[ 1 ] - مقایسه پایداری شیمیایی دو نمونه پیشرانه یک پایه و دوپایه با استفاده از آزمون های کهولت تسریع یافته و روش آنالیز حرارتی DSC
Chemical stability in propellants is important issue. In this article chemical and thermal stability for two kinds of double and single base propellants are investigated. In mass loss test in 90 0C, after 18 days mass loss for both samples is no more than 3%. By stabilizer measurement it was evident that remaining stabilizer content in aged samples are more than 10% in relative to fresh samples...

Determinations of lifetime for propellants require exact evaluation of thermal decomposition kinetic parameters. Thermal analysis is one of the tools for investigation of thermal decomposition reaction and its kinetic parameters. In this article, thermal decomposition process for a single-base propellant is investigated under 1, 2 and 3 K/min heating rates. Then by using Friedman isoconversiona...
[ 3 ] - پیش بینی طول عمر شیمیایی یک نمونه پیشرانه بر اساس مدل‌های سینتیکی متفاوت
Propellants are decomposed slowly during storage. So each propellant has useful life time which more than that time propellant is not safe and cannot used. Tracing of propellant stabilizer consumption is one of the important methods for determination of storage life time period of a propellant. In this article by accelerated aging on a double-base propellant and then chemical extraction of stab...
