How the GE ' Dump' setting works?

Hi

I trying to figure out the GE ’ Damp’ setting.

From somewhere in this forum I was reading once, the ‘Damp’ setting presents a simplified aerodynamic drag. What this is meaning, I try to test out now.

The basic drag formula is
Drag = O.5 * velocity**2 * cross area towards to velocity * atmosphere density * coefficient of drag

It looks like the ‘Damp’ value is some sort of blur combine of cross area towards to velocity * atmosphere density * coefficient of drag…

The questions are:

  • Is there any deeper documentation about ‘Damp’ settings?
  • Is it possible the adjust the object ‘Damp’ value with AP/python?

The attached file compare the GE ‘Damp’ drag to the calculated drag.
