I've done a fair bit of searching and talking about sizing drogue chutes for deployment at apogee and still haven't found a good estimator or 'rule of thumb.' I know for example that Rocketman has a drogue sizing chart. However, I've been told my drogues are either too large or others say too small on a particular flight. I've also been told that you want an 'inverted v' coming down and many of mine had this. While most of my >20 dual deployments have been successful, most of them have been deployed under 4000 ft for rockets varying from 6 to 50 lbs. I'm sure really high altitudes call for different characteristics. So, what do you all recommend for sizing drogues? Any simulation programs out there? Rules of thumb? Etc?
