Aerodynamic design of a descent vehicle in the Martian atmosphere under the exomars project

Abstract: The paper considers mathematical support for calculation of the aerodynamics and flight trajec tory of descent vehicles (DV) during entry into the Martian atmosphere. The study of aerodynamics of a seg mental and conical DV is given under various reentry conditions. The paper presents comparison of compu tational results of the aerodynamic properties of the DV of the ExoMars project with wind tunnel test data of DV models.

“…Среди множества численных исследований обтекания спускаемых аппаратов выделим работы, посвященные изучению обтекания аппаратов, предназначенных для спуска в марсианской атмосфере, в частности изучению аэродинамики десантного модуля, имеющего форму, совпадающую с рассматриваемой в данной статье. В работе [Golomazov et al, 2014] представлены результаты численных расчетов зависимости аэродинамических характеристик десантного модуля от угла атаки, полученные с учетом физико-химических процессов как на основе модели Эйлера невязкого газа, так и посредством интегрирования осредненных по Рейнольдсу уравнений Навье -Стокса. Работа [Finchenko et al, 2015] посвящена численному изучению аэротермодинамики десантного модуля на этапе торможения с применением модели конвективно-лучистого теплового потока к поверхности аппарата.…”

“…Moreover, it has professional toolboxes that have been rigorously tested to facilitate the efficient development of the code Lift and drag depend on the shape of the landing vehicle, the angle of attack, the velocity and the atmospheric characteristics of the planet. The graphs that show the variation of the lift and drag coefficients depending on the angle of attack and the velocity of the body [2,15] for Mars were digitalized using the online software WebPlotDigitizer (Version 4.2) [16] and the data obtained were implemented in the code. For Earth calculations, however, there was no available data about the lift and drag coefficients.…”
