What is a 'karmen'? I couldn't find it in any dictionary.

  

 Thanks,

  

 Richard

I will work on getting a drawing out on the web site so it can be

 duplicated..we use it for setting the wings to match.we set one, than set

the next one to match..

Take a clear plastic tube with water in it. Line one wing up with the wing

 root. Line the water level at one end up with the leading edge where the

wing meets the root. The tube goes under the wing and up to the trailing

edge. Measure the distance from the water level at the other end, to the

 trailing edge. This measurement is the vertical height difference between

the leading and trailing edges.



Hi Colin,



   I used a "water level" extensively when rigging my Pitts.  The neat

thing about it is that it can be any length - such as wing tip to wing tip.

 The method you describe above should work.  However, I think the new

incidence jig that Lightning has come up with will be simple and likely do a

more precise job when using one of the new digital levels.  But as I said,

 your "water level" method will work.



Blue Skies,

I used a simple system that worked well on N8WN. I put a 6" 2x6 directly

above the aft "C spar" of the wing then placed the digital level on the

2x6 with the forward point of the level on the wing on top of the main

 spar. I repeated this mid span and then on the tip of the wing. As I

suspected I had some (minor)  difference in twist between the two wings

but not enough to matter. I set the incidence on the left and the wing

 matched the karmen perfect. On the right I had to place downward force

on the leading edge to bring the wing into 0.2 degree of the left wing.

I then had to add micro balloon mix to the top forward of the karmen

 about 1/4" to bring it into alignment with the wing. The bottom on the

wing is not a perfect match but with years of experience with composites

this is about normal. Not a big deal at all. What matters is the

 aircraft flew hands off without any roll at all.   Johnny

Richard, 'Karman' is Spanish for 'wing root shape on the fuselage' or

that's what I figured it to be 



I tried everywhere to find a translation on European translation

websites but they can make anything of it. I would be good to find out

what it actually means.

 Richard,

     Karmen or more properly Karman (probably named  after professor Von Karman - well known aeronautical engineer) is a term used to  describe the raised (or molded) portion of the fuselage that mates to the  wing root and thus "fairs" the wing into the fuselage for less drag at the  junction of wing and fuselage.  As far as I know the term is only used for  composite aircraft where the fuselage mold includes a karman so that when the  wing is attached you already have a drag reducing junction.  

 Blue Skies,

 Buz Rich
