Computational and theoretical investigation of Mars’s atmospheric impact on the descent module “Exomars-2018” under aerodynamic deceleration

Abstract

Methods for calculating the aerodynamic impact of the Martian atmosphere on the descent module “Exomars-2018” intended for solving the problem of heat protection of the descent module during aerodynamic deceleration are presented. The results of the investigation are also given. The flow field and radiative and convective heat exchange are calculated along the trajectory of the descent module until parachute system activation.
