METHOD OF SHOOTING WITH ANTI-AIRCRAFT PROJECTILE 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. Implementation of the proposed method of firing anti-aircraft shells is as follows. When an air target is detected, the firing artillery unit using various tools (goniometers, range finders, etc.) determines the coordinates of the target and its movement parameters (direction, flight speed, etc.). Using known techniques, based on the obtained data on the target and the selected parameters of firing artillery guns (estimated initial velocity of the projectile V_p and elevation angle α), calculate the location of the zone of explosion of the projectile in relation to the target. To clarify the value of the initial velocity of the projectile continuously, using pressure sensors and temperature, measure the pressure P_i and temperatures T_i air in the area of the projectile from the very beginning of the reference time of the projectile (time t₁). In a short time Δt=(t₂-t₁) where t₂ – time at the moment corresponding to pressure P₂, t₁ – time at the moment corresponding to pressure P₁, calculate the actual initial velocity of the projectile V_i. For this purpose, data on the measurement of air pressure and temperature at various altitudes using pressure and temperature sensors are used. Rated speed V_p, used when calculating the trigger time of the fuse t_p, is clarified, namely V_p is used instead of V_i. Calculated new fuse response time t_pi injected into the propeller fuse with the help of a computing device fuse as a flight task.

EFFECT: invention makes it possible to increase the accuracy of an anti-aircraft projectile detonation at an estimated location.
