Аннотация:The paper is devoted to the further development of the numerical methods to solve model kinetic equations and their application to hypersonic rarefied gas flows. Firstly, we verify the accuracy of the approach
by comparing our results with the well resolved DMSC calculations for argon and nitrogen. Secondly,
computation of an external flow over a model winged re-entry vehicle with orbital free-stream velocity
and 100 km altitude is shown. Influence of the spatial mesh type is studied. Finally, scalability of the
implicit kinetic solver is demonstrated for up to 256 nodes.
