|Currently, a strip charge is coiled around itself and placed in a foil bag prior to use. This method of storage causes cracks in the strip charge that prevents detonation and destroys the intended use of the strip charge. In addition, the tightly wound strip charge develops a shape memory which prevents natural unraveling of the strip charge after being secured to a target structure.
Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented an effective and efficient storage arrangement for an elongated flexible strip charge. This technology not only protects strip charges from cracks, but also minimizes the tendency for the strip charge to assume a shape memory. The storage arrangement includes a spool with a central aperture that is placed at the end of the strip charge. The channel extends from the central aperture out to a peripheral wall around which the strip is wound. The channel slightly curves, preventing excessive strip charge bending. In addition, the removable spool is attached to a base plate that maintains the strip charge in place prior to use.
