Re: Another maffs thing I don't unnerstand
Blade design is of course vital, but if you have 2 blades with the same design, but one is twice the length of the other, then under the same wind speed, at the same elevation, the longer one will generate 4 times the power.

Re: Another maffs thing I don't unnerstand
But the two blades would not be designed the same. That is totally hypothetical .

Re: Another maffs thing I don't unnerstand
The OP was hypothetical. I was struck by the mathematical relationship between blade length, area swept by the blades and the squaring of the energy output when the length is doubled. It was about the maths involved not the practicalities of wind power.

Re: Another maffs thing I don't unnerstand
Although friction, turbulence and whatnot make the increase in electricity output rather less than the increase of the swept area squared, it is not going to be linear.
Here's a real world comparison:
If the increase were linear, a swept area with a radius of 100 metres would produce 1.5 MW, given that a wind turbine with a swept area with a radius of 10 metres produces 0.15 MW. The actual output is more than twice as much.

Re: Another maffs thing I don't unnerstand
In the diagram above, let's compare the 1.5 MW turbine with a swept area of approximately 3420 square metres, with the 2.5 MW turbine with a swept area of approximately 5674 square metres. The power produced is almost exactly proportional to the swept area, as I have consistently asserted...

Yeah, some are confusing the design and engineering practicalities of turbine manufacture with the mathematical relationship between blade length and potential energy.Rum wrote:No. The story is blade length. That is what the OP says.Scot Dutchy wrote: ↑Sat Jun 16, 2018 8:12 amBlade length is not the story but design is.

Nothing.
Time to wind this discussion up, methinks.
