In non-stationary problems of flows, for example problem of shock wave diffraction on a flying body, the impulse of appearing drag force generates non-stationary forward and rotary movement of the body. The describing mathematical model is nonlinear not only with respect to coefficients of system of the equations, but also in the sense of dependence of the system of equations and boundary conditions from integral characteristics of the decision (drag force and its moment relative to the center of mass of the body). The purpose of this work is realization of computing aspects of numerical simulation of such problems by modern numerical algorithms on the example of model problem of shock wave diffraction on sphere in the shock tube. The problem was numerically simulated on the basis of the difference scheme of second order accuracy [1,2]. The 3-D structured grids construction was performed by algorithm based on the Poisson equations decision [5,6].
