Helical `Wind Wandler' Turbine
« on: August 10, 2005, 05:24:19 AM »
Hi all, this is my second time posting this, I don't know why my first post didn't work. Anyway, I came accross this site on the web while looking for helical designs for a VAWT. I came accross this helical HAWT.

The claims they are making:


Herr Josef explained that they are 53% efficient, as opposed to 46% for conventional bladed turbines, and the theoretical maximum efficiency that can be attained is 59%.


Output at 14m/s is about 1 kW. The disk armature generator is rated at 3.5kW and, unlike bladed turbines, they do not have to be stopped in high winds. Rotation speed at 24m/s wind is 1,400 rpm, but remains the same at 30m/s because surplus high speed air then tends to spill round the rotating turbine. The turbines turn naturally into the wind.


Is this for real? Seems like it would actually work, but I don't know about the efficiency claims...


I look forward to the comments from the experts....


Heres a pic:
