Work is devoted to the solution of the one-dimensional equation of a hydraulic gas dynamics for the coaxial device - magneto plasma accelerator by means of Lax-Wendroff modified algorithm with an optimum choice of parameter of regularization – artificial viscosity. Replacement of the differential equations in private derivatives is made by final differences. Optimum parameter of regularization – artificial viscosity in the environment of MathCAD is added, using the exact known decision – a task Soda. The developed algorithm of calculation of thermodynamic parameters in a braking point is approved. On the basis of the offered algorithm in the environment of MathCAD thermodynamic parameters of a shock wave in front of the plasma piston are calculated at its departure from the coaxial magneto plasma accelerator. When modeling overwhelming unstable high-frequency fluctuations that allows to narrow area of heterogeneity are considered and to allocate only smooth decisions. Results of calculation of gas dynamic parameters in a point of braking coincide with literary data.
