The problem of the infinite vortex tube structure dynamics in an ideal gas with an explosive external supply of energy near its axis solution is considered. It was found that, neglecting viscosity and heat conductivity, the tube collapses at an arbitrarily low power of energy release, while the decay time of the vortex decreases with increasing total power of energy release. A physical flow pattern that explains the discovered patterns is constructed. Analytical relations for the practical use of explosives in the destruction of large-diameter vortices are obtained. Estimates show that the proposed method is practically feasible.
