FIELD: test equipment, applicable for determination of the optical focal length of elongated shaped charges. ^ SUBSTANCE: the device has a plate with a chamfer and horizontal platforms, brackets for fastening of the elongated shaped charge positioned on the side of the chamfer. Lateral grooves are made on the plate chamfer between the horizontal plates, depth h of each groove corresponds to the value of the highest wall of the groove and is determined from relation where lk - the length of the generating line of the shaped charge cumulative groove; rho1.0 - the initial density of facing of the elongated shaped charge; rho2.0 - the plate density. ^ EFFECT: enhanced accuracy of measurement by standard tools of the depth of incision of the cumulative jet into the obstacle at a minimum quantity of tests. ^ 2 dwg |
