SINOPSIS

The investigation of the influence of boundary conditions of bodies in a flow is one of the most important problems in aerodynamics. This problem is especially important when aircraft move at a high altitude, i.e., at the regimes described by the molecular distribution function. This is an orbital flight of space vehicles, and a motion of aerospace systems in the upper atmosphere. Models of flows of molecules with different potentials of interaction are proposed in this paper. The boundary conditions are approximated on a wide range of regimes. The results of the calculation of aerodynamic characteristics of an airspace vehicle in the transitional regime are presented.
