Abstract: Aim. The aim of this work was to develop an algorithm for determining the density of incident mass, momentum and energy flows on a body of complex shape, flown around by a highly rarefied gas.Methodology. The work uses methods of the molecular-kinetic theory of gases, aimed at determining the macroscopic characteristics of a rarefied gas flow. The work is based on the numerical solution of integrals of the Maxwell distribution function.Results. An algorithm has been developed and tested on a model simulating a device (solar battery panel, antenna, etc.) installed on the surface of a spacecraft body.Research implications. The developed algorithm can be used in problems related to determining the distribution of mass, momentum and energy flow densities over the surface of objects flown around by a highly rarefied gas medium, and in problems related to determining the characteristics of a spacecraft's own external atmosphere.
