Abstract

Background/Objectives: The objective of this paper is to predict probability of hit for an anti-aircraft artillery based on the errors of the muzzle velocity and the cant error related to the fire power. Methods/Statistical Analysis: The muzzle velocity is obtained by using Le Duc equation and the errors of the projectile and the propellant. The cant angle error is obtained by the rotation of coordinate system and the cant sensor error. Then the root of the sum of squares of errors gives us the total error and then by using the equation of probability of hit, we may obtain probability of hit for an antiaircraft artillery. Findings: The muzzle velocity error due to the projectile weight error, the propellant weight error and the chamber volume error are obtained. The cant angle error due to cant angle sensor error may be obtained. Assume that all the errors are given, then we obtain the total errors in the horizontal error and the vertical error. Then using the total errors and the equation of probability of hit, we obtain probability of hit for an anti-aircraft artillery. Improvements/ Applications: When we design a combat vehicle, this approach will be good resources for performance analysis of fire power for an anti-aircraft artillery.
