How much does Newtons 3rd Law account for Lift in %?

[06mangro]

I would like to know how much of a % does Newtons 3rd law (action / reaction) account for lift of a chopper.. i would also like to know this for Bernoulli's principle..
Can you give a source to back it up?

I can't find an answer any where

100%.

Bernoulli's principle.

Applies above and below the rotor, but not across the plane of the rotor, because energy is added to the air (work is done). Link to NASA article for propellors, a similar case:
