摘要:
为了研究大装药扇形壳体结构燃料空气炸药（FAE）云雾的发展和变化特征，为下一步的云雾爆轰提供依据，通过高速相机和无人机观测了装药量为300 kg的扇形壳体结构燃料的爆炸抛撒和雾化过程。结果表明：燃料在各个方向上的运动速度存在差异，导致最终云雾形状不规则，为带有许多条状突出的五角星形状；云雾临爆前的浓度为70 g/m3，燃料与空气中氧气的化学当量比为0.46；对于300 kg燃料，最佳二次起爆延迟时间为300 ms。最佳二次起爆位置在扇形壳体45°或315°方向、距离中心4.2 m处。
Abstract:
The dispersion and atomization process of the sector-shaped shell structure with a charge of 300 kg fuel was observed by high-speed video recording and drone to understand the development and variation characteristics of fuel air explosive (FAE) cloud in large charge sector structure and to provide a theoretical basis for further cloud detonation. The results show that there is a difference among the speeds along various directions, thus creating an irregular shape for the cloud, i.e. a five-pointed star along with many strips. Cloud concentration before burst is 70 g/m3, and the chemical equivalent ratio of fuel to oxygen in the air is 0.46. For 300 kg fuel, the optimal secondary detonation delay time is 300 ms. The optimum secondary initiation position is 4.2 m from the center and along the 45° or 315°directions of the sector shell.
