Claims (1)

Устройство заряда кумулятивного перфоратора, содержащее металлический корпус, заполненный взрывчатым веществом, промежуточный детонатор, установленный на торцевой стенке корпуса, и расположенную с противоположной стороны корпуса кумулятивную выемку с облицовкой, обращенную своей вершиной в сторону детонатора, причем между детонатором и вершиной выемки находится экран из инертного материала, который при срабатывании детонатора огибается волной детонации, препятствуя прохождению последней напрямую к вершине выемки, отличающееся тем, что экран расположен в непосредственной близости от детонатора и образует с торцевой и боковой стенками корпуса канал для прохождения волны детонации, поперечный размер которого равен критическому для данного взрывчатого вещества диаметру, а угол при вершине выемки подобран с таким расчетом, что волна детонации подходит перпендикулярно к середине боковой поверхности выемки.A cumulative punch charge device containing a metal casing filled with explosive, an intermediate detonator mounted on the end wall of the casing, and a cumulative recess with a facing facing the apex of the detonator located on the opposite side of the casing, with an inert screen between the detonator and the apex of the recess material, which, when the detonator is triggered, is bent around by a detonation wave, preventing the passage of the latter directly to the top of the recess, which differs that the screen is located in the immediate vicinity of the detonator and forms a channel for the passage of the detonation wave with the end and side walls of the body, the transverse dimension of which is equal to the diameter critical for a given explosive, and the angle at the apex of the recess is selected so that the detonation wave fits perpendicular to middle of the side surface of the recess.
