      The unsteady process of loading a blunt-nosed cone flying at a supersonic speed by a bow shock wave reflected from a flat screen is studied. The numerical simulation of the problem is performed using the model of an inviscid non-heat-conducting gas. Three-dimensional nonstationary Eulerian equations are integrated with Godunov’s difference scheme. The interaction of the reflected bow shock wave with the cone and screen surfaces is studied. Numerical results are illustrated by figures in the paper.
