RES - Ring Wing Turbine

The Secret of the Ring Wing unveiled!

The drawings show a circular shaped ring wing divided in 16 segments. On the left side, one segment is shown as an unwound wing with aerodynamic forces derived from the wind speed, the rotational speed and the conical angle of attack summing up to resulting inflow. (please see: #resα) The uplift force always being perpendicular to the resulting inflow points windward and in the direction of rotation. From the uplift force a tangential propulsion force and a thrust force opposite to the direction of wind can be derived. Looking at different sections of the ring wing on the right side, it becomes quite clear that the wind will overflow the ring wing in the blue plane, because the blue profile has less resistance than the red profile belonging to the red plane. Here the red profile would have to be overflowed effecting more resistance than the blue profile because it is not only larger in cross area but also is not appropriate for laminar flow. In the red plane, having an intersection with the focus of the ring wing uplift forces would eliminate each other when attacking at center. In the blue plain however, the blue profile offers minimum resistance for the incoming flow and uplift forces will be rotational effective because they attack with an offset to the center of the wheel. The grey profile shows the structural section of the ring wing parallel to the rotational axis of the turbine.
