Это достигается за счет выбора оптимальных углов поворота вектора суммарной тяги электроконвертоплана. В предлагаемом подходе балансировочный угол поворота винтомоторной группы является переменным в зависимости от аэродинамических характеристик электроконвертоплана, его винтомоторной группы. Поскольку винтомоторная группа оснащена приводами для ее поворота, то такой подход легко реализуется штатными средствами электроконвертоплана. Поворот вектора суммарной тяги, с одной стороны, приводит к увеличению эффективного значения аэродинамического коэффициента подъемной силой, а с другой стороны, сопровождается уменьшением проекции вектора суммарной тяги на вектор скорости полета, изменением лобового сопротивления, мощности, необходимой для создания тяги винтомоторной группы. Это обстоятельство и обуславливает необходимость решения задачи оптимизации с целью увеличения продолжительности или дальности полета на крейсерском режиме полета электроконвертоплана. В работе приводится методика расчета оптимальных углов поворота вектора суммарной тяги на основании уравнений установившегося движения электроконвертоплана на режиме крейсерского полета; выражения для суммарной мощности, необходимой для вращения винтов винтомоторной группы. Получены аналитические зависимости для оптимальных углов поворота вектора суммарной тяги в зависимости от соотношения площади крыла к суммарной ометаемой площади винтов винтомоторной группы и аэродинамического качества электроконвертоплана.</p></abstract><trans-abstract xml:lang="en"><p>The paper examined the possibility of improving the energy efficient performance of an electric tiltrotor with a lift-propulsion propeller group for a steady flight mode by reducing the energy consumption of the propeller group per unit of time or per unit of the path traveled by the electric tiltrotor. This is achieved by selecting the optimal tilting angles of the electric tiltrotor total thrust vector. In the proposed approach, the trimming tilting angle of the propeller group is variable, depending on the aerodynamic characteristics of the electric tiltrotor, its propeller group. Since the propeller group is equipped with the drives for tilting them, this approach is easily implemented by the conventional facilities of the electric tiltrotor. The tilting of the total thrust vector, on the one hand, leads to an increase in the effective value of the aerodynamic lift coefficient and, on the other hand, it is accompanied by a decrease in the projection of the total thrust vector on the flight speed vector, a change in the drag and power required to create the thrust of the propeller group. This circumstance makes it necessary to solve the optimization problem in order to increase the maximum endurance and long-range capabilities in the cruise mode of the electric tiltrotor flight. The paper presents a method for calculating the optimal tilting angles of the total thrust vector based on the equations of steady motion of the electric tiltrotor in the cruise flight mode, the expression for the total power required for the rotation of the propellers of the propeller group. The analytical dependences for the optimal tilting angles of the total thrust vector are obtained depending on the ratio of the wing area to the total propeller-disk area of the propeller group and the aerodynamic quality of the electric tiltrotor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электроконвертоплан</kwd><kwd>винтомоторная группа</kwd><kwd>угол поворота</kwd><kwd>оптимизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electric tiltrotor</kwd><kwd>propeller group</kwd><kwd>tilting angle</kwd><kwd>optimization</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">Kim H.D., Perry A.T., Ansell Ph.J.
