizontal canard with it.
