This looked like an interesting extension of my skills, so I picked one up.
First thing to note: No instructions, no available OpenRocket models, and an incorrect parts list. Took me an hour of moving parts around on the floor to figure out how everything goes together.
Attached is an initial OpenRocket model. I'm having a couple of problems with this, and hoped someone might have an idea.
1. "Warning: Discontinuity in rocket body diameter". Man, does this error annoy the heck out of me. One of these days, it's going to annoy me enough to go git the source, find out where this message is displayed, and modify it to IDENTIFY THE COMPONENTS that have a discontinuity. I've looked at each section, and everything looks like it should be continuous - anyone have a suggestion?
2. The transition section and the lower body tube should butt up against each other, with the internal coupler providing support. OR doesn't seem to handle this well - it insists on sliding the lower body tube inside the transition. I had to create a "fake body tube" that pushes the lower body tube down to where it belongs. My sense of aesthetics hates this. Anybody have a better solution?
3. No matter what I do, OR refuses to save any engines I configure the rocket with. I configure and sim the rocket, everything's great, then I save, exit, and restart - and the configurations and engines are gone. Any help here?
I expect it'll take a couple of months for me to get enough time to finish this; I'll update the thread with pictures as the build progresses.
Thanks,
