Целью работы является постановка и решение задачи проектирования рационального конструктивно-технологического решения руля, отвечающего требованиям прочности, жесткости, аэроупругой устойчивости и минимума массы. Для решения поставленной задачи предложен алгоритм проектирования аэродинамического руля с использованием топологической и параметрической оптимизации. Определены основные параметры области проектирования и балансировочного носка, необходимые для топологической оптимизации. Для конечно-элементного анализа и топологической оптимизации использовался программный комплекс ANSYS Workbench. По результатам оптимизации проведена постобработка и предложено конструктивно-технологическое решение, объединяющее в себе силовые схемы с постоянной и переменной шириной балансировочного носка. Проведен анализ напряженно-деформированного состояния и установлено, что спроектированная конструкция отвечает требованиям прочности для заданного расчетного случая. Предложена схема решения задачи параметрической оптимизации руля по условию аэроупругой устойчивости. В рамках решения данной задачи проведено исследование флаттера с использованием многостепенной модели, позволяющей исследовать рулевые и корпусно-рулевые формы флаттера беспилотного летательного аппарата (БЛА), оснащенного аэродинамическими рулями. Получены результаты исследования флаттера для расчетного режима полета БЛА в виде зависимостей критической скорости и частоты флаттера от средней ширины балансировочного носка. Анализ данных зависимостей позволил определить оптимальные значения параметров балансировочного носка из условия минимума массы для двух вариантов рулей: с постоянной и переменной шириной балансировочного носка.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers a design process of an aerodynamic rudder, which structure comprises the skin of constant thickness, a load-bearing structure and a trimmed nose that plays the role of an anti-flutter balancer. The aim of the work is to set and solve the design problem of a rational structural and technological solution of the rudder that meets the requirements of strength, rigidity, aeroelastic stability and minimum mass. To solve this problem, a design algorithm for the rudder, using topological and parametric optimization, is proposed. The main parameters of the design area and the trimmed nose required for topological optimization are determined. The ANSYS Workbench software package was used for the finite element analysis and topological optimization. Based on the results of optimization, post-processing was carried out. A structural and technological solution, that combines structural layouts with constant and variable width of the trimmed nose, was proposed. An analysis of the stress-strain state was carried out, and it was found that the designed structure meets the strength requirements for the given design case. A scheme for solving the parametric optimization problem of the rudder under the condition of aeroelastic stability is proposed. Within the framework of solving this problem, a flutter study was conducted, using a multi-mode model, which makes it possible to study the rudder and body-rudder flutter forms of an unmanned aerial vehicle (UAV) equipped with aerodynamic rudders. The results of the flutter study for the design mode of the UAV flight are obtained in the form of dependencies of the critical flutter velocity and frequency on the average width of the trimmed nose. The analysis of these dependencies allowed us to derive the optimal values of the trimmed nose parameters from the minimum weight condition for two rudder configurations: with a constant and variable width of the trimmed nose.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аэродинамический руль</kwd><kwd>топологическая оптимизация</kwd><kwd>параметрическая оптимизация</kwd><kwd>жесткость</kwd><kwd>прочность</kwd><kwd>аэроупругая устойчивость</kwd><kwd>флаттер</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aerodynamic rudder</kwd><kwd>topological optimization</kwd><kwd>parametric optimization</kwd><kwd>rigidity</kwd><kwd>strength</kwd><kwd>aeroelastic stability</kwd><kwd>flutter</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">Новиков В.Н., Авхимович Б.М., Вейтин В.Е.
