I'm looking for a method to calculatute craft drag in Vizzy, so I need to calculate Drag coefficient and Reference Area.
How can I do that in Vizzy?
I found a crutch method to find width/hight of a craft by adding labels, calc length of vector between them.
Also, is that can be used in Funk-expression?
There’s really no good way to do this. You can try to experimentally find the drag coefficient of your craft. Another way is subtracting the expected acceleration (from the forces you know: thrust, gravity) from the actual acceleration. The difference is caused by drag, can find the force with F=ma. Although that way sometimes isn’t very good.
