Peculiarities of flow and heat transfer in the base region of generic model of martian descent vehicle

Some results concerning experimental and numerical investigations of Generic model of Martian descent vehicle (TC3 configuration) are presented. These investigations include determination of heat flux and pressure on the all model surfaces at different angles of attack. Experiments were carried out in TsAGI's wind tunnels UT-1 in air and in IT-2 in carbon dioxide. With the help of total pressure measurements, flow in the model base region has been diagnosed at laminar and turbulent cases. The study is focused on heating of the base surface
