Where to Find Moment Coefficients?

[physicsCU]

Is there a website that has these?

The NASG database doesn't list values, just a plot (not the best way to read values!). The .dat file with each polar curve seems to only be lift, drag, and AoA.

Any help is appreciated!

Assuming you are speaking of aerodynamic moment coefficients, you should understand that they are different for each different aerodynamic body shape (not to mention their change over different speed/Mach ranges). Do you have a particular shape in mind? There are some really rough means for estimating them for simple shapes, but the best estimates come from Computational Fluid Dynamic programs and the real data comes from wind tunnel tests.

There are a few websites where you can find moment coefficients for different airfoils. One popular website is airfoiltools.com, which has a large database of airfoil data including moment coefficients. Another option is to visit the website of a specific airfoil manufacturer, as they often provide detailed performance data for their products. Some universities and research institutions also have online databases with moment coefficients for various airfoils. It may take some searching, but you should be able to find the information you need.
