Для тела с большим моментом инерции получены автоколебания с амплитудой около 10 град. Впервые обнаружен феномен вырождения автоколебаний для тела с меньшим моментом инерции. Предпринята попытка смоделировать феномен при помощи обыкновенного линейного дифференциального уравнения первого порядка.</p></abstract><trans-abstract xml:lang="en"><p>Tests of a conical-spherical body in a supersonic wind tunnel were carried out on a free oscillation installation along the pitch angle at a Mach number M = 1.75 and two moments of inertia of the body relative to the axis of rotation. For a body with a large moment of inertia, self-oscillations with the amplitude of ca. 10 deg were obtained. For the first time, the phenomenon of degeneration of self-oscillations for a body with a smaller moment of inertia has been discovered. An attempt was made to model the phenomenon using an ordinary linear differential equation of the first order</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коническо-сферическое тело</kwd><kwd>аэродинамическое демпфирование</kwd><kwd>самовозбуждающиеся колебания</kwd><kwd>автоколебания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>conical-spherical body</kwd><kwd>aerodynamic damping</kwd><kwd>self-excited oscillations</kwd><kwd>self-oscillations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках Программы фундаментальных научных исследований государственных академий наук на 2021–2023 годы (проект FWNE-2021-0012).
