BLU-113 is earth penetrator warhead commonly used. It has been simulated by using LS-DYNA finite-element software to analyze damage effectiveness of BLU-113, which BLU-113 attacks underground protective works under different deepness from 10 to 22 m. In the simulation, shotcrete layers, anchor-hold rocks and loose rocks are taken into account. The penetration process and explosive process of BLU-113...
Explosion damage effect of Massive Ordnance Penetrator (MOP) is more than 10 times the explosive power of its predecessor, the BLU-109. The targets of MOP will be deeply underground headquarters and hard deeply buried targets. It has been simulated by using LS-DYNA finite-element software to analyze damage effect of MOP, which MOP attacks underground protective works under different deepness from...
Based on the structure of left-handed transmission line (LH-TL), a novel phase shifter with higher power capacity is designed here. In the present structure, switches of phase shifters are mounted on fingers of LH-TLs, so the electric current through a single switch is only a fraction of that through the whole phase shifter. As a result, the power capacity of present phase shifter can be greatly improved...
