METHOD OF GUN LAYING AND DEVICE FOR ITS REALIZATION Russian patent published in 1998 - IPC

FIELD: weapon, in particular, gun laying control, applicable in gun laying systems. SUBSTANCE: entire range of the point of impact is divided into N intervals. The respective system of three ballistics equations is assigned to each interval. Prediction of coordinates of the point of impact is accomplished for nominal conditions. Signals of correction for the angle of sight, azimuth and range are determined for the present conditions of fire. The signal of present range to the point of impact is determined by summation of the signal of predicted range to the point of impact and signal of range correction. Prior to simulation of the shell ballistics, the interval comprising the signal of present range to the point of impact is determined. The shell ballistics in this interval is simulated by the respective system of three equations. Laying signals are generated by summation of signals corresponding to the angles of prediction of the point of impact, correction signals and ballistics simulation signals. The intervals are taken to be equal to 200 to 1000 m. The gun laying device uses series-connected target tracking system, prediction unit of coordinates of the point of shell impact with the target correction unit, as well as a ballistic unit, the first and second adders, whose outputs are connected to the gun elevation and training drives, and the third adder. The ballistic unit is made as a set of packets, each using three operational amplifiers, it realizes one of the N systems of ballistics equations. Logic units tuned to definite ranges to the point of impact are installed at the input of the packets. The logic unit, whose range comprises the present range to the point of impact, participates in operation. The number of logic units and packets corresponds to the number of intervals in the range to the point of impact. EFFECT: enhanced accuracy of fire at range from 1.5 km to the maximum range. 5 cl, 4 dwg
