Аэродинамические профили, оптимизированные под один конкретный режим, демонстрируют неоптимальные характеристики в других, что ограничивает общие летные возможности судна. Перспективным решением данной проблемы является использование адаптивного крыла, способного изменять свою форму в полете. В данной работе представлен метод упрощенной многокритериальной оптимизации профиля такого адаптивного крыла. Для преодоления вычислительной сложности классического подхода с построением фронта Парето, особенно при большом количестве режимов полета, многокритериальная задача была сведена к однокритериальной форме. Это достигнуто с помощью метода взвешенной суммы целевых функций, которые были нормализованы по эталонным (идеальным) значениям коэффициента лобового сопротивления. Расчет весовых коэффициентов осуществлен на основе физического параметра – числа Рейнольдса, что позволяет сфокусировать оптимизационный алгоритм AeroSandBox на наиболее важном, крейсерском режиме. Геометрия профиля параметризована методом класса-формы (CST), а для быстрых и точных аэродинамических расчетов использовался инструмент NeuralFoil на основе физически информированного машинного обучения. В работе решены две оптимизационные задачи: для двух и четырех режимов полета. Результаты двухточечной оптимизации качественно и количественно согласуются с данными, полученными независимо более сложными методами. Показано, что использование идеализированного механизма адаптации кривизны обеспечивает достижение компромиссным профилем 82,7–87,5% от аэродинамического качества эталонных профилей, оптимизированных для каждого режима в отдельности. Предложенный метод демонстрирует снижение вычислительных затрат при сохранении высокой эффективности проектных решений. </p></abstract><trans-abstract xml:lang="en"><p>Modern small unmanned aerial vehicles (UAVs) perform a wide range of missions, requiring high efficiency in various, often conflicting, flight conditions. Conventional airfoils, optimized for a single specific condition, exhibit suboptimal performance in others, limiting the overall flight capabilities of the vehicle. A promising solution to this problem is the use of a morphing wing, capable of changing its shape in flight. This paper presents a simplified method for the multi-objective optimization of an airfoil for such a morphing wing. To overcome the computational complexity of the classical Pareto front approach, especially with a large number of flight conditions, the multi-objective problem was reduced to a single-objective form. This was achieved using the weighted sum method, where the objective functions (drag coefficients for each flight condition) were normalized relative to their reference values. The weights were calculated based on a physical parameter – the Reynolds number – enabling the optimizer to prioritize the most important cruise regime. The airfoil geometry was parameterized using the Class-Shape Transformation (CST) method, and for fast and accurate aerodynamic calculations, the NeuralFoil tool, based on physics-informed machine learning, was used. The study solves two optimization problems: for two and four flight conditions. The results of the two-point optimization are in good qualitative and quantitative agreement with data obtained independently by more complex methods. Results demonstrate that employing an idealized curvature adaptation mechanism enables the compromise airfoil to achieve 82.7–87.5% of the aerodynamic efficiency of reference airfoils, each optimized for a single specific condition. The proposed method demonstrates a significant reduction in computational costs while maintaining high efficiency of the design solutions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>адаптивное крыло</kwd><kwd>механизация крыла</kwd><kwd>оптимизация профиля крыла</kwd><kwd>беспилотное воздушное судно</kwd></kwd-group><kwd-group xml:lang="en"><kwd>morphing wing</kwd><kwd>high-lift devices</kwd><kwd>airfoil optimization</kwd><kwd>unmanned aviation vehicle</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Barbarino S.
