- Аннотация: This study investigated the combustion behavior of tetramethylammonium perchlorate (TMAP)compositions with inert additives, ammonium perchlorate (AP), and in AP-based composite propellants. The explanation for the lack of the combustion of TMAP in its pure form is given. It is postulated that the addition of inert substances, such as Al2O3 and carbon nanotubes (CNTs), to TMAP increases the heat input from the gas zone due to their higher thermal conductivity. This compensates for the heat loss from the reaction zone in the condensed phase, which leads to the occurrence of combustion. As the Al2O3 content increases or CNTs are used, the heat input from the gas phase also increases significantly, causing the burning rate to be determined by the kinetics of the rapid decomposition of a TMAP dissociation product, methyl perchlorate, in the gas zone. Studies on the combustion of mixtures of AP and TMAP have demonstrated that when introduced into a system with the leading reaction in the condensed phase, TMAP acts as an inert additive due to its higher thermal stability and lower heat release rate compared to AP. In compositions with propellants that burn by the gas phase mechanism, dissociative vaporization of TMAP results in the formation of thermally unstable methyl perchlorate in the gas zone, which acts as a rapid heat release agent.
