Various Carbon Materials Action on the Burning Rate Modifiers of Low-Calorie Double-Base Propellant

Accounting for super-, plateau- and mesa-rate burning by lead and copper-based ballistic modifiers in double-base propellants: a computational study

“…The first denotes the low-pressure, super-rate burning effect (i), which reaches a peak (ii) with respect to activity of the modifier as the amount of carbon in the flame steadily increases to a maximum -an effect well documented in the literature. 14,38,50,51 After the maximum, the effect of the modifier diminishes as higher gas pressures are reached and the carbon levels fall (iii); this follows directly from the carbon-soot theory, i.e. the reduction of carbon levels from the burning surface is responsible for the drop in burn rate.…”

Influence of some additives on burning rate of KNO3-based compositions

“…However, CNTs have a high thermal conductivity greater than soot, and a developed structure [29]. So, when the combustion of compositions containing CNTs occurs, a higher carbon frame is formed on combustion surface and covering a larger burning surface area, on which catalyst particles accumulated (much more than in the case of soot [24,25]). This increases the effective surface area of the catalyst particles, where intense heat is generated, leading to an increase burning rate.…”
