DEFINITION

Classification: 102/306

Shaped charge or charge with detonation wave cavity modifier:

(under subclass 305) Subject matter wherein the explosive charge (a) has a cavity in its external surface, or (b) has a material next to the charge with a cavity in its external surface, the charge upon detonation produces a detonation wave front determined by the shape of the cavity.

(1) Note. Included in this group of subclasses, per se, or combined with the cavity is a liner conforming to the shape of the cavity. The cavity upon detonation of the charge produces a wave front, dependent on the cavity shape which acts on the liner to propel the liner and shape the liner into a jet stream of high energy.
