Abstract

To decrease uncertainties of projectile muzzle velocities is one of important ways to improve gun firing accuracy. In order to solve the problem above, the influences on the uncertainties of projectile muzzle velocities should be calculated, which are caused by the variations of artillery structure parameters, but there is no effective method. We will provide a valid solution in this paper, taking a wheeled self-propelled gun for example. Firstly test scheme is designed and computed in inter-outer array. Subsequently the influences of barrel and projectile's parameters on the fluctuations and means of projectile muzzle velocities are discussed based on experimental results. Then in the next analysis their contribution rates to the fluctuations and means of projectile muzzle velocities are calculated and these parameters are classified further to improve gun firing accuracy better. At last, test scheme and results are proved to be reasonable and feasible.
