METHOD OF SHOOTING WITH ARTILLERY SHELLS FROM CLOSED FIRING POSITIONS Russian patent published in 2012 - IPC F41G3/16 

FIELD: physics.

SUBSTANCE: method involves determining map range to a target, the direction angle of the target and the position angle of the target, calculating adjustments to range and direction based on firing weather conditions and the predicted initial velocity of a shell V₀, calculating firing settings using firing tables, orienting weapons, realising settings and firing. If there are no apparatus for measuring weather conditions, no data for predicting the initial velocity of a shell V₀ and apparatus for accurate orientation of weapons, two auxiliary firings are carried out in a direction. The deviation values of explosions from aiming marks are determined and then used to calculate values of range and side wind velocity W_x, W_z, the deviation of the initial velocity of a shell from the table value ΔV₀ and the orientation error Δα. Firing settings for all subsequent firings are calculated based on the obtained values W_x, W_z, ΔV₀,Δα using firing tables.

EFFECT: higher accuracy of firing when there are not apparatus for measuring weather conditions, no data for predicting initial velocity of a shell and apparatus for accurate orientation of weapons.
