Sorry to correct you but the Magnus effect is the effect that a rotating cylinder in an airflow produces lift in the opposit direction to the airflow. This was used on experimental boats to utilize the wind. A Flettner rotor is a group of 4 to 6 vertically from a boat into the water hanging "wings" which rotate around a center and are (like a kind of helicopter) thereby able to pull the boat into any direction desired. Is used in harbour vehicles (and anywhere a boat which is able to go sideways is required.

Juli 1999 16:29 An: RCSE Betreff: [RCSE] Coanda effect The Coanda effect is the propensity for a flow to attach to a surface, like how water flowing over a rock clings to it even if the the rock face goes beyond the vertical! It can be improved by moving the surface instead, like a spinning football, which can deviate from a straight line to an amazing extent due to this helpful effect! I think it also was called the Magnus principle, which was used in some ships with Flettner rotors :-)! Which see! The name of a physical principle is almost always nationalistic, we for instance have no Centigrade, we have Celsius, after the Swede who invented the scale! In the Anglo-Saxon world the Swede was erased! Tord, Sweden -- If reply difficulties - use [EMAIL PROTECTED] Tord S.
