METHOD FOR FIRING OF FIGHTING VEHICLE AT TARGET (MODIFICATIONS) AND SYSTEM FOR ITS REALIZATION Russian patent published in 2004 - IPC

Abstract RU 2243483 C1

FIELD: armament and military equipment, in particular, protection of fighting vehicle against aerial attack, as well as firing, for example, in mountain conditions at elevations (depressions) of the target location with respect to the launcher.

SUBSTANCE: the accuracy and respectively the effect of fire of the fighting vehicle is enhanced firstly at firing of guns of moderate and low ballistics in mountain conditions at elevations (depressions) of the target with respect to the gun (launcher) location; secondly, at firing of small-caliber gun armament at aerial targets, especially in the near zone, as well as at a flight of the target at high altitudes. The known method for firing of a fighting vehicle at a target includes the detection and identification of target, tracking with determination of the target coordinates and parameters, determination of angular corrections: kinematic corrections for target and carrier motion, ballistic corrections (aiming angle α0 and derivation angle β0), cross wind Wz and longitudinal Wx ballistic wind speed corrections, sight and fighting machine parallax corrections from mathematical expressions, summation of them respectively in the horizontal and vertical channels with due account made for the bank angle and permanent deviation during firing with due account made for the computed angular corrections of the launcher barrels relative to the sight line. According to the invention, preliminarily before the firings, proceeding from the firing table at a zero target elevation, the dependence of the generalized parameter of function of resistance A0(D) for the projectile of each type for zero target elevation ε is determined, and after determination of the ballistic corrections, up to their summation, fighting vehicle trim θ is additionally determined, the summary target elevation with due account for fighting vehicle trim ε is determined, and sight angle αε is determined with due account for elevation angle ε from the first mathematical expression. The generalized parameter of function of resistance A is determined at an obtained value of angle αε from the second mathematical expression, projectile flight time tfl is determined from the third mathematical expression, and the angular corrections in the vertical and horizontal channels: kinematic corrections for target and carrier motion, cross wind speed Wz and longitudinal wind speed Wx, and the summary angular correction in the vertical channel is determined with due account made for obtained angle αε by way of its algebraic summation with the rest corrections.

EFFECT: enhanced accuracy and efficiency of fire.
