Wind turbine: hub and blades replacement by larger?

[fam]

Hello

I am impatient to know the results.

For a detailed weather forecast:

The wind given by the weather is in principle at 50m high,
so you have to count down ... all that to see what happens to your wind turbine.

I use accuweather which is native on android
Today gives me 19km / h gusts 21 due north.

Must not understand English at meteo france.

For the follow-up no problems with the best possible results.
Function of the site and the neighbor. Because of it I will have to add a soft plastic calle (rubber stopper). Sometimes the basalt stone house collapses. The walls are barely 60cm, it's fragile ...

On the roof
I messed up something the GTI starts around 15 / 20v there is a delay and as it is small gusts it is not top.
However by measuring between each of the 3 phases I have the same voltage before the bridge
airx blades + cleats: it doesn't spin fast enough but all the time
5v 8v bridge output

airx blades without shims: I broke a screw, more balanced it shakes the mat seriously, it's a mix of allen btr and allen alu. the aluminum breaks when tightened.

I put an extension to the drift because in case of windfall it makes vacuum (the blades of airX) and it turns over on the wrong side.

Original blades: hard to turn.

I go down to get stuff: something without sugars
BTR and zero-stop screw ...

the aluminum breaks when tightened.

yes, a filth, which seizes and breaks, even the dural !!
Avoid as much as possible and tighten with dynamometer and anti-seize !!!

The GTI may have had a slight input surge ?????????????????
in strong winds ??????????????????????????

With the original widened blades, at 10.8v regular bridge output the red diode went out then the green one flashed: start of production.
It vibrated too much the neighbor's cafietirre.

For the consumption of my counter it displayed + 1w in 1 hour.
But it's my panels that allow it, despite 50% cloud

Small wind, the impression of speed is accentuated by the noise of the blades.
always a little lack of balance.
And drifts too small.
It smells of aperitif with the neighbor ...

Even stainless steel screws break what a brute.
Nothing in the grid
I have to unpack all the wiring to put the quick connections without sugar.
And I have no bearing or axis of the right diameter to balance on the bench. The weight of the airX blades causes the hub + blades to nose down. At a smaller diameter it does not rotate.

Rudely practical.
I put the turbine on the bench and launched the blades with a weight of 100g: aluminum gourd without cap


The airX blades have a lot more inertia.

Return of origin plus a large drift. And wait for the wind.

So?

with this 8/9 ms wind and gusts what does it give?

You would have to measure the wind speed where your wind turbine is to see what your location gives.
In the absence of an anemometer, empirical means, the piece of cardboard with a piece:

So. Never being at my house. I'm going to ask the neighbor.
Major work is planned soon inside.
There is not even a TV = that the beaver dam we see from the window.
I don't currently live there. I go there to tinker, feed the cat and pick up the mail.

Clever kick of the coin.
Edf's sagem cumulative counter reminded me of having 3kwh in the morning while it posted 8kwh the day before. ??? Thunderstorm at night? Reset???

Next change
I remove the angle to the airX blades with the calluses upside down. If we can.
To maximize speed and lower the whistle created by the angle of attack.
With airX blades no problems with starting.
