Abstract
From the results of calculations, it follows that the addition of aluminum (Al) and aluminum hydride (AlH3) significantly increases the potential energy content of HMX. This parameter is higher in the case of Al-containing mixtures. However, the compositions with AlH3 form a considerable number of moles of gaseous products in distinction to the mixtures with Al. The acceleration ability (AA) of aluminized compositions was measured with the use of the method known as M-40 (acceleration of a steel plate from the end of a charge inside the thick-walled steel shell). Furthermore, the AA values were calculated for the systems containing Al and AlH3. The results of studies demonstrated the possibility of increasing AA of high explosive (HE) by adding both Al and AlH3. In the case of HMX (HE with negative oxygen balance (OB)), the AlH3 -containing compositions are inferior to the Al-containing ones in AA. The greatest increase in AA with the addition of AlH3 should be expected in the case of HE with positive OB (such as bis(trinitroethyl)nitramine), the compositions with AlH3 therewith should be superior to the Al-containing systems in AA.
