Abstract
The inventive hollow charge comprises a body (1) in the form of an open shell, explosive material (2) which is placed therein and is provided with a hollow cavity arranged in the open section of the body (1), a triggering device (3) arranged in the closed section of the body (1) and a lining (4) which is adjacent to the hollow cavity and has a relief formed by irregularities (5) dependent on the undulations of the shape and the thickness thereof. One or more pads (6) which in part or totally separate the explosive material (2) from the charge body (1) can be placed layer-by-layer without gap on the inner surface of the body (1). A lining (4)is designed in the form of a solid body which is adjacent to the hollow cavity and is limited by two surfaces, the thickness of which is less than the other sizes thereof, in general, the thickness of lining being variable. The corrugated lining can be considered as a special case of a relief lining when the reliefs of the two lining surfaces are in agreement with each other. The optimal distribution of distances between the relief strips is determined the material of the lining (4), the thickness thereof at different sections and by a pressure generated by explosion of the explosive material (2). The best piecing results are obtained when the middle wavy line of the lining (4) sections along the generating lines of the relief have a wavelengths within a range of (0,3÷0,7)hlin. L/H, and a bent having a length of (0,5÷1,5)hlin.L/H is formed on the side of the open section of the body, where hlin. is the mean thickness of the lining (4) at the wavelength of interest, L is the wavelength of the initial disturbances of a plate, with a thickness H, increasing most rapidly, and the L/H ratio between a specific material and the used explosive material is determined by statistically treating the results of corresponding experiments. Said invention makes it possible to increase the performance characteristics and the piercing capacity of the charge, to simultaneously reduce the production cost and provide the stability of the results of use thereof.
