Abstract

To predict the system accuracy, we should calculate the measure of the muzzle velocity error and elevation difference according to 1 m/s change of muzzle velocity. The magnitude of the muzzle velocity may be obtained by weighed sum of three quantities: the percentage errors of projectile weight, propellant weight and the volume of the chamber. The elevation difference according to 1 m/s change of muzzle velocity can be obtained from the multivariable function. The inputs of the multivariable function are: the distance that the bullet falls due to gravity, the distance from the launch position to the target, muzzle velocity, tangent angle from the launch position to the target. The error on the target due to muzzle velocity error can be a product of two quantities: the measure of the muzzle velocity error and elevation difference according to 1 m/s change of muzzle velocity. To predict the system accuracy, we use the accuracy function having the standard deviation and then we may obtain the system accuracy.
