The towed frame, manufactured completely
out of stainless steel is propelled by rotating cylinders, which
work with the "Magnus"- effect.
The rotation of the cylinders injects
a "potential turbulence" which, overlaid by a laminar current, causes a
pressure force. This pressure force (similar the principle of a wing) is
perpendicular to the laminar current and is related to the rotation speed
of the rotor. This effect in combination with the special arrangement of
the rotors is used to control the towed frame. In this case two vertical
rotors and a horizontal one are used in order to achieve an ideal steering
of the towed system. |
