Desertfox - Thanks so very much for your help with this. I'm not familiar with Rankine-Gordon but I'll look into that.
rb1957 - N=3. (Ground support Equipment. What do you think? Still use Johnson?
1. I have a slenderness ration of 23.7 and my material is steel. The appropriate range for steel is 30<Le/k<120 (Structural Steel) what do you do with the equation if the Slenderness Ration is less than 30? Do you use Euler's Formula or Johnson's formula? I can't remember.

Felix,
I allow for the variable wind speed from surface of the water to the top of the mast through tapering the foil (Leading edge constant). It's relatively easy to do because when the foil is adjusted it adjusts in unison throughout the whole (Bottom to top) foil. So, The boundry layer near...
Quite a bit. I have a mechanical working model of the conformal wing. It's a single point actuated wing that changes 3 sections of the wing at one point. I not sure if you can post pictures on this but if you can I leave a picture I have of it. I'm going to try a model of it on a friends RC...
From personal experience some of the origin winglet work was done by Dr. Konig at Mississippi State University (I worked in the wind tunnel during my sophomore year). If need be he would take calls from anyone with this sort of question. He was always helpful as a professor. I'm not sure of...
I can't talk about the Eppler airfoil because I don't have my airfoil info in front of me but I would think a simple sail such as 0012 (12% of chord), 0010 (10% of chord) etc. would give you the ability to tack with the same sail effect on either side of your tack plus they (Percentage foils)...
Hey,
Does anyone know of a reasonably price lab to analyse a formula that could test for Conduction Coefficient, Specific heat, viscosity, density, surface tension, saturation pressure vs. temprature, etc.
Any help is greatly appreciated.
I start with a NACA 0012 wing cross section. I then can magically curve the chord line to form an smooth arch around the 30% so that the leading edge is much like a droop nose and the aft magic chord forms to a 15 Deg. slope at the 66% pt and about a 30% slope at the trailing edge.
Can anyone...
