Hello Everyone,
Just got back from a trip to Tassie and had to show you this, Tasmania Hydro's Woolnorth facility up close,
If you ever go to Tasmania then buy a tour of this place its amazing.
60mt to hub and 100mt to top of blade ark, 66mt blade diameter and about 260kph tip speed all generating 1.75mw from a 57tonne nacelle.
its impossible to describe what it was like standing right under one of these in a 28knot wind.

Hope you dont mind but I resized those pictures down a little.

Thats an impressive wind farm, and looks like its working hard by the flex in those blades.

So did you take out your tape and measure the blades?

Are my eyes deceiving me?

Is it camera angle? I've noticed this before on other pics of wind farms, The prop axis appears to be angled upwards about 3 degrees. If this is so, Why?

Great pics sangeff. Thanks.

was working fine... til the smoke got out.

It looks like they are angled and if so it would be to keep the blades away from the tower when flexing. I will go look at the turbines at one of the wind farms nearest me and try and take pics. The wife will love me for wanting to stop for pics on the way to the hospital when we get the call that we have a new grandbaby.

They did tell me why they are angled, but in the excitement I forgot.
Those blades are about 30mt long but I didnt take a tape with me, they are at least 1800mm at the widest point, I am 6 ft tall and the blade was only a few inches of the ground.
Vestas have a pretty good web site and these are the smallest turbines on the site, The new ones are on an 80 mt tower, these arent commissioned yet and this pic is from a few kilometers away.
