Anyone use the Rocksim / Openrocket base drag trick?
In the Apogee newsletter #154 Bruce Levison shows how to use a zero mass cone at the back of the rocket to simulate base drag.
Openrocket understates the stability of short stubby rockets and this trick is supposed to compensate for it. My problem is, he didn't clearly define just what qualifies as a short stubby rocket. He said the trick is for rockets with "much less than the normal 10 to 1" length to diameter ratio. He's pretty exact with how to draw the cone but not with what rockets you should apply it to.
