If I want to make a 0.5m blade, what would the table be like (r and L)?

hi green engineer, thanks for that good work. im building a wind turbine and i used your excel file to calculate. i cut one of blades. but my material of pvc pipe is too weak. i will buy thicker one. my question is is there anyone who used that calculation. does it work well?
2. question.
i live in apartment, i will build it on roof. maybe it will make some sound,noisy :S
can you give a suggestion should i build vertical or horizontal wind turbine,? can they produce same power with same wind?

Perfect video.. Gonna start tomorrow morning! Thx!!!!

Made a set last night - unloaded they were frightening. Gonna add more blades and up the torque, and use an alternator. The blades are a brilliant design! Found a nice flexible base PVC tube - and will monitor over time before they get brittle.

AHHHHHHHHHHHHH!!! MATH!!! MAKE IT STOP!!!

absolutely terrible music

The vid is way too fast for dummies ;) Do you have a good link for pdf etc?
-
too technical.
Look for a link to my website on my main page Try this link, scroll down a ways and you should see a document related to blade design. Your correct it is really to fast to get much out of it, but I thought it was at least a way to provide an overview that was not boring.

When I did this, I pretty much came up with the same equations, but I didn't bother with angle of attack. (I just figured loaded it will run a little below it's target TSR.)
I think you made a mistake converting angles to distance around the tube. It should be angle (rads) * tube radius. I think you might have used tube diameter.
At the hub center it should be close to 90 degrees, not 180.

There are some mistakes in the Video which were brought to my attention by some other users. The correct results can be found by following the link in my profile at the small wind turbine collaborative design site

This video didn't make it clear that you planned to put a skin across the open side of the tube, like the web page shows. Most people just use the open tube. My comments about your calculations are not valid for your configuration.

Good point, there is no skin shown in the video, I have been negligent on my testing and really have not confirmed which works best.

Um . . . . I am not smart enough to answer that. . . my guess is no
