Abstract:

The range of an artillery projectile is considered to be a function of 1 muzzle velocity, 2 ballistic air density, 3 ballistic air temperature, and 4 ballistic range wind. Based on the assumption that the statistical distributions of these four parameters are normal and independent, optimum unit range effects for these parameters are obtained -- having the property that their use minimizes the expected value of the square of the error which results from the use of unit range effects. A numerical example is considered involving Cartridge, 105mm, HE, M1 and, finally, the theory is extended to show how to obtain optimum plus and minus unit range effects for each parameter -- i.e. one unit effect to be used when the deviation of the parameter from its standard value is positive, and another unit effect to be used when this deviation is negative.
