Показано, что резонансное взаимодействие тонкого стержня со сдвиговым течением «мелкой воды» приводит к развитию ветровой неустойчивости. Получены дисперсионное уравнение и инкремент неустойчивости. С уменьшением «скорости звука» происходит уменьшение диапазона длин волн, в котором существует неустойчивость. Приведены численные оценки частоты и инкремента волн изгиба для различных параметров течения.This is a research of the resonance interaction of a thin rod with shear flow «small water» section which brings to development of wind instability. The dispersion equation and increment of instability is given here. Wave band with instability is being diminished by diminution of acoustic speed. The authors also present the numeric evaluations of frequency and increment of flexural waves for different parameters of flow.
