state of the shaft after towercrash

redressed shaft,bearings and bearinghousing

The normal and thrustbearing(need a spacer between),upper side of the shaft

The plumbingpart that was the nearly exact fit for the bearings

connection between shaft and threaded rod of the rotor

8kg weight on each foot

flying!

Pitchoune asks herself what for the hell she has to lay down in this place

my place

even the guys up there get curious

How did you make the blades? I tried to look at your previous torkmaster post from June, but the pictures don't show up.

Stonebrain · « **Reply #2 on:** July 26, 2006, 04:37:35 PM »

That's because I deleted some of my files.

I shouldn't have done it.

I'm very sorry.

Will try to get them back,if that works.

we need video !!

that is such a unique shape , it would be great to see it spin !!!

The pictures in

http://www.fieldlines.com/story/2006/6/14/212552/504

are back again.

I hope I can bring back the pictures from my very first story

too but I don't know if there is some maximum diskspace for the files

hope you like it

cheers,

Here is a video:

I couldn't get uploaded more but will try it later

cheers,

it looks good stonebrain.

it looks as though it was just in a light breese.

i'm shure you realise that this shape could be made very large.

is would be simple if you expand it at a constant rate , as in the the nature of what is known in geometry as the "golden section" (like a sea shell).

Slingshot · « **Reply #8 on:** July 27, 2006, 08:22:11 AM »

That's fantastic. How did you come up with the design? Is it a scaled model of something already working, or is it the first?

electrondady1 · « **Reply #9 on:** July 27, 2006, 08:50:09 AM »

i just want to make one suggestion. paint the insides of the vanes a different color than the outsides . that will really show it off.

the file upload area for each user is quite large don't worry about maxing it out.

nanotech · « **Reply #11 on:** July 27, 2006, 12:29:51 PM »

If anyone needs any upload space, please email me them and I can host up to 100MB.

Stonebrain · « **Reply #12 on:** July 27, 2006, 02:32:34 PM »

Thanks kurt,

my pics are back,

but I don't get avi files uploaded anymore.

Maybe to big?

cheers,

Wind was a bit above 10km/h

Ihave another avi with nearly no wind,turning very slow,

but I can't get it uploaded.

Fancy colors would be nice.

cheers,

Nice job Stonebrain

Looks like your efforts are paying off.

What do you think about moulding off the inner sections or is having them open part of your plan?

Pitchoune seems confident with your work my dogs a nervous wreck.

Stonebrain · « **Reply #15 on:** July 27, 2006, 03:25:48 PM »

Look here how it was revealed to me:

http://www.fieldlines.com/story/2006/4/7/13354/21751

all pics are back.

Basicly it is to a savonius wat a H-rotor is to a darius:

a savonius without top-bearing.

Hope it will perform like a savonius.

cheers,

stonebrain

Stonebrain · « **Reply #16 on:** July 27, 2006, 03:48:43 PM »

What's happening in the innerpart is just guessing.

My idea is to keepit open to have a "crossflow" effect.

Just like any savonius.

my rule is to interfere with airflow only when you can

expect positive drag or lift.

What I should do is to build some rotors based

on the same principle but with some parameters of the

geometry varying and mesure performance.A hugh program.

I'm on my way for the dynamometer that goes with my

setup.I have some ideas about it and I'm sure

it will be loads of fun.

A shame I'm so slow.

cheers,

stonebrain

Stonebrain i didnt mean that you were on a slow pace.It was more directed at the dogs confidence in your abilities, not afraid of things going airborn like my mut.

Evening Stonebrain

Been watching this sense your first post about it.

NICE.

Think I will try one just for fun.To poor to build a big one SO a charger for some AA batt's for path lighting maybe.

Once again NICE.

later

Hi elvin,

welcome in the torkmaster program.

Please post results to the board,

I'm looking forward to it

Note that it has very low rpm.

Free wheeling i noticed tsr of about 0.6.

Most people on this board consider this as bad for

producing electricity.

They will say a low rpm,low power alternator has to be relative

expensive in magnets and copper,but I'm not 100% convinced.

I hope to have data on tork and tsr under different

loads soon.

cheers,

stonebrain
