METHOD OF SURFACE-TO-AIR PROJECTILES FIRING TO AIR TARGETS Russian patent published in 2018 - IPC F42C9/00 F41G5/14 

FIELD: military equipment.

SUBSTANCE: invention relates to the military equipment, and in particular to methods of conducting combat against aerial targets using artillery ammunition. Invention can also be used during the anti-aircraft missiles and shells remote fuses development. Anti-aircraft shells firing method implementation consists in the following. With the air target detection, the firing artillery unit determines the target coordinates and its movement parameters using various tools. Using known techniques based on the obtained data on the target and the selected parameters of firing with artillery gun, calculating the projectile detonation zone location with respect to the target. At that, calculating the target altitude H. For a given target altitude H, using measurements and calculations calculating the atmospheric pressure value P_n in the projectile assumed explosion zone. To calculate the pressure, performing the atmospheric parameters instrumental measurements are in the gun area, namely, measuring the pressure P₀ and temperature T₀. According to known data, determining the air temperature T_n at the altitude of N. Pressure P_n is calculated using the known barometric formula by the measurement data and other environmental parameters substitution into this formula. Calculated value of atmospheric pressure in the area of target P_n is entered into the projectile fuse with the help of the installer in the form of mission data. In the projectile installing the fuse with the static atmospheric pressure measuring device. This device main element is the pressure sensor. After the shot, using the pressure sensor performing the pressure in the projectile zone continuous measurement. Comparing the measured value with the pressure P_n, entered into the fuse computer as the mission data. At the time of the measured pressure reaching the P_n value the fuse issues impulse for the projectile detonation.

EFFECT: invention allows to increase the an anti-aircraft projectile detonation accuracy at the calculated location.
