openMotor VS RocketPy

keep away from PVC tubes, cause those shatter rather than peel like with cardboard or aluminium tubes. and unlike aluminium, it doesn't turn up in x-rays. don't follow online video tutorials, cause they're often simplified massively and don't explain the complexities. anyways, here's an online video tutorial (ironic) series by someone who's built much more complicated motors than pvc tubes packed with sugar. He does this at MIT, and also co-made OpenMotor, a software to get estimated chamber pressure, KN (a value proportional to the chamber pressure and surface area of burning, can't remember the exact formula for it), and thrust, plotted on a graph relative to time. There's also this site, which is basically the archive of someone who's been building amateur motors for decades, and it contains hundreds of separate pages, most of which contain extremely useful information, especially the theory section. I'm currently designing my own motor using sugar too, and these have all been a massive help.

You’ll also need a casing capable of safely handling the pressure, so you might as well just get a commercial reloadable motor at that point. It would be a good idea to take a step back and stop making your own motors until you have enough experience with reloadable motors to understand how they work. A good way to get familiar with the design aspects is to try replicating the performance data from existing motors in OpenMotor, which you can also use to design experimental motors around a commercial motor case.

No! It's RocketPy's Version 0.13.0 that is out now! Our biggest release so far accounts for many, many new features. 13, to be exact (actually, there are 22). The main ones stem from the Environment Analysis done both for EuroC Rocket Competition and Spaceport America Cup, which can now be accessed here: https://github.com/RocketPy-Team/RocketPy/blob/master/rocketpy/EnvironmentAnalysis.py
