AN INTERIOR BALLISTIC ANALYSIS OF A HIGH-LOW PRESSURE GUN USING NOZZLE-START, SHOT-START AND SECONDARY IGNITER MATERIAL

Abstract

Interior ballistic equations suitable for computer analysis are developed to predict the performance of the 40mm grenade launcher M79 firing the multiple projectile cartridge XM576. These equations take into account the effects of the nozzle-start and shot-start pressures which are characteristic of this system. Also considered is the effect of secondary igniter material upon the ballistic performance. An isothermal model is used for the period during which the propellant is burning. Only propellant of constant burning surface area is considered.
