Why do you have pitch on the blades?
WW is asking why are the blades at an angle to the hub that is not square ? The blades on the device in the picture have pitch:
https://en.wikipedia.org/wiki/Blade_pitch
I suppose a translation could be understood as 'why is there pitch (black sticky substance) on the blades?'
To be precise.... why is the blade angle of attack other than zero?
Oh, you meant an angle of attack. Blades are turned but not too much
