  • Why the strange upper surface?Does it increase lift?

  • That is to mainly decrease the drag. We create the strange surface so that the flow will have early "tripping" from laminar flow to turbulent flow.

  • hmmm, blades oriented like that may give maximum force at 0rpm... but it's supossed to spin : S

  • Looks like a fish!!! Any design that copies nature will be more sucessful i think

  • so would you get more power in unsteady turbulent airstreams
