Magnus effect - and Coanda effect
I've been given some research to do - and I've tried, and tried...
With thanks to A.C. Kermode (Mechanics of Flight), I'm now aware of "Coanda" effect - water (or air) flowing over a cylindrical surface will follow the contour of the cylinder to the lowest point and then "fall off". Haven't a clue what we use that for in aviation, but I've read the stuff (briefly - need to go and study it properly).
What do we use it for?? I imagine that it will have something to do with airflow following the contour of the upper surface of the wing - but this goes against everything I was taught at basic PPL level about "separation point". I've obviously misunderstood something along the line...any help??
Now back to the original question...I cannot find any reference in any book (haven't tried an internet search...I'll do that next) about MAGNUS EFFECT.
What the h**l is it?? and what does it do??
