Drag Coefficient changes

[Excalibur_TA]

Hi I'm designing an airbrake system for a sub sonicc rocket and to enhance the accuracy, i wanted to model the change in drag coefficient after DeplloymentDo you happen to the know the equation or method openrocket uses to model the change in cd with velocity and other forces

 

[tfish]

method - launch it with the air brakes deployed and back out the CD from that flight?

I'd follow Tony's method.
