Abstract: The new version of a method of the characteristics with a floating grid for the solution the nonstationary gas-dynamic tasks is submitted in this paper. In these tasks the most precise definition are required for the forms and phases of a development of wave processes in extended channels. The calculations of dynamic resonance supercharge in the internal combustion engines and the wave interchangers of pressure are the tasks of this profile. The method allows to build-up of a grid of the characteristics only of two sets, but thus the registration of dissipative phenomena – friction and heat transfere with walls of the channel is taken into account. The example of calculation of dynamic supercharge of a tractor drive is adduced.
