| Abstract: | The effect of technological errors on the formation and displacement of components of a shaped-charge jet is studied numerically.
The linear character of the dependence of the radial center-of-mass velocity of the transverse cross section of a linear on
the magnitude of the variation in the wall thickness of shells and a layer of an explosive substance, and the variation in
its charge along the circumferential coordinate is clarified. Computations have shown that, for a shaped-charge jet, the magnitude
of the radial velocity can be considerably larger compared to the entire liner. This is due to a conversion of only a part
of the linear material to the jet, with large values of the radial velocity. The different values of the radial velocity along
the liner length lead to distortion of the jet shape, and, hence, to a decrease in the effectiveness of its action. Estimation
of the degree of influence of each technological error on the curving of a shaped-charge jet makes it possible to give concrete
recommendations concerning the increase in the precision of treatment and assembling of the corresponding members of an explosive
system.
