BALLOT2 - A Computer Program to Analyze the In-Bore Motion of a Projectile Launched in a Stationary Smooth Gun Tube

Abstract

This work documents the BALLOT2 computer program which may be used to compute the in-bore or balloting motion of a projectile launched in a stationary smooth gun tube. The term smooth gun tube means that the gun tube has straight rifling only or nor rifling at all. The presentations include all the main equations, the program symbols or codes, the flowcharts, the preparation of the input data, the output of computation results, the operation of the program, and the program usage. The program may compute the effects of eccentricity of projectile c.g., axial c.g. location, rotating band properties, projectile dimensions, initial projectile position, bore diameter, friction forces, air resistance, etc. The results of computations are arranged to be printed out in tabular form, plotted in figures, and recorded on a magnetic tape. An example is included to show the data arrangement and the computed results.
