The current paper contains the elliptic cone waverider and inclined cone waverider aerody-namics calculations results. The comparison between the numerical and experimental data was performed for the wide range of the angles of attack and sleep angles. All results was ob-tained by the UST3D code using different Riemann solvers within the framework of the splitting method. The acceptable agreement between the present results, the thin-layer Na-vier-Stokes and also parabolized Navier-Stokes data was demonstrated.

Keywords: finite volume method, splitting methods, Riemann solvers, waveriders

Численное моделирование аэродинамики волнолетов построенных на скачках уплотнения различной формы

В рамках настоящей работы представлены результаты систематических расчетов аэродинамических характеристик высокоскоростных летательных аппаратов – волнолетов, построенных на ударных волнах, образующихся при обтекании эллиптического или наклонного кругового конуса. Выполнено сравнение результатов численного моделирования с экспериментальными данными, полученными для различных углов атаки и скольжения. Продемонстрированы особенности совместной реализации метода расщепления по физическим процессам и одного из вариантов AUSM схемы. Проведено сравнение результатов расчетного исследования, осуществленного с использованием компьютерного кода UST3D и его модификации, со сторонними расчетными данными по аэродинамике различных конфигураций волнолетов, полученных с применением структурированных сеток, уравнений Навье-Стокса в приближении тонкого слоя, а также
параболизованных уравнений Навье-Стокса.

Ключевые слова: метод контрольного объема, расщепление по физическим процессам, распад произвольного разрыва, аэродинамика волнолетов
