Does anyone have any figures and references for about what ratio lift

produced by Newton's Laws and Bernoulli's Laws?

All lift is produced by Newton's third law of motion. Air is forced
downwards
by the wings, and this produces an equal and opposite force that attempts
to
raise the wings, and that is lift. How the air is forced downwards is
irrelevant, as long as it happens. In practice, principles discovered by
Bernoulli and others play a role in diverting the air flow when this is
accomplished by an airfoil.

As said in other reply - not looking for a run-down on the physics -
looking for the *ratio* of lift obtained by each.

Simple answer, there is no "ratio" -
Newton 100% + Bernoulli 100%, total = 100%

It really is a "chicken or egg" question.

Google "Newton vs. Bernoulli"
and "Newton vs. Bernoulli" NASA

I recommend
http://www.grc.nasa.gov/WWW/K-12/airplane/bernnew.html

and much more

When done you can also work (troll?) on other important old disputes
regarding -
high wing vs. low wing,
track up vs. north up,
and slip vs. crab with a kick.

Happy landings,
