Investigations of the detonation characteristics of new aluminum‐enriched RDX‐based composites belonging to the enhanced blast explosive formulations were undertaken. Firstly, the explosion heat was measured in a calorimetric bomb filled with argon and after the cylinder expansion test was performed. From the cylinder test data the wall velocity, the Gurney energy and the detonation energy of the composites were determined. Then, using simulations, the isentrope exponents of the composite detonation products were estimated and hence the detonation pressures were calculated. Finally the equation of state of the detonation products was determined for each composite from the calorimetric heat and from the cylinder test data. The investigation results are presented and discussed. The effect of the aluminum particle size on the detonation characteristics is also checked. Conclusions about how to use these composite in weapon systems to generate optimal effects are drawn.
