✦ Synopsis

Abstract

Burn rates of polyvinylnitrate (PVN) without and with addition of 1% by weight of ballistic modifiers, viz. carbon black, lead stearate, lead gallate and lead salicylate, have been determined at different pressures ranging form 10 kg/cm^2^ to 85 kg/cm^2^. The burn rate data show deviations from the standard ballistic equations r = a + bp and r = ap^n^. Nearly plateau burning effect is shown, at lower pressure range, by gelatinized PVN, PVN + 1% lead stearate and PVN + 1% lead gallate, whereas mesa burning is shown by PVN + 1% lead gallate (at p = 40 – 50 kg/cm^2^) and PVN + 1% lead stearate (at p = 70 to 74 kg/cm^2^).
