Unmanned Aerial Vehicle (UAV) Turbine

Unmanned Aerial Vehicle (UAV) Turbine

One of the most significant features of the UAV Turbine is that its tethering system connects the airborne device to either two tracks, or else to one track and a ground anchor situated at the axis of rotation. Other airborne wind machines tether the airborne device with only a single cable. In this case, the airborne device is poorly positioned to make the transition from its upwind arc to its downwind arc, and vice versa. Of course, tethering with two cables isn’t very appealing. But one of these cables can be eliminated if an oblong track is used. For more on this, see Direct Drive Linear Turbine With Yawing Oblong Track.

Using small, light-weight tubes that are shaped like a symmetrical airfoil to tether the airborne device allows them to make a small contribution to output power. Otherwise the only contribution they make is drag.

The UAV Turbine can use kites instead of airplanes. Or it can use floating devices, such as the airfoils described in the Helium VAWT post.
