It is actually the viscosity that produces lift, see John Anderson’s “Fundamentals of Aerodynamics”. To get the Coanda effect, the jet stream must come from some sources, such as the engine exhaust (upper wing blowing) or the bleed air from the engine (jet flap).

I cannot make sense of what you are trying to say, but it is wrong. tohclin View <abbr class='timeago' title='2012-07-14 01:09:01Z'>Friday, July 13th, 2012 07:09 pm GMT -6</abbr> http://www.terrycolon.com/1features/ber.html Carlosreplied: View <abbr class='timeago' title='2012-07-14 05:38:30Z'>Friday, July 13th, 2012 11:38 pm GMT -6</abbr> That web page agrees with what I say. But it is written in such a confusing style, I can understand why you think it is saying something else. There are much better references available, like the Wikipedia article that it links to.
