Investigation of Mechanism of Plateau and Mesa Burning in Double Base Solid Propellants

Double base solid propellant burning rate is highly dependent on the pressure, so that the combustion duration propellant rocket engines, combustion vibration leads to considerable changes in pressure. This could lead to an explosion in rocket engines. The best case is propellant combustion independent of pressure. Ballistic modifiers added to propellant formulation for reduce pressure sensitivity and reduce or increase of burning rate also. Lead and copper salts are materials that create plateau and mesa in double base propellant. In this article, effective ingredient in creation of plateau effect in double base propellant investigated. Some of these ingredients are particle size, concentration, dispersal, decomposition temperature and ability of ultraviolet ray of catalyst. In addition to, mechanism of create plateau and mesa in noncatalysed double base propellant and also empirical, radically and preckel mechanisms of create plateau and mesa for lead catalysts in double base propellant investigated.
