Program package for the computer-aided aerodynamic design system for descent vehicles in planetary atmospheres

The mathematical support for the calculation of the aerodynamics and flight trajectory of descent vehicles (DVs) entering the Earth’s atmosphere from space is considered. The study of the aerodynamics of a segment- and cone-shaped DV is carried out under a wide range of atmospheric entry conditions. Comparison of the results of the calculations of aerodynamic characteristics of the “Phobos-Grunt” DV and of the data of wind tunnel tests of its models is presented.
