GUIDED PROJECTILE Russian patent published in 2018 - IPC F42B15/00 F42B10/62 

FIELD: weapons.

SUBSTANCE: invention relates to the field of weapons, in particular to the field of small-sized guided projectiles, mainly with subsonic and transonic flight speeds, and can be used in constructions with various aerodynamic schemes. Guided projectile, designed in the aerodynamic scheme "duck", contains a cylindrical body and a head part with a fairing, a steering unit and aerodynamic controls. Aerodynamic controls are made of a steering wheel, the arms of which are installed on the side surface of the head part fairing, and pylons rigidly fixed to the body in front of the rudder arms in the same plane. Consoles of the steering wheel and pylons are made of flat plates with airborne chords, installed on the side surface at an angle of 5–15 degrees to the longitudinal axis of the missile. Steering wheel is made with a rotational spanwise angle along the leading edge – 0 degrees from the root chord to 0.30–0.40 of the swing of the steering wheel console, then with a sweep angle of 55–65 degrees to the full swing of the steering wheel console. Swing of the pylon console is made with a ratio of 0.30–0.40 swing of the steering wheel console. Pylon side chord is made with a ratio of 0.40–0.50 to the length of the side chord of the steering wheel, and the gap between the leading edge of the steering wheel and the rear side of the pylon is 0.05–0.15 of the length of the side chord of the steering wheel console.

EFFECT: invention increases the effectiveness of the projectile control, its dynamic and ballistic characteristics, increases the flying range of the projectiles.
