Wind turbine design

Former Member
Former Member over 10 years ago

OK not sure whether this should be here or in power management, but I am choosing engineering

 

This is a new subject to me in relation to the physical build of a turbine

 

I wonder if anyone can tell me why the vanes are perpendicular to the wind direction instead of parallel to the flow of wind

 

In my eyes it may be easier to build a turbine with variable direction blades depending on the speed of the wind so that they are facing the sky, which would reduce the directional workings from the complexity of the design

    I agree, over reving is a big issue also, more surface area provides better performance in lower wind situations. Larger wind turbines tend to create RF noise due the varying capacitance between the blades…

    Are now we are getting into different area of problems that I had forgotten about EMF and RF interference, I remember testing equipment against that (in an old employment) but had not even thought about…

    There are turbines with vertical blades, serpentine blades and so forth.  These are usually smaller because of the  complexity of the carrier assembly as the size increases.  

     

    However, thinking outside the box is the catalyst of innovation.

    From the start of the discussion has certainly given me some food for thought, with some ideas coming through
