SYSTEM FOR CORRECTING TRAJECTORY OF ROTATING ARTILLERY SHELL Russian patent published in 2025 - IPC F42B15/01 

FIELD: weapons.

SUBSTANCE: invention relates to military equipment, in particular to head fuses of artillery shells rotating in flight. Rotary artillery projectile trajectory correction system consists of part rotating together with projectile (RP), containing a rotor of a generator with permanent magnets or a toothed non-winding rotor of an inductor generator, and a part stabilized (SP) relative to the Earth, installed on RP with possibility of free rotation relative to it around a common axis, comprising a safety actuator, a generator stator with windings, a control system with a receiver and an antenna for signals of a global satellite navigation system and/or signals of the local navigation system and sensors of the inertial navigation system, as well as two pairs of aerodynamic surfaces (AS) rigidly mounted on the SP body, providing creation of aerodynamic lifting force, correcting projectile trajectory, and aerodynamic moment opposite to projectile rotation direction, providing generation of electric energy by generator and stabilization of SP relative to Earth in required position. AM are installed on the outer surface of the SP body so that one pair of AM can create an aerodynamic lift, and the second pair of AM can create an aerodynamic moment, or both pairs of AM are installed on external surface of housing of SP so that each of AC can create both aerodynamic lift and aerodynamic moment.

EFFECT: higher combat effectiveness of rotating projectile.
