Процесс проектирования магистрального воздушного судна (ВС), в частности на этапе предварительного проектирования, предполагает сравнение и анализ большого количества проектных альтернатив при заданных критериях эффективности. При этом решается задача выбора состава рациональных проектно-конструкторских параметров, что является актуальной проблемой этапа предварительного проектирования ВС. Метод. Разработанный метод, позволяет определить вектор параметров, обеспечивающий рациональные характеристики при заданном критерии эффективности. В связи с чем, предлагаем ввести глобальный критерий эффективности — взлетная масса ВС, а частными критериями выступают аэродинамическое качество на крейсерском режиме полета и величина топливной эффективности. Результат. В такой постановке задачи проектирования приходится решать ряд взаимосвязанных задач, причем, одни являются формализованными, а для других пока не существует математического аппарата и ПО, позволяющего автоматизировать процесс. Отличительной особенностью предлагаемого подхода к поиску рационального проектного решения является применение методов статистического анализа в сочетании с методами высокоточного математического моделирования, программно-реализованные в единой информационной среде с применением языков Фортран V и C++. Вывод. Предлагаемый метод выбора состава рациональных проектноконструкторских параметров позволяет на ранних стадиях и этапах проектирования магистрального ВС, сформировать облик и обеспечить заданные характеристики для его составных элементов.</p></abstract><trans-abstract xml:lang="en"><p>Objective. The process of designing a long-range aircraft, in particular at the preliminary design stage, involves comparing and analyzing a large number of design alternatives with specified performance criteria. At the same time, the problem of choosing the composition of rational design parameters is solved, which is an actual problem of the preliminary design stage of a long-range aircraft. Methods. The developed method allows determining the vector of parameters that provides rational characteristics for a given efficiency criterion. In this regard, the authors propose to introduce a global efficiency criterion - the takeoff weight of the long-range aircraft, and the specific criteria are the aerodynamic quality in cruise and the value of fuel efficiency. Results. In this formulation of the design problem, it is necessary to solve several interrelated problems, some of which are formalized, while others do not yet have a mathematical construct and software that allows automating the process. A distinctive feature of the proposed approach to finding a rational design solution is the use of statistical analysis methods in combination with methods of high-precision mathematical modeling, software-implemented in a single information environment using the Fortran V and C++ languages. Conclusion. The proposed method for selecting the composition of rational design parameters allows forming the appearance and providing the specified characteristics for its component elements at the early stages and stages of designing the long-range aircraft.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воздушное судно</kwd><kwd>выбор параметров</kwd><kwd>облик воздушного судна</kwd><kwd>параметрический синтез</kwd><kwd>вектор параметров</kwd><kwd>многопараметрический подход</kwd><kwd>концептуальная модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aircraft</kwd><kwd>parameter selection</kwd><kwd>aircraft appearance</kwd><kwd>parametric synthesis</kwd><kwd>parameter vector</kwd><kwd>multiparametric approach</kwd><kwd>conceptual model</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках стипендии Президента РФ № СП-3606.2018.1 от 29.12.2017 г., для молодых ученых и аспирантов на выполнение научного исследования по теме «Методология автоматизированного синтеза проектных и конструкторских параметров транспортной техники нового поколения».</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the scholarship of the President of the Russian Federation No. SP-3606.2018.1 dated December 29, 2017, for young scientists and graduate students to carry out scientific research on the topic "Methodology of automated synthesis of design and design parameters of new generation transport equipment."</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Федеральная целевая программа «Развитие авиационной промышленности на 2013-2025 годы».
