How does the wing that drops in an uncoordinated stall have a greater AoA?

Asked by: 2804 views Aerodynamics

Aerodynamically, how does the state of being uncoordinated affect one wing to have a greater AoA (deeper stall) than the other, thereby creating a situation for a spin? It might be hard to explain through text, so any reference resources are appreciated.

    The aft wing is staying slower, as such it’s AoA is greater. This isn’t the only factor, however. Google stall propagation on a swept wing. A side slip gives a similar flow pattern to the slower moving wing as the flow pattern seen on swept wing aircraft.

    The result is a wing whose tip stalls and the stall propagates both forward and inward. A highly undesirable characteristic of delta wings. And the reasoning for these aircraft needing stick shakers.
