Far as I can tell Martin did an awesome job on the
structure of the LIVP.
Notably, Martin said to me "No one should ever
stall a LIVP"
I'm afraid I can't credit the statement "The wing
tip is not designed to stall and as such the question of how it stalls is not
relevant" The lift vs. AOA curve on that airfoil I can only describe as
discontinuous. It goes from 100% CL to 50% in a small fraction of a
degree. (like less than .2). Washout doesn't make that go
away. If the root has stalled and the tips are all that is flying and they
are just a little bit different in incidence, guess what happens
next? Washout only gives you a little more time to notice what
is going on and get flying again before that happens.
There is no question in my mind that you don't want
to go there. I think most of the community agrees.
There is a huge question in my mind why experienced
Lancair pilots get there. I don't suppose I am better than any
of them. but I wonder what happens in your mind that you let it
happen, and how you can prepare for whatever THAT is.
