### Re: Furling of a Horizontal Axis Wind Turbine

I am working on the designing of a furling mechanism for a horizontal axis wind turbine. Turbine diameter is 5.6 m. I did following calculation: Turbine thrust is 1.628 kN (using WT_perf) at 20 m/s wind speed (speed at which furling should start) Offset between generator and tower axes is 0.28 (5% o...

### Furling of a Horizontal Axis Wind Turbine

I am looking to design a Furling mechanism for a Horizontal Axis Wind Turbine. I am required to calculate: 1. horizontal oﬀset of turbine axis from the vertical yaw axis 2. tail surface area 3. The length of the boom 4. The weight of the tail is there any software which would be helpful for designin...

### Can HARP_Opt import Blade Geometry?

Is it possible that HARP_Opt do not calculate blade geometry itself (Chord and Twist distribution) but import from a file and do analysis?

### WT_Perf (wind velocity vs. Power)

I am using WT_Perf to analyze a small scale horizontal axis wind turbine. From WT_Perf we can get tables of Power vs. wind speed at different RPM. If I do not know the TSR and RPM of the rotor then is it possible that the software itself calculate RPM for different wind speed? If we give wind veloci...
