EFFECT OF ORGANIC COATINGS OF NANOALUMINUM ON THE BURNING RATE OF MIXED COMPOSITIONS

ABSTRACT
Mixed compositions based on ammonium perchlorate, inert fuel-binder and nanosized aluminum, encapsulated with organic compounds, have been experimentally studied. The study of aluminum powders using scanning electron microscopy and transmission electron microscopy was carried out. The oxidation of aluminum powders was investigated by differential thermal and thermogravimetric methods. The chemical composition of the condensed products was determined by X-ray diffraction. The laws of mixed composition combustion were determined in a wide pressure range. The possibility of controlling the burning rate and the content of condensed combustion products by using encapsulated nanoaluminum is shown.
