摘要

For increasing the ultimate elongation of cumulative metal jets, the possibility of heating of them at the stage of their inertial stretching in the movement in the space of a tube, forming a thermal radiation flow converging to the axis of the tube, was analyzed. A source of thermal radiation was a chemical compound reacting in the regime of self-propagating high-temperature synthesis. The investigations were performed on the basis of the obtained analytical solution of the one-dimensional axisymmetric problem on the nonstationary heat conduction in an evenly elongating cylindrical rod subjected to radiant heating.
