Hi all,


So, I had all these XLS open... had created one for quick NACA/Riblett ordinate creations... but I just messed up... saved another file on top of it and boom! it's all gone.

Quick question, when I do type the Stations, different distributions, and mean lines... how do I get ordinates for tope and bottom?
I know I re read the book over and over again, and there was a post here somewhere on how to do this, but I can't seem ti find it... It was form Adam or Tim...


All I need it, a simple guidance of (as an example )

Upper_Ordinates = Meanline + Thinkness% * Distribution
Lower_Ordinates = Meanline - Thickness% * Distribution

I'm going from memory here... but I'm missing something as the values don't plot correctly... what did I miss.

Can anyone help me pls.
