| Description: | Combustion velocity is an important parameter for the formulation of pyrotechnic compositions. It is affected by several parameters that are studied in this work. Pyrotechnic compositions studied are ternary compositions composed of an oxidiser, a metallic reducer and a binder. This binder is also an energetic molecule. These three components are, respectively, strontium peroxide (SrO2), magnesium (Mg) and 2,4‐dinitroanisole (DNAN). The fabrication, thermal degradation and combustion velocities of these compositions were already published. The aim of this work is to study the influence of selected parameters on the combustion velocity of pyrotechnic composition. These parameters were identified, and dimensionless numbers were settled. Multilinear regressions were performed using these parameters and dimensionless numbers. The obtained coefficients show the influence of each parameter. It was possible to increase regression coefficient using crossterms and doing regressions separately before and after the maximal burning velocity. Results show different joint influences of the parameters before and after this maximum, especially concerning the main chemical reactions. A methodology was also proposed to obtain the reducer ratio of a given composition that would give the maximal burning velocity. |
