Основным критерием для построения данной методики является минимальное время расчёта. Методика основывается на гипотезе локальности: аэродинамические характеристики каждого элемента поверхности рассчитываются независимо друг от друга. Предлагаемая методика представляет собой совокупность известных методов в рамках сверхзвукового обтекания тонкой пластины и гибкого механизма их применения с учётом кривизны поверхности летательного аппарата.</p></sec><sec><title>   Результаты</title><p>   Результаты. Проведена верификация предлагаемой методики на конусе, веретенообразном теле и прямом крыле с тонким профилем в сравнении с существующими методиками расчёта аэродинамики и численным моделированием. Продемонстрировано хорошее совпадение значений аэродинамических коэффициентов с результатами численного расчёта.</p><p>   Теоретическая и/или практическая значимость заключается в использовании рассматриваемой методики для предварительной оценки аэродинамики летательного аппарата на малых сверхзвуковых скоростях полёта с последующим их уточнением с помощью более точных методов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Aim</title><p>   Aim. Verification of local similarity method for calculating the aerodynamics of aircraft at low supersonic speeds.</p></sec><sec><title>   Methodology</title><p>   Methodology. The primary criterion for developing this method is minimal computation time. The method is based on the hypothesis of locality, i. e. aerodynamic characteristics of each surface element are calculated independently. The proposed technique for aerodynamics calculation is a combination of well-known methods widely-used in supersonic flow around a thin plate and a flexible mechanism for their application taking into account the curvature of the aircraft surface.</p></sec><sec><title>   Results</title><p>   Results. The technique proposed has been verified on s cone, a slender body of revolution and a thin straight wing. The verification has been carried by comparing with numerical simulation results and existing techniques of aerodynamics calculation. Good agreement between the aerodynamic coefficient values and the numerical calculation results was demonstrated.</p></sec><sec><title>   Research implications</title><p>   Research implications. The technique considered is supposed to be used to make preliminary assessment of the aerodynamics of an aircraft at low supersonic flight speeds, followed by their refinement using more accurate methods.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аэродинамика</kwd><kwd>аэродинамические характеристики</kwd><kwd>сверхзвуковое обтекание</kwd><kwd>тонкая пластина</kwd><kwd>локальный метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aerodynamics</kwd><kwd>aerodynamic characteristics</kwd><kwd>supersonic flow</kwd><kwd>thin plate</kwd><kwd>local method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была выполнена с использованием ресурсов ЦКП Сибирский Суперкомпьютерный Центр ИВМиМГ СО РАН и ЦКП «Механика».
