I was trying to design the next big motor for my rocket, but stumbled on a couple of problems. Does anybody know why my graph is like this, it should be more like a plateau mountain.
Just looks like the grain geometry needs work. Looks like you're trying to make a sugar or BP motor. In any event on this forum we discuss research motors like this in the Research forum, which I'm sorry to say you can't get into not being US. Good luck.
