Back to the original intent of my original post; It is quite evident from just these few posts that the hobby is full of a lot of theories and preconceptions that have nothing to do with the actual engineering or science involve. I guess I’m just beating my head against the wall hoping for some improvement in the accuracy of the sport.
Whatever happens makes airplanes fly and propellers pull.
That very phenomena is interpreted in as many ways as observers try to, as this thread and many more show.
Our brain needs the concepts and axis and divisions to make sense of these things.
There is only one force and one acceleration; however, we divide then in so many components, that the phenomena ends up being confusing.
By forcing a propeller through a mass of air, a unique reaction happens, which is beneficial to our purpose of moving the airplane forward.
We could say that torque is the reaction caused by the drag of the blades and that the thrust is the reaction caused by the lift of the blade.
Since lift without drag cannot happen, thrust without torque cannot exist either.
More AOA means more lift and drag; hence, a prop moving in a path that is non-perpendicular to its rotation plane will produce an asymmetric reaction, which we like calling P-factor.
Once leaving the rotating blade, what force would cause the stream of air rotate for long, if any rotation requires a centripetal acceleration?
