Hey Crab I guess I am not making myself clear, appologies:
I think where you are mis-understanding me is in the distinction between the pre-stalled cruise peak AoA (at about 9 o'clock) and what
then happens after stall develops when the response to that (flapping down) will create an
increased AoA further around the cycle.
So there's:
peek AoA
before stall and
peak AoA
after stall
not a contradiction i think you must agree (?) if you do agree you could possibly re-read the post to avoid repetition
- does that make it clear?
Aerodynamic effects do not produce symmetry of pitch, only symmetry of lift.
- that's true (ish) - but the cycle dis-symmetry is what I was talking about - that's why flapping to equality is not really the mechanism which counters dis-symmetry of lift (generally) -
but that really is a different story ... perhaps for another thread?
