Hello all,
I sincerely hope I am not waisting valuable space here:)
I have been reading a lot of posts regarding some interesting dynamics regarding the flight of unpowered rotary wings. Like weather they fly backwards or not......just for instance:)
Anyway.....this is a great website, The first link is about gyroplane and helicopter aerodynamics. Check it out
http://www.garmin-air-race.freeola.com/links%20listing/41.htm
I was wondering if carefully placed air ejection ports were installed along the cord of the blades at the tip to reduce drag from tip voticies. Just a wild thought. Probably not practical. The mechanics would prbalby not be worth the result. I know there are Sailplanes that have used this process attempting to maintain a laminar airflow across the cord of the wing. ( the German Discus). Maybe some of you number crunching engineers could give me your 2 cents worth:)
Have a Great day:)
