FIELD: armament and military equipment, in particular, firing of fighting vehicle at target, for example, with the aid of machine-gun (gun) mountings. ^ SUBSTANCE: in the known method of fighting vehicle firing consisting in target detection and identification, taking the target for tracking and tracking, determination of kinematic corrections for motion of the target and carrier, including the flight time and firing range, ballistic corrections: angle of tangent elevation and derivation, corrections for speed of cross and fair ballistic wind, for parallax of the sight and gun or machine-gun mounting from mathematic expressions, constant deviation with due account made for the barrels of the machine-gun mounting relative to the sighting line and firing at the target, according to the invention, before firings, the tables of range corrections are calculated specified for the whole range of temperature and air pressure variation for all firing ranges and approximating coefficients for pressure and temperature respectively are selected. Before determination of the sight angle the fictions firing range is determined with due account made for the deviation of temperature and air pressure from their normal values from mathematic expressions, and the sight angle is determined for the fictions range. The known system of fighting vehicle firing at a target has observation-sighting navigation systems, environment data unit, mount power drives and a machine-gun or gun mounting, on-board computer system including a unit for processing of the angle of tangent elevation and derivation, whose inputs are connected via the inputs of the computer system to the outputs of the observation-sighting system, and the outputs - to the inputs of the unit for taking into account the roll angle, whose outputs are connected to the inputs of the power drives, as well as a device for determining the angles of lead including, in its turn, the unit for generation of the angle of lead, unit for correction for ballistic wind in the horizontal channel, unit for correction for parallax in the horizontal channel, unit for generation of the angle of lead, unit for correction for fair wind in the vertical channel, unit for correction for parallax in the vertical channel, unit for generation of future range, unit for generation of flight time, whose inputs are connected via the respective inputs of the on-board computer system to the outputs of the observation - sighting, navigation systems and of the environment data unit, as well as to the outputs of the respective units included in the device for determination of the angles of lead, according to the invention, the computer system additionally uses the unit for taking into account the corrections to the angle of tangent elevation for temperature and air pressure, its first and second inputs are connected to the outputs of the environment data unit, the third input - to the output of the unit for generation of future range, and its outputs is connected to the input of the unit for generation of the angle of tangent elevation and derivation. ^ EFFECT: enhanced efficiency of fire of the fighting vehicle by enhancing the accuracy of fire due to the fact that corrections are specified in expanded ranges of temperature and air pressure variation. ^ 3 cl, 9 dwg |
