If the H.T. always need to provide upward lift, we shall increase the H.T. non-stall AoA by optimizing H.T. taper ratio. Right? Assuming we keep AR constant, so that we don’t pay stability for it.
But if the tail always needs to provide negative lift, shall we still do that? It seems that sometimes we actually hope the tail to stall a little earlier. Otherwise if the wing stalls before the tail, there will be a larger possibility to go to spin. Is the thought correct?
And what if the H.T. needs to provide positive lift sometimes and negative lift at the other status at the trim? Then how to design its non-stall AoA range?
I once read about the H.T. non-stall AoA range design method from a book, but forget it is which one. Anyone could give any reference on this issue?
