Hi everyone.
Can anybody share with me this SAE norm?
Actually I have used the Excel sheet to calculate my values also, but I am not satisfied with the sheet as I find the math in here too basic.
I have done a prototype version of a version (on Scilab) with least square adjustment that would be able to give a more robust answer, with least square adjustment.
At the time, I get 0.590m2 as a CdA for my car, with an estimated accuracy of +/-0.037m2 (1sigma). I did only 4 runs, 2 in each direction.
I am planning to integrate in the model some different values, including slope (this would allow to do the testing on a non-flat road) and wind speed relative to the car direction.
I am happy to share with you the results, and would be happy to get some raw data from you to test on the algorythm.
Best Regards
