EXTENDED SHAPED CHARGE AND METHOD FOR ITS MANUFACTURE Russian patent published in 2002 - IPC

FIELD: explosion engineering, applicable in explosion cropping of spread obstacles, various configured objectives. SUBSTANCE: extended shaped charge may be produced in the place of its use by arrangement on the surfaces to be spotted of empty molding fragments with a shaped recess and open ends and an elastic cylindrical bag common for all fragments inserted in them that takes the shape of an extended shaped charge in the places of arrangement of the molding fragments and the shape of an extended cylindrical charge between them when it is filled with a liquid explosive. The method consists in the following. Empty molding fragments with a shaped recess are placed on the surfaces to be separated, an elastic cylindrical bag that is common for all fragments is passed through them, in the sections between the fragments the bag is enclosed in guard tubes and filled with a liquid explosive. EFFECT: reduced cost of cropping of configured objectives. 9 cl, 2 dwg
