Flame Atomic Absorption Spectrometric Determination of lead and titanium in samples of double‐base propellants

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.

Effect of Burning Rate Modifiers on Propellant Performance. A theoretical study

This article presents an efficient numerical algorithm for determining, for a given metallized propellant system, the optimum combination of reactants which can fetch the maximum specific impulse, and also the salient features of the associated computer program. The optimization procedure is based on the Fletcher-Powell technique with the objective function being augmented by a penalty term to accommodate the constraints. Numerical results for the optimization, obtained by means of a computer program written in FORTRAN IV on the IBM-360 computer for a representative propellant system, are also presented in this note.
