Effect of Aluminium Content on the Detonation Pressure and Shock Wave Parameters of TNT/Al Explosives

The detonation pressure and air explosion shock wave parameters of different aluminized explosives based TNT were tested.The influence of aluminium on the detonation pressure,air explosion parameters and shock wave overpressure was analyzed and the relationship between detonation pressure and ratio of aluminium to oxygen was built.The shock wave similarity equations for five kinds of explosives and the equation describing detonation pressure vs.shock wave overpressure were achieved.The results show that the detonation pressure decreased exponentially with the increase of aluminium content,and the shock wave overpressure reduced rapidly,while the temperature of explosive field,the maximum radius and the duration time of fireball increased.
