I NEED HELP ABOUTH MY BLADE

[tico]

I need a computer to 1m blades.I have built a compact generator with 48 magnets
I am from romania and please excuse my English
 Is about 150 mm diameter generator and I need a sketch or account for 1m blades do not know other only metric measures

tico;

This is as good an online reference as any for blade carving. By a master of the craft and a pioneer of home made turbines:

It is in English but the pictures should be worth the time to look at.

Welcome to the forum and good luck on your project.

this is the first blade model that i have built
 for me I need paddle diameter narrower and smaller in thickness should be like starting from 40mm

Hi,
I'm comfortable with metric - can you give me more information?
How fast do you want your generator to be turned?

The "four foot diameter" plans on the Hugh Piggott website have a 1.2 meter diameter.  An excellent starting point.

If you want to try scaling that down to 1.0 meter diameter, then scale all of the others by the same factor.

abouth 150 rot
blade must be like this

[tico]

abouth 150 rpm give me 12 volt

this is my rotor and you can see the scale

The blades in your picture are between 6 to 8 feet in diameter, or between 1.8m to 2m.  They look a lot like the Hugh Piggot design, but you want a size smaller than that.  2 meters is quite large for the size of disks you show in your second picture. 
Assuming you have completed that generator now with several magnets and coils, then a rotor about 1 meter in diameter may be about the right size.
So I agree you are on the right track.

Try looking through the Hugh Piggott website more:

and look especially at these pages:

You can try your own calculations with his spreadsheet:

My generator is calculated at 200 W
 I searched everywhere but information abouth human mistake guided me
 the principles you learn to be better can make the peaple better
 so I try to generate a positive effect on all who know me
2 generator is working and will post pictures will be finished after

I wish you success, and we look forward to seeing it progress.
