Abstract
An explosive device is disclosed which comprises a cylindrical casing filled with explosive charge. The charge is covered at one or both of its sides by a fragmentable lining which is fragmented by explosion of the explosive charge and movement of the shock wave in an effective direction. A recess is provided in the explosive charge which contains an inner booster charge surrounded by an outer annular booster charge. The inner and outer booster charges may be separated by a thin wall with openings in the wall communicating with spaced in the recess on sides of the outer booster charge. A damming lining covers a part of the outer booster charge and is spaced from the outer booster charge to form the spaces.
Claims18
An explosive device comprising:
- a case in the form of a body of rotation about a central axis and defining an open face;
- an explosive charge in the case;
- at least one fragmentable lining covering the open face and the explosive charge, the explosive charge shaped to explode and fragment the lining substantially in an effective direction parallel to the central axis;
- the explosive charge having a recess therein symmetrical about the axis and extending in the explosive charge and symmetrical about a central vector of the effective direction;
- an inner booster charge substantially at a center of the recess;
- an outer booster charge positioned around the inner booster charge and extending into the recess;
- and
- damming means covering at least a portion of the outer booster charge made of non-explosive shockwave attenuating material and between the outer booster and the liner.
A device for initiating an explosive charge with a predetermined effective direction, particularly a charge provided with at least one lining which forms piercing fragments to be projected, comprising, a first booster charge ignitable by means of a detonator, a second outer concentric booster charge, the two booster charges being received within a recess provided in the explosive charge which is symmetrical in the predetermined effective direction of the explosive charge, and disposed in positions coaxial with an axis of symmetry of the recess, with the recess and the outer booster charge extending into a peripheral zone of the explosive charge in a direction transverse to the predetermined effective direction, and a damming lining over the surface of the outer booster charge and in the recess extending transversely to the predetermined effective direction made of an inert non explosive material.
