We study the system of a 2D rigid body moving in an unbounded volume of incompressible, vortex-free perfect fluid which is at rest at infinity. The body is equipped with a gyrostat and a so-called Flettner rotor . Due to the latter the body is subject to a lifting force (Magnus effect). The rotation...
