The Radiative Gas Dynamics of Spacecraft in the Martian Atmosphere
Surzhikov, S. T.
The problems of the radiative gas dynamics of the Martian space vehicles MSRO, Pathfinder, and Exomars-2016 are solved using the author's custom NERAT-2D radiative-gasdynamic code. The cause of considerable heating of the rear surface of the spacecraft by heat radiation in the Martian atmosphere is studied. Calculation studies of the spectral comp…
Gas Dynamic Models of the Interaction between the Solar Wind and Cometary Atmospheres
Baranov, V. B.
Gas dynamic models of the interaction between the solar wind and cometary atmospheres are considered. Interest in the development of such models arose sharply after the beginning of the investigations of comets with the use of spacecraft launched at distances close to their surfaces. The instruments on this spacecraft gave the possibility to inves…
Numerical Analysis of Shock Layer Ionization during the Entry of the Schiaparelli Spacecraft into the Martian Atmosphere
Surzhikov, S. T.
The paper presents a numerical analysis of aerophysical nonequilibrium processes occurring near the surface of the Schiaparelli entry vehicle in the region of hypersonic flight in the dense Martian atmosphere. The two-dimensional model realized is based on the system of self-consistent equations of nonequilibrium physical and chemical mechanics of…
Three-dimensional magnetohydrodynamic model of the interaction between the solar wind and cometary atmospheres
Baranov, V. B.; Alexashov, D. B.; Lebedev, M. G.
A magnetohydrodynamic (MHD) model of the interaction between the solar wind and an expanding gas flow issuing from a comet nucleus is presented. The processes of photoionization of the neutral component of the comet matter and the resonance charge exchange between charged and neutral particles are taken into account, together with the interplaneta…
