Just checkin'

Some guys like to think it's the airfoil.


Gotcha. It's a bit ironic. You go to all the trouble to build a neat looking
elliptical wing (I love a Spit and a Jug for that reason) and you get a
sharper stall than a plain jane rectangular wing. 'Taint fair!

Yeah, but you reduce induced drag and bending moment,
so I guess it's a wash...

I'll still go with what I wrote.

stick some vortex generators out in the last yard to the tips and see
how that goes at keeping the flow attached Mr Shankland.

dang I'll need to build my turbulent with the slots.

I wouldn't change a thing, actually. The abrupt stall isn't a problem at
all - if you know it's coming. After the stall, you can hold the stick in
your lap and, if you are quick on the rudder pedals, you can maintain a heck
of a rate of descent in a level attitude. Let it go a bit too far though and
she'll be in a spin right now. Normal recovery technique stops the spin
within a turn.

Just like putting some washout into a rectangular wing.

So, what's wrong with the sharper stall? You just learn to handle it.
According to Ball's Book on Bonanzas the Early Debs don't have any
washout (just a small stall strip) and they do have an abrupt stall
with a strong tendency to drop a wing in the landing configuration.
The stall is abrupt clean or in departure stalls, but predictable and
easily handled with no altitude loss.. They are a "rudder only"
airplane in the stall, but with practice you can learn to hold the
yoke back and keep it stalled while using the rudder to keep it
balanced. It does take practice and this is going far beyond stall
recovery.

When it drops a wing, you keep the ailerons neutral, ease off on the
back pressure and stand on the opposite rudder to stop the turn. You
do NOT shove the nose down unless you want every thing in back up
front with you or on the glare shield.

Departure stalls and accelerated stalls (clean) and approach (landing
configuration) can be handled nicely if done promptly with the
appropriate inputs at the break.

No, I'd not recommend them for student pilots, pilots who only do
things mechanically, and pilots who don't practice until the recovery
becomes instinctive. But these characteristics are pretty much a fact
of life for most high performance aircraft and particularly older
ones.

Rog .........

I have a couple of hunnert hours in Vee-tails and Debs. Believe me, they do
not stall sharply compared with the Emeraude. I think if you read my later
postings in this thread, I was *not* complaining about not being able to fly
the airplane (sorry about the double negative. I will say that it is much
harder to become proficient at detecting an incipient stall. There is
virtually no warning burble.

There are other effects of the abrupt or "clean" stall as well, especially
in departure configuration. You soon learn to stay well away from that
attitude, but you are so uncomfortably pitched up to achieve one, that it's
easy to avoid.
