Q&A: ARE THERE ANY REASONS WHY A LARGER NUMBER OF BLADES WOULD BE MORE EFFICIENT ONA WIND TURBINE RATHER THAN LESS?
May 13th
Question by Isabella:
Are there any reasons why a more massive number of blades would be more efficient ona wind turbine rather than less?
For science, we did an experiment to determine whether 3, 5 or 7 blades were more efficient on a wind turbine. Our results showed that seven blades produced a higher voltage, and three the least.However, now we ahve to find theoretical background which would support this, and everything I find on theinternet states three is superior than more. does anyone know any benefits of having more blades?
Thank you.
