      Godunov method was used to develop a computational technique for gas flows through fixed lattice-type shields allowing severed, times altenuation of shock wave intensities. A model of "frozen" gas suspension (the lattice nodes are assumed to be fixed, gas/node heat exchange is neglected), the lattice volume content and perforation degree are Included. 1-D computation results are given for shock propagation through the duet medium, across the layer of meshes differing in boundary conditions and 2-D computation data on the attenuation of explosive effect on cylinder vessel walls where lattice- type shields are placed.
