In order to predict the explosion energy of aluminized explosives, a non-ideal detonation energy predicting mode after theoretical analysis was built and the software by matlab software, numerical iteration and numerical preparation was developed. The software is suitable for aluminized explosive C-J pressure, C-J velocity predicting of some common aluminized explosives such as H-6, HBX-1, Alex 20, Alex 32, Tritonal and Torpex. The detonation parameters and explosion energy calculated by the software agree well with empirical results and all of the deviations of aluminized explosives are less than 8%, which is useful for the explosion energy prediction of aluminized explosives.
