Numerical solution of non-steady problems of supersonic inflow of a binarymixture of a rarefied gas on a normally posed wall with mirror and diffusereflection laws is obtained on the basis of the kinetic Boltzmann equation forthe model of hard sphere molecules. For calculation of collision integrals weapply the projection method, developed by Tcheremissine for a one-component gasand generalized by the author for a binary gas mixture in the case ofcylindrical symmetry. We demonstrate a good qualitative agreement of ourresults with other authors for one-component gases.
