Abstract

In order to solove the problem of prematurecombustion from a twicedetonating large scale FAE warhead for 300 kg, the warhead and its related structures are improved and verified. By analyzing the cloud morphology captured by highspeed video, it is considered that the main causes of prematurecombustion are: the unreasonable structure of central charge leads to excessive axial impact; the physical stability of raw fuel is poor, and the sensitive components will flash under the action of explosion products after the upper end plate is broken. To solve these two problems, the warhead is improved as follows: Tshaped interval charge is used to replace cylindrical charge, reduce the charge at the initiation end, control the radial propagation of detonation wave, and replace the raw fuel with liquid fuel with lower sensitive component content. After taking the above measures, there is no prematurecombustion in the process of fuel dispersion. The overpressure in the cloud detonation zone is greater than 2.0 MPa, and the static detonation power obtained by overpressure fitting is about 5. 5 times TNT equivalent.

Key words： FAE; warhead; twice-detonating; premature combustion; safety
