A SINGLE CHART SYSTEM OF INTERIOR BALLISTICS

Abstract

A graphical method which has been used in the Interior Ballistics Laboratory during the past few years to make estimates of the interior ballistic performance of guns is presented. This method utilizes a chart which gives rapid solutions to some common problems in interior ballistics. The Mayer-Hart assumptions were made in writing the equations on which the chart is based. It was also assumed that bore friction is proportional to chamber pressure. This is equivalent to giving the projectile an effective mass somewhat higher than its actual mass. This assumption provided a factor which could be tailored to bring chart and experiment into closer agreement. The data from 165 firing records were compared with the chart and a form for the effective mass of the projectile was determined which considerably improved the agreement of chart with experiment.
