The title of this report is: “<strong>Calculations executed for the 2-bladed rotor of the VIRYA-1.8W windmill (lambda design = 6.25, wooden blades) used in combination with an 8-pole permanent magnet generator frame size 71 with a stator with no iron in the coils</strong>”. This is a rather simple rotor with water proof plywood blades coupled to each other by a thin stainless steel strip to make the rotor elastic. The blades have a constant cord and blade angle. I have used the Gö 711-12% airfoil which has a lower side which is flat for 97.5 % of the cord.</p><p>“The rotor is meant to be used with the radial flux PM-generator as described in . As this generator has almost no sticking torque, it can be used in combination with a rotor with a low starting torque coefficient and still have a low starting wind speed. As there are no iron losses, the generator will have a high peak efficiency . The advantage of using a standard motor housing is that the coils and the magnets are well protected against rain and that most components are mass produced and therefore rather cheap.</p><p>“This new report KD 664 contains detailed drawings of the rotor and the hub in the appendix. The VIRYA-1.8W makes use of the same head and tower as used for the VIRYA-1.8. Fotos of drawings of these head and tower are given in the manual part 2 of the VIRYA-1.81 which is given at the bottom of the menu KD-reports. To give an impression of the VIRYA-1.8 rotor drawings, I have added drawing 1801-01 as an attachment.</p><p>“Yours sincerely</p><p>“Adriaan Kragten”</p></div><br/><div>Posted in , </div></div><br/><div><div>Posted on by</div><div><p>Thanks to Ivan for these lovely pictures of the wind turbine he built and installed in the mountains of Croatia.

But I am still active and my website: will be maintained as long as possible. In the first half year of 2018 I have written five new free public KD-reports. Four of these reports give rotor calculations. At the menu “” on my website you find a short description of the content of each report. At the top of the menu “” there is the folder: “” and the folder “” which, I think, will be of great help for someone who wants to design a wind turbine.</p><p>Adriaan Kragten</p><p>Thanks Adriaan. This is a wonderful resource for students of wind turbine design. Here is a chart from KD35 showing the relationship between conversion “efficiency” and drag/lift ratio, over a range of tip speed ratios:</p></div><br/><div>Posted in </div></div></div><div><ul><li><p>If this blog helped you then make a donation</p></li><br/><br/><li><p>Buy a Tristar 45 controller</p><div>optional sensor</div></li><li><p>Choose a category and view posts</p>Choose a category and view posts</li><br/><li><p>Data from my smaller windmill</p></li><br/><br/><li><p>irish solar</p></li><br/><li><p>Recent Posts</p></li><br/><br/><li><p>Categories</p></li><br/><br/><li><p>Meta</p></li><br/><br/><li><div><p>From: Mike Allen<br/>Subject: Re: A Wind Turbine Recipe Book<br/>Date: 12 April 2013 10:53:18 BST<br/>To: jytte</p><p>I recieved the book yesterday and when it arrived I thought 'this isn't worth £12'.</p><p>But how wrong I was once I'd opened the envelope and settled down to read the contents with a cup of coffee. 3 hours later the coffee was stone cold and I was still reading the book.</p><p>Loads of info to be getting on with.</p><p>Thanks a lot.</p><p>Michael.</p></div></li></ul></div></div> | + | |typeproject=TUBerlin |
