Abstract

ABSTRACT
The energy output of high explosives can be increased by the addition of certain
metallic fuels to the explosive compositions. Aluminum is the most common fuel
additive due to its high reliability and low cost as well as its high heat of
combustion. In this paper, aluminized high explosive compositions based on
RDX, TNT and aluminum powder (12, 40, 75 μm) were prepared on the Lab
scale. In these compositions, the weight percentage of aluminum was 5, 10, 15,
20 and 25 %. Some of the explosive characteristics of the compositions were
determined experimentally and theoretically. The effects of weight percentage and
grain size on the characteristics of such compositions were recognized.
