Its up!!
« on: March 24, 2008, 07:08:04 AM »
Well my mate Dave turned up with his trailer with the 38m (120 foot) telescope mast - only 3 sections out of the 6 of it loaded - and now I know what order to wind the winches to get the beastie up.


Our first trial is at about 9m (30') just to see how it goes. I'm impressed!!


15km/hr breeze (according to my weather station) and it immediately leap off at 8 amps so a very useful 200w into the pair of 150amp/hr truck batteries I'm using on my 24v system.


I don't have any image resizing software immediately to hand but this is the test system until I put a couple of fences across the paddock for guy anchors during the winter (the ground is too hard at present).


I'm impressed by the lack of noise - just a very faint hum.


Bugs discovered so far are:

  • a slight imbalance, not sure if its static balance (which I tried pretty hard to get right), blade tip tracking or something else

  • the angle of the tail need to be another 10 or 15 degrees - its at about 100 at present and the tail is not pulling it round into the wind very well.

  • I forgot to grease the yaw bearing on assembly so its not turning into wind at low wind speeds very well. That relates to the point above. I'd like a bit of PTFE sheet as a bearing on the pole as well as some gunge...

    Nothing's as easy as drilling a hole in the wrong place

     Nice set up! It seems weird to me seeing Summer when I still have a foot of snow in the back yard. Have fun with it.

    What are you on then?

    Most linux versions come with free editors in the bundle, I'm running ubuntu which came with GIMP , theres plenty for Mac's too.

    (PS-Christmas island? (ath.cx) :) )

      If you're running linux, then i imagine it came packaged with GIMP which will re-size  

    any graphics file. If it didn't then add GIMP. (it's also available for windows)

    OK - I admit it. I have all this software to hand but since I'm already putting all the pictures onto the my own website and I find the connection to the board somewhat flakey from here sometimes I just put in a link. That has the advantage of giving readers the opportunity to see the full 5megapixel images as ell as the scaled ones.


    Sitting here at work and now that I can see the wind speed etc at home I see I'm missing some good testing weather :-(

    Still waiting for a good strong wind (isn't it always the case?) but with a 30km/hr gust last night I saw 34amps and just starting to furl (tail angle down from 100 to about 80 degrees). With the fully charged batteries I have on there sitting at 28 volts with that much charge current, that corresponds to 950w so I'm a very happy camper:-)


    Still got to make the charge controller so I'll be making a start on it tonight I hope.
