Three different explosive charges based on TNT, RDX and ADN respectively and 35% aluminium powder, were manufactured and detonated. The aim of the tests was to determine if the choice of explosive in the charges would alter the combustion of Al-powder. It was however hard to draw any conclusions from the tests. The charges based on RDX seem to give a higher impulse density and the charges based on ADN gave the lowest. The combustion temperature seems to be higher for the charges based on RDX and ADN, while the temperature for the TNT charges had a longer duration. The compatibility between ADN and activated aluminium has been measured. The results show that they are compatible if the materials are dry. Based on these results it seems that ADN can be used in formulations in combination with activated aluminium. A method to study the combustion rate of aluminium powder in different atmospheres has been developed. The method is based on combustion of Al powder in a confined vessel pressurised with the desired gas. During the test the pressure as a function of time is registered. Fast combustion of the powder results in high maximum pressure and steep pressure rise.
