Wing Stall

I had a set of video magazines from sometime in the 80's that had a clip of
someone famous doing exactly that, except he used pieces of yarn and had several
dozen on the wing. I don't think I have the videos any more. It was a video
magazine for pilots that only lasted 2 or 3 issues. Wish I could remember the
name of the mag. The speaker on that segment might have been Barry Schiff. The
same series had Chuck Yeager's time to climb attempt in a conquest, and had a
segment on that gulfstream outfitted with cameras for filming aircraft in
flight.

Chuck,
You didn't happen to video it, did you? I've been looking for exactly that
kind of footage for my ground school class to show exactly what you've
talked about.

I did an interesting experiment in my Archer yesterday. I've read about
the
wing washout and know the soft stall of my Archer but yeaterday I saw it.
Using small pieces of duct tape, I put eight, six inch ribbons on the left
wing
- four along the leading edge, back about 10 inches, and four, 10 inches
forward of the trailing edge.

At 3,000 AGL, I slowly decreased speed while holding altitude. For the
longest
time they all streamed. Then the most inboard aft "came loose". Just
before
the break for the stall, all four close in ribbons were stalling and the
four
out ribbons were still streaming. The Archer stall is mild and is a
series of
scollops. The outside ribbons, in the area of the ailerons kept
streaming.

I saw what makes this a forgiving plane and a good choice for the
occasional
pilot.

Chuck

Kerschner for sure spent some time tufting his plane. He also added little trailing
cones and some interior pendulums to work out the dynamics during spins. He
has a rather humerous talk on his escapades with this (both the results of the tests
and comments between him and ATC when he flew the tufted plane into a controlled
field).
