    Abstract
  • The launching safety of explosive charge drastically affecting the application of high explosive should be used with care. The researchers are interested in the low cost and high efficiency of FAE (fuel air explosive) charged warhead. However, few references about the launching safety of the mixed fuel, especially under high launching load, can be found. In this paper, the pressure and pressure-rate in the mixed fuel during launching was analyzed by the explosion mechanics programming Object MMIC. The analysis shows that the pressure and pressure rate are different from those obtained from the traditional launching safety theory. Therefore, it is necessary for FAE weapon to establish a new launching safety theory by means of the innovative method combining the pressure wave stage with the inertia stage.
