Abstract

Various embodiments including an improved shaped demolition charge apparatus and methods associated with the invention are provided in a cylindrical dynamic access structure (“CDAS”), which can include a wave shaper, a main charge, and a booster disk. An exemplary embodiment comprises a waver shaper, and a main charge, which can be plastic, bonded explosive. A wave shaper can comprise of two-layered structure in which a void is formed. A wave shaper can be disposed between a booster disk and a main charge such that the booster disk is only in contact with the main charge along an outer edge of the booster disk. A wave shaper directs or channels a shock wave from the booster disk to an outer portion of the main charge. A container can be formed or adapted around a cover, booster disk, main charge, and wave shaper.
