Subject: | Re: KIS TR-1 Airfoil |
I got the late Harry Riblett GA AIRFOILS Book the other day.
He has some really good information and fixes in his book, and the story about
how he comes
to develop his own airfoils the GA- series.
In the book is a quick fix for the NACA 64-212 with a cuff going 10% of the chord
on
bottom surface.
Instead of the super elevation LE of the NACA, he draws in a 12 degree initial
camber angle
and a new mean line that create the cuff. The good with this mod is that it maintain
the
laminar flow. Not so with VGs
This cuff on the KIS-1 will be about 8 mm forward and little more thickness under
the nose, a
little to much for a micro job, but hot-wire foam inlay and class, or pre moulded
will work.
He also show that the flap top should have a raised and curved surface, this is
not really new it
have been used on many plane since before the WW2, but by making the control surface
thicker then the true airfoil, it re-energize the air, so it follow better and
also have less drag,
almost as there was no gap from beginning.
This will work on the elevator as well, but then at the bottom.

Jan, Would this mod change the flight envelope, move it, widen it or
what? Since it would increase lift, would it up the useful load? Thanks for
your reply.

I will test it in virtual wind tunnel, and we see if it as good as Mr. Riblett
say, what we can see is that the nose is corrected and this lead to increased
camber, as seen the original nose is above the chord line, meaning it have less
camber and initial mean line slope then the original mean line it self, due
to the way Naca place the original uncambered airfoil 63A015 along the mean camber
line.
more camber give more lift and higher max CL, but due to the change in camber is
at the first 10% the negative moment in unchanged.
the dropped nose will increase the stall angle.
It is late here, but I will pick the coordinates out tomorrow, and see what the
DesignFoil program say. but as with all computer program they are poor at detached
flow.
