Abstract：The impact energy release characteristics of an energetic jet was analysed based on the building of a dynamic energy acquisition system.The overpressure versus time curves produced by the energetic jet impinging plate were obtained under different impact conditions, and the composition of reaction products was determined.The results show that with the increase of the impact energy, the overpressure peak and energy release formed by the jet both show a tendency to increase progressively, and there is an upper limit of impact energy which can make the energetic material reach the staurated state of chemical reaction.The average amount of heat that the jet can release is 65.4 kJ containing 4.4 g, which is enough to achieve damage.
