METHOD TO CONTROL CANNON FIRING BY CONTROLLED PROJECTILE Russian patent published in 2011 - IPC F41G5/08 F41G5/14 

FIELD: weapons and ammunition.

SUBSTANCE: method includes gripping of a controlled projectile after firing with a homing system, measurement of projectile deviations from an aiming line, transfer of control commands to it, supplying signals to its control elements that correspond to these commands. Additionally the zero line of aiming is calibrated, generated and aligned with the aiming line of the information area of the projectile control. Distance is measured between the information plane of the controlled projectile capture and the cannon, directions of linear deviations are identified from the independent stabilised aiming line of longitudinal axes of the cannon barrel channel and the information area of the projectile control. For the time of capture the longitudinal axes of the cannon barrel channel and the information area are moved towards previously identified directions to the independent stabilised line of aiming at the angles, tangents of which are equal to ratios of linear deviations in the capture plane from the independent stabilised line of aiming of longitudinal axes of accordingly the cannon barrel channel and the information area of control to the distance of the controlled projectile capture plane from the cannon.

EFFECT: increased efficiency of cannon and missile armament by compensation of external disturbances caused by inaccuracy of their compensation at the initial section prior to start of control, and also by structural features of cannon and sight arrangement.
