Study on performance and safety characteristics of multilayer composite propellants

Abstract. Solid propellants have become indispensable in propulsion systems, particularly in rocket engines, where they are used in over 90% of aerospace applications. Advances in propellant technology, especially the development of multilayer propellants, have addressed the need for more precise burn rate control. This study focuses on the formulation and experimental evaluation of multilayer composite propellants. Two propellant mixtures were developed and configured in parallel layers for testing. This research investigates the safety and performance characteristics of multilayer composite propellants through a series of rigorous tests. Key parameters, including density, burn rates, friction and impact sensitivity, heat of combustion, thermal stability, mechanical sensibility were studied, as well as closed vessel tests were performed in order to determine ballistic properties.
