 MAGNUS TOW
Towed frame with rotor control.

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.
To observe the trawl nets a camera (b/w, colour or low light) is used, which can be turned 300 degrees in horizontal and vertical direction.
To get better video pictures in poor visibility conditions, on request two additional lights can be connected to the system. A digital depth meter is displayed on the screen.
