Wing

[bunnyrabbit7_withnews]

The wing can be improved by using the recursive ratio of PHI in the
upper cross section of wing shape. The ratio must also be used for the
upper surface camber from bottom leading edge to end of top trailing
edge. Then add powdered pumice to the final paint for the upper
surface, before the final coat. This can be found at Home Depot. The
wing can be made of pumice which must have a stiff underlayment. This
is even better because mini-vortices are generated which combine over
the wing, and aggregate into the vortex. Further it seems that a bead
of caulk laid on the upper wing of about 1/4 inch height, and 1 inch
from the trailing edge, would entrain the vortex in a smoother manner.
This came to me by inspiration. It could be wrong, but then again, it
could be right. What say you?

Dear Bunny

Please tell me what this all relates to. I design
airfoils on a computer program (Xfoil, Profili)and
am hard pressed trying to understand your material
below.

I'm going to have to get some help! I'm wondering
if the recursive ratio of Phi is pointing to
something like the curvature of a logarithmic spiral.

Making a (airplane) wing out of pumice doesn't make
sense. I do mold graphite cloth to form wing structure
...which is cartbon and black and which provides a very
"stiff underlayment".

Using a rough texture on the surface can sometimes
be helpful in in achieving flow attachment on model
sized small wings at low speeds ...otherwise
it merely increases drag.

The bead of caulk does ring a bell except the
dimensions are outsized and the placement strange.
One is led to the conclusion that the wing is quite
a bit larger than what I work with.

A rectangular strip of about 2% of the wing chord and
placed on the UNDERSIDE of the extreme trailing edge
is called a Gurney flap. It increases the lift of the
wing. In some cases with the use of a thick symetrical
airfoils on the stabalizer of a helicopter a double
Gurney --top and bottom -- is used to eliminate control
"dead" spots that occur at zero angle of attack.

A rectangular strip just back of the leading edge is
called a turbulator. A strip back of the 50% position
is called an "invigorator" ... all having an effect
on airflow intrainment and attachment.

I am rather curious as to the circumstances of your
particular inspiration and just how it relates to
the spiritual material of the aerodynamics of RA.

Only angels have wings??

For Bill: I meant to post this to yahoo groups gravitic solutions. It was a
mistake, but serendipitous non the less. The wing is courtesy of Robert
Patterson. It is a double spiral with the fuselage in the middle. The fuselage
trails to nil at the rear of the wings. The wings are not a true recursive of
PHI. They are a flattened version. They are counter-intuitive. As air flows over
them it is entrained into the counter-clockwise spiral of the wings, which
terminate in a point after one spiral. They force air ahead and downward of
themselves creating a partial vacuum overhead. Lift. We can take this off topic.

Hi, Barney,

Thanks for clearing up the mystery. Of course
the bigger mystery by far is how strings were
pulled to arrange your particular posting error,
that by an amazing repetitious "coincidence"
serves my needs so well in setting my mind at
rest.

Thanks. I will stop berating myself for those
aforementioned perceived past mistakes that
have been hanging over my psyche like a dark
cloud these many years.

Interesting that you used the term
"serendipitous" below as that was the basis
of the name (Siren-Dipity)that I gave to the
last airplane that I designed specifically for
her use.

Thanks for being used!

Bill G
