Self-propulsion of a body with rigid surface and variable coefficient of lift in a perfect fluid

Abstract: Изучается двумерная задача о движении твердого тела в безграничном объеме идеальной жидкости, совершающей безвихревое движение и покоящейся на бесконечности. Тело снабжено гиростатом, а также ротором Флеттнера, благодаря которому на тело действует гироскопическая сила (эффект Магнуса). Угловые скорости вращения гиростата и ротора предполагаются известными функциями времени (управлениями). Уравнения движения представлены в виде уравнений Кирхгофа, и в случае кусочно-постоянных управлений указаны законы сохранен… Show more

“…Motion control by variable circulation. For the case where circulation is a piecewise constant function of time, this problem has been solved in [26]. In this case, preservation of first integrals of motion was used on the intervals of constant circulation.…”

“…The nonzero circulation results in the appearance of gyroscopic forces acting on the body [9], which change the dynamics of the system significantly. The controlled motion using an internal rotor changing the proper gyrostatic momentum of the system and using a Flettner rotor changing the circulation around the body is considered in [26]. In [32], analysis of the free motion of a hydrodynamically asymmetric body in an ideal fluid in the presence of circulation is performed and the controllability of the motion by changing the position of the center of mass of the system is proved.An essential part of the investigation of the controlled motion is the proof of the possibility of control.…”

“…Also in [40], analysis was made of the problem of compensation for the drift, arising due to circulation, using controls. The focus of [37] was on the problem of controlling the motion of a smooth body using the internal fly-wheel and the Flettner rotor creating variable circulation. The motion of the smooth body by means of oscillations of the rotor and by periodically changing circulation was studied in [10].…”
