В литературе это решение известно как классический вариант механизации крыла. В настоящей работе представлены результаты численных и экспериментальных исследований некоторых решений, предназначенных для повышения эффективности классического варианта механизации. Концепция механизации задней кромки, именуемая «Адаптивный закрылок», рассмотрена как способ улучшения аэродинамических характеристик самолета на режимах взлета и посадки. Интеграция отклоняемого вниз спойлера с выдвижением закрылка позволяет повысить максимальный угол отклонения закрылка в посадочной конфигурации и значение коэффициента подъемной силы на линейном участке, соответственно. Во взлетной конфигурации увеличение аэродинамического качества возможно за счет уменьшения отклонения адаптивного закрылка при сохранении подъемной силы крыла. Для эффективной защиты передней кромки крыла от раннего отрыва потока на больших углах атаки использован щелевой щиток Крюгера удобообтекаемой геометрии. Предварительное проектирование усовершенствованного варианта механизации включало определение аэродинамической формы и положения механизации на режимах взлета и посадки. Аэродинамический анализ характеристик выполнен с использованием двумерных методов расчета высоконесущей системы в рамках осредненных по Рейнольдсу уравнений Навье-Стокса. Проведено сравнение результатов проектирования классического и усовершенствованного вариантов механизации, показавшее преимущество последнего в аэродинамических характеристиках. Результаты весовых испытаний модели самолета с адаптивной механизацией задней кромки крыла в аэродинамической трубе подтвердили ее эффективность.</p></abstract><trans-abstract xml:lang="en"><p>The use of Fowler flaps and slotted slats in sweptwing aircraft is the standard solution to increase wing lift at take off and landing. In the literature this solution is known as a classical option of high-lift system of commercial subsonic aircraft. The results of numerical and experimental studies of some solutions intended to increase the efficiency of classical high-lift devices are presented. The concept of the trailing-edge devices called "the adaptive flap" is considered as a way to improve flap efficiency. The adaptive concept is characterized by the integration of spoiler downward deflection to the Fowler flap function. Integration of the spoiler with a movable flap provided an increase of lift in the linear region due to flaps deflected to a higher angle. The steeper upwash angle at a leading-edge device may be the reason of an early stall of the main wing. To protect the leading edge a slotted Kruger flap with streamline form has been used. Preliminary design of classical and improved high-lift systems included the determination of aerodynamic shapes and the optimized position for the high-lift devices. Aerodynamic analysis and design were carried out using 2D RANS Navier-Stokes method. A comparison of computed results has shown visible aerodynamic advantages of an improved high-lift system for maximum lift coefficient and refining the behavior of stall characteristics at high angles of attack. The results of wind tunnel tests of aircraft model with adaptive flap showed its effectiveness.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>механизация крыла</kwd><kwd>адаптивный закрылок</kwd><kwd>щиток Крюгера</kwd><kwd>аэродинамическое проектирование</kwd><kwd>экспериментальные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-lift devices</kwd><kwd>adaptive flap</kwd><kwd>Kruger device</kwd><kwd>aerodynamic design experimental studies</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">Rudolph P.K.C.
