How Open Roicket Calculate Drag?

[K Faris]

Hi everyone, how does OpenRocket defines the drag coefficient in its component analysis? i really need to know how because i want to compare a set of drag data that i got from using OpenFoam software.

If so we’re to guess, I’d say the drag equation, although I’m not really in a position to know.

You can always look at the source code: https://github.com/openrocket/openrocket

I've found the core calculations to be quite readable.
