## 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 deviati

Abstract
The addition of burning rate enhancers or suppressers in solid propellant composition is seen to affect the energy level considerably. In the present paper, an attempt is made to quantify such effects. Even though the study is carried out over the theoretical values of the performance parameters, the trends in the variations and the corrections occurring therefrom for the inclusion of burning rate modifiers seem to be applicable to the delivered or the actual values also more or less equally.

Burning rates of phenol-formaldehyde composite propellants based on NH4CI04, KCIO4, NaNOa, and KNO a oxidisers are measured under the pressure of nitrogen at 1-95 atm. The burning rate laws of the type (P[r) = (a + bP) and (P/r) = (a + bP21 a) are tested. It is revealed that the latter gives a super
