Abstract

Aluminum nanoparticles modified with various additives (Ba, gasoline, and organosilicon resin) were obtained by arc plasma recondensation. The chemical composition, morphology, and thermal properties of nanoparticles and the characteristics of combustion of energy-producing condensed systems containing nanoaluminum were studied experimentally. The structure of the particles was determined by X-ray diffraction (a Rigaku Geigerflex diffractometer), transmission electron microscopy (JEM 2000 EX-II), scanning electron microscopy (JEOL JSM 7401F), atomic force microscopy (SOLVER P-47), and differential scanning calorimetry (NETZSCH STA 409). The replacement of aluminum powder with micron particles with nanodisperse aluminum increased the rate of combustion of stoichiometric compositions on the basis of ammonium perchlorate by an order of magnitude at a pressure of 40 atm. Simultaneously, the mean linear diameter of agglomerates collected from the surface of combustion decreased from 28 to 2 μm. The results are evidence that the use of energy-producing condensed compositions with nanoaluminum offers much promise for increasing the effectiveness of solid fuel rocket engines.
