Well thanks, but...

TFA is about the EX 181 driven by Stirling Moss. This is the EX 135:



Just—you know—for the record.

I find many of the shapes shown to be very satisfying to look at.

Maybe I need to be psychoanalyzed and have my head checked out. My older sister would claim it's all sexual or some nonsense. At least that was her claim when I was a child drawing airplanes all the time.

The EX-181 photo at the start of the article and the sectional drawing are just wonderful.

I'm not exactly sure why reverse airfoil shapes like the ones Luigi Colani has experimented with were not explored in the 1930's-1960's (paper is 1957).

I'd like to print out this article and paste together the bisected drawing. Does anybody know the command sequence for this?


...............................from the article: no #3


1. Air Resistance

2. Rolling Resistance

3. Ground Plane Interactions?

Why do we simply roll #3 into #1?

Isn't the ground pressure plane more deserving as to being it's own category?

Close but it's not elevated above the ground plane, and isn't as flattened out (especially at the tail).

Your older sister is completely right, of course.

Why don't we multiply Cd by 1000 and call it K-factor?

Grab screen shots and paste them together in Photoshop. Easier to raid Google Images:
