Considering the complexities of helicopter rotor aerodynamics I would suggest everyone be polite when discussing the many aspects of the matter.
We see these threads started fairly often and we see posts with varying degrees of sophistication and technical knowledge.
I would prefer reading discussions complete with astute knowledgeable responses that serve to fairly advance the discussion and some times downright debate.
I have no doubt there are some among us that do know what they are talking about, there are some who think they know what they are talking about.....and there are some like me who know when to sit quietly and occasionally nod their head as if we understood what was being talked about.
My knowledge comes from Prouty, the Sikorsky Blue Book, and various other sources....and as an Instructor I taught the subject but even then I knew my own limitations.
I also passed on to my Students the advice I was given very early in my learning....."There is no such thing as a stupid question other than the question not asked.".
The rest of the advice was to carefully consider the answers as some of them might be absolute rubbish.
One has to consider the sources and compare what they have to say and how it was said and sort out the wheat from the chaff.
