Abstract
A comparative assessment of the use of various metals and non-metals as combustible components of a solid propellant containing ammonium perchlorate as an oxidizer and rubber as a binder was performed using the range criterion of an aircraft with a ramjet engine taking into account the expected completeness of combustion of individual components. The influence of the energy properties of propellants on the technical and economic indicators and flight performance of the aircraft was also taken into account. Range calculation was carried out by numerical integration of flight dynamics equations. Based on the results, a more detailed study of a number of combustible components is recommended, in particular, for the purpose of the full or partial replacement of the currently used boron in solid propellants of ramjet engines.
