Each characteristic function of the shaped charge geometry can be considered a variational parameter in the Orlenko hydrodynamic model. Respectively, the author formulates the problem for determination of an unconditional extremum, as well as a subproblem for determination of a conditional extremum when an integrated condition is added</p>
