New airfoil series for small WTs

First of all: A good new year. To speed up discussion of small wind turbines: I have designed a new series of airfoil's for machines off about 2.5 m in

naca 0020 zero camber  and maximum thick of 20 %. we can fabricate this turbine blade using japper machine.. if we want more efficient blade we should go for

Re: Just getting started

I was hospitalised so couldn't reply you properly. I will send the list with respect to  rotor radius. Do you know midic slobodan in xfoil group? I selected

Re: Just getting started

Hallo! What is a "reasonable airfoil"? NACA 0020? Hugh Piggotts are very specific - for shure you can explain what it is. :-) That's the "reason" why they

Re: Just getting started

Hallo! wombat! Yes- This tube airfoil is similar to Goe 417a- well known for low Re purpose of gliders - see e.g. Schmitz. Good Perfo. With this airfoil you

Re: Just getting started

Hermann, you came thru OK here. Just do a "google" for wind turbine airfoils, should find lots of info. FWIW, the blades made from PVC pipe do pretty well - if

Re: Just getting started

At some point you should just build one. You will probably find many things you will want to do differently on the next one. You seem to me mired in

Re: Just getting started

Hallo Karti! May I ask which are your existing airfoils and new airfoils? (The airfoil series). Many small and big wind turbines suffer from a wrong choice.

Re: Just getting started

Optimum means for particular range wind speed it will work better. I'm building and doing on simulation also. on one can do in paper. 😆 karthikeyan Sent

Yes of course . first of all I will complete fabrication of the generator and other things based on my calculations.  I'm parallel looking for multi objective
