Free and controlled motion of a body with a moving internal mass through a fluid in the presence of circulation around the body
Authors:E V Vetchanin  A A Kilin
Abstract:The free and controlled motion of an arbitrary two-dimensional body with a moving internal mass and constant circulation around the body in an ideal fluid is studied. Bifurcation analysis of the free motion is performed (under the condition of a fixed internal mass). It is shown that the body can be moved to a given point by varying the position of the internal mass. Some problems related to the presence of a nonzero drift of the body with a fixed internal mass are noted.
