Sendary effect of rudder
Hi all, I am little confused about this phrase.
I do know what happens but do not know why...in details...
The secondary effect of yaw is roll due to the outer wing travels faster than the inner wing.
But how does it travel faster?? Is it because of the outer wing is more exposed to the Relative Airflow than the inner wing? If so, what is exposing got do with increase in velocity?
Anyone who can explain this??please? The simplest way?
