Abstract
In order to obtain overpressure distribution of moving cloud detonation, process of cloud dipersion and detonation was surveyed by airdrop. A high-peedmotion analyzer system and a pressure measurement system were used to measure process of cloud detonation and pressure field during explosion. Fuel dispersion and overpressure field were studied. The variation of blast parameters with propagation distance for non-stiffener structure and stiffener structure was analyzed. Results show the maxium value of peak overpressure for detonation with non-stiffenerstructure is 3.62 MPa, and with stiffener structure is 3.20 MPa. Detonation of non-stiffenerstructure has great damage range. Peak overpressure of detonation increased 31.2% with the same dose for static detonation. Mutilate distance for detonation is larger than static detonation.
