Hey cobalt, Look up "Introduction to Aircraft Flight Dynamics or was it flight mechanics..." Google book has it but has some pages taken off for more info on how to program a simple modified wessinger lifting line method. Also, if you can get access, look into AIAA or SAE papers and...

Thanks for your reply Phrak. When I run cases for taper wings and/or with sweep, it had negative values. But when I ran the model for straight, no sweep, no taper, it was giving somewhat correct results. I think I have fixed the problem. I had my control points at the 1/4 chord , in the...

Hi all, I have implemented a nonlinear lifting line method to estimate lift/induced drag of a typical wing. This method utilizes 2D lift coefficient data, and uses a numerical technique to solve the nonlinear equations. The program I have written in MATLAB is working, though I would like to...
