Submitted for your consideration (evisceration?), my first attempt at designing a rocket in OpenRocket.
The design is for a sport-scale Taepodong built with BT-20 and BT-55 body tubes. I say "sport-scale" because the "upper stages" are a little fat relative to the first stage, and the fins are slightly oversized.
The upper BT-20 would be one single part, even though it shows as two in OpenRocket--couldn't quite figure out how to get it to come out the way I wanted. Basically, everything above the transition section is one giant nose cone. I thought about simulating the interstage truss by cutting holes in the BT-20 just above the transition, and having a dummy second stage engine visible inside. (No idea how to simulate that in Open Rocket.) Do you think that would make the body tube too fragile? If so, any thoughts on how to beef it up?
I can guarantee, however, that it will fly better than the prototype.
