Backwash Causes Lift?

You appear to have the essential concept right. But aerodynamicists
call it "turning" the flow, which is different from what they call
"downwash." Here's NASA's explanations:

And if you click on "turning" you can see this explanation of the
term (and hopefully why "turning" was chosen):

And this is what aerodynamicists call "downwash" :

I wanted to thank you again for these NASA links. IThe more I read,
the more it becomes clear that is *not* universal concensus on the
basic mechanisms of flight, not even among experts.

I'm sorry but IMHO you continue to come to the same untenable conclusion.
There is consensus among the experts. I keep giving the NASA links not
because they are in any way unique, but because it is cheaper than giving
you a list of more books on the subject that you'll never purchase and
read. They seem ideal for this particular discussion and your specific
need.

There are simplified, and therefore inaccurate, statements about
electromagnetics in books aimed at general audiences. Yet would you say
that because of these statements there is no universal consensus about
electromagnetics?
