CANARD CONTROL (VERSIONS) Russian patent published in 2014 - IPC B64C9/10 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Canard control incorporates version of all-moving feathering front horizontal canard. In compliance with first version, said front horizontal canard features the following twist of fins: fin support root section positive angle of attack is larger than that at support ends. In compliance with second version, said front horizontal canard features variable relative thickness of fins: larger nearby root of fins and smaller nearby the ends of supports. In compliance with third version, said front horizontal canard features weather vane shaped to regular triangle, isosceles triangle, skew-side triangle or skew-side rhomb. In compliance with fourth version, said front horizontal canard incorporates electrical remote control that allows smooth decreased in transmission factor in transmission line from pilot master to actuator "angle between front horizontal canard and weather vane" or smooth input of negative shift in said angle. In compliance with fifth version, it is equipped with computer system. System processor receives the signal from control master, from transducer of angle between weather vane and fins, signals of pitch, speed and height while processor output is connected with vertical rudder actuator.

EFFECT: better anti-spin properties.
