Abstract

The explosion experiments of cyclotetramethylene tetranitramine (HMX) based aluminized explosive (AE) were carried out in free filed. The shock wave parameters and heat effect data were obtained through theoretical calculation and instrument acquisition. Based on the explosion effects, a method for evaluating the power of AE was proposed. Results show that, in the experimental range, the overpressure (Δp) and impulse (I) of AE increase by 33.1% and 28.9% respectively compared with those of TNT in the largest position. The explosion fireball temperature and dimension are also much higher and greater, in high temperature range(greater than 2000℃), and the duration of AE is 7 times that of TNT. The method for evaluating the power of AE is more accurate to express its comprehensive power and helpful to compare the power of other similar non-ideal explosives.
