  The statement of problem is motivated by the idea of modeling the classical
turbulence with a set of chaotic quantized vortex filaments in superfluids.
Among various arguments supporting the idea of quasi-classic behavior of
quantum turbulence, the strongest, probably, is the $k$ dependence of the
spectra of energy, $E(k)\propto k^{-5/3}$ obtained in numerical simulations and
experiments. At the same time the mechanism of classical vs quantum turbulence
(QT) is not clarified and the source of the $k^{-5/3}$ dependence is unclear.
In this work we concentrated on the nonuniform vortex vortex bundles. This
choice is related to actively discussed question concerning a role of collapses
in the vortex dynamics in formation of turbulent spectra. We demonstrate that
the nonuniform vortex vortex bundles, which appear in result of nonlinear
vortex dynamics generates the energy spectrum, which close to the Kolmogorov
dependence $\propto k^{-5/3}$.
