Overall study of a new concept of drilling bomb

Accompanying with the stronghold and subterranean of the defence system, conventional weapons have to be more and more powerful. Except for improving on the conventional warhead and composite warhead earth-penetrating weapon, new kinds of the earth-penetrating weapon are brought out day after day. In the paper, a new concept of earth-penetrating weapon called digging bomb with the skilled technique on digging is brought out. Starting with high speed digging theory, the overall structure of the system, the working function mechanism and the working process of every part are analyzed. At last, the key technology of the system is discussed.
