The Law And Characterization Of Energy Release In High Aluminized Explosives

In order to guide high aluminized explosive prescription design, the main components impact on the energy release were studied, the methods of theoretical calculation,static detonation in opened space, static detonation in confined space and underwater explosion test were taken.By means of computational about detonation velocity, detonation pressure, detonation thermal, heat of explosion, detonation temperature and heat of combustion, the variation of the main components impact on the parameters calculated were obstained.The RDX/(RDX+AP) and aluminum content impact on the energy release of high aluminized explosive were studied by the method of static detonation in opened space. The effects of the main components on overpressure and impulse of shock wave and the maximum temperature and maximum diameter of explosion fireball were analyzed.The aluminum content impact on the energy release of high aluminized explosive was studied by the method of static detonation in confined space, and the laws of overpressure and impulse of shock wave were analyzed. By designing a calibration method of multi-line temperature measurement system, we obtained aluminum radiation signals under detonation state. Then the dynamic explosion temperature was measured and the law was abstained, it shows that the explosion temperature could up to3300K, the temperature of after combustion can reach to1500K and maintaine for a long while; and the process of explosion was studied from the point of explosion temperature.The underwater explosion is the most appropriate method for measure the explosion energy of TBE.The laws of aluminum content, the atmosphere type and pressure of the atmosphere influence on the shock wave energy, and total energy bubbles were studied by the method of underwater explosion.
