turbine blades are airfoils. Airfoils have an optimum angle of attack, where they will produce the most lift. In this case, the lift is rotation. When stalled, maximum torque comes when the blade is just off knife edge to the wind. As it begins to spin, the spin creates a vector, which requires the blade to be pitched more flat, to maintain optimum torque, as the rotor comes up to speed. Keep in mind, the rotational velocity is less in at the hub, and much faster, out towards the tips of the blades. The blades are actually twisted, so at a certain pitch, the whole leading edge of the blade from root to tip, is at the optimum angle of attack. At that point, the rotor is producing maximum power and minimum noise for the wind speed. The rotor is engineered to laminar pitch, at a specific wind speed, at a specific RPM. They use data they collected at the site, to determine what that average wind speed is, to determine transmission gearing, and blade tip to wind speed ratio. (usually between 5:1-7:1)
I’d love to see a giant smoke generator aimed at one of these so we can see what the blades do to the air! Also, what’s the db level from where you are at max speed? Those whooshes sounded amazing!!!
You would be amazed. If you saw the smoke, it would create a 'vortex' behind the turbine, turning The OPPOSITE direction of the rotation of the blades!
@@brianrigsby7900 The blades can rotate axial to minimize or maximize the winds angle of attack or the turbine itself can rotate radial 90° out. If all that fails, there is a brake disk like in a car only much bigger. On normal mode you just generate as much electricity as you need to not increase your rpm. So basically pull out as much as the wind gives until your turbine cant handle anymore, then rotate blades, then rotate cabin and/or brake (disc)

I find wind turbines very interesting

I just randomly get recommended a video of this particular nondescript white whirlygig.
the particular nondescript white whirlygig is basically an oversized fan that gives us power with the whooshy wind (somehow)
And it is what the algorithm needs, to be able to run
Meanwhile, your average twitter user convinced that we are wasting electricity to run these giant fans to blow wind around 😂
How strong wind was?
Is that a GE 3.2-130?
Yes
With this wingspan you must be at as much peak efficiency without gouging the ground beneath you as you can be
Did you use a diesel generator to get it started spinning?
No, the wind starts it. It's all about the angle of the blades. It starts spinning faster as they rotate more. You can see them rotate in the video.
im surprised this myth persists so much
It's not a myth.. it's the world's dumbest nonsensical fairy tale to not believe in wind energy...
How can they be stopped with such a wingspan…? And how can it control the spin up?
