Hey! First post on the forum! I have build a ton of small "firework-sized" rockets, but now I'm looking for a bigger project! I was planning on building just a rocket engine to begin with, and will try to optimize that before starting on the rest.
So here's the project: Build a rocket engine, roughly 100mm in diameter and maybe 600mm or so in length, though the dimensions are not important. Whatever's optimal really. it'll be just a regular kno3 + sugar rocket as getting materials for other fuel sources is pretty tricky where I live, at least for right now. I am planning on simply making concrete nozzles, so I was wondering if that would work well at this size (though I realize they will be single-use, and far from optimal)
I was basically just looking for some pointers, if someone knows about any similarly-ish sized engines they could share some plans for that would be greatly appreciated! As well as what kind of performance I could expect given the very "diy" approach to this.
