Abstract
The physicochemical foundations are being developed to form propellants using the loading method. The advantages of this method include the possibility of achieving a greater packing density of the particulates, no requirement for the use of costly equipment, and the absence of mechanical operations that could pose a risk of fire or explosion. The determined values were dimensions, helium and bulk density, closed pore content, (the content of intergranular spacing and open pore), and the thermal stability of ammonium perchlorate (AP) granules originating from various sources. The obtained materials differed in terms of size, sphericity, bulk density, closed pore density, (the content of intergranular spacing and open pore). The granulate having the greatest sphericity and bulk density was determined based on tests. The measurements, sphericity and density of aluminium dust originating from various sources were established. The pot life of the prepolymer cross-linking agent (diisocyanate) system was specified. Cross-linking agents with a pot life exceeding 3 hours at a temperature of 70ºC were selected. Based on the tests, materials were selected for the formation of heterogeneous rocket propellants using the loading method. The propellant samples created using the loading method were characterised in terms of their physicochemical parameters.
