A Prediction on Dispersion Accuracy of the Gun-vehicle System in Self-propelled Anti-aircraft Gun

From vehicle, gun, projectile and charge system, a basic principle has been presented for the first time in the paper by making use of the random-simulation technology based on the theory of interior ballistic, automat, vibration of self-propelled gun system, initial disturbing and external ballistic etc. The basic principle is achieved by simulating a movement procedure of the gun-vehicle system on firing and by predicting dispersion accuracy on targets with computer. According to this basic principle, we programmed the predicting software about dispersion accuracy of the gun-vehicle system in self-propelled anti-aircraft gun, finally by comparing the result from computer simulation with the data of firing practice in shooting range. Hence the identical result in testing proves that the principle of this researching method is correct and practical. The method can be used in research on dispersion accuracy of other guns or artillery as well and possesses a certain reference value.
