Formulated Composition And Combustion Properties

In this study, we discussed the influence of the difference of RDX content and Pb₃O₄ on the combustion properties of TEGDN propellant. The combustion properties of TEGDN propellant were evalucated by closed bomb tests. The results showed that the buring rate of TEGDN propellant containing RDX increased with the increasing of RDX's content,but it was lower than TEGDN propellant's buring rate;burning rate pressure exponent for TEGDN propellant containing RDX increased with the increasing of RDX's content. Burning rate pressure exponent for TEGDN propellant containing RDX and Pb₃O₄ decreased with the increasing of pressure. TEGDN propellant containing RDX could be catalyzed to decrease its burning rate pressure exponent by Pb₃O₄.
