WebSep 24, 2015 · The downwash from wings and rotors go down. They do not increase thrust, they are the thrust, according to Newtons 2nd, which causes the propellor to pull, and the rotor blade or wing to lift. – Simon. Sep 24, 2015 at 5:54. It is only called downwash on a wing or a rotor. On a propellor, it is called prop wash (or other terms) but the only ... WebOct 21, 2024 · If no downward acceleration occurs, there can be no lift. However, a wing of infinite span will use an infinite amount of air for lift production, so an infinitely small amount of downward acceleration already suffices to produce lift. Clearly, this is a thought experiment that cannot realistically be reproduced in reality.
