I almost never leave comments but i just have to say that i did not expect this quality of entertainment coming here, you really are underrated. Keep it up
You are literally the most underrated youtuber that there is! Your level of content quality comes in line with „i did a thing” and „backyard scientist”
You just became one of my favorite channels! I did pretty much the same thing a few months ago and I thought I would give you a propellant tip. The O/F ratio I use is 1.625. I came to this ratio after a good few years of testing. I saw a lot of gunk coming out of the nozzle, so I thought I should let you know. You can check out my last video to see the how that engine flew. Keep up the work anyway! This is some Integza type sh!t (but better cuz you actually do the math)!
Thats pretty cool! As an idea maybe you could melt the propellant a bit more with a little less viscosity(maybe add in tiny bit of water and wait for it to dry in order to make it stick more)? You could also experiment with grain shapes and such to stabilise the burn time and power. Good luck!
Really cool video! Looking forward to seeing more of this project. I have wanted to do something similiar myself at my university but havent gotten around to it yet, this might just push me to do it
I knew about nozzles and their purpose, but idk why, it's on this video that i got amazed buy the physics of it It is really a wonderfull piece of mechanics, no moving parts, relatively simple geometry (i guess) and such a great impact on the system performance I was amazed kinda like I learnt how work a High voltage Transformer by induction Thx, +1 subs !
Your sugar is caramelized and your potassium is chunked, which will reduce its effectiveness. If you dissolve the potassium in its own weight in water first, then heat the mixture until boiling and add the sugar to the water, everything will dissolve way better and cleaner, and the water boiloff will cool the mixture reducing the chance of fuel ignition. Once the mixture turns like honey or a little lighter in color and consistency, that means all the water boiled off (and the sugar can finally raise its temp past 160 degrees) and you should have a completely homogenous liquid without chunks. Be careful, because that mixture might be several folds more potent than what you showed in your video. If it doesn't cool to a hard candy, you don't boil off enough water.
You said you didn't have small enough lathe tools to carve out the diverging section, if you have drill bits of decreasing size would you be able to drill to increasing depths with decreasing diameters to get the rough stepping and then file/rasp away the steps to smooth it out?
You're right on the money here. I thought about doing that exact thing, but what I ended up using was the biggest reamer I had. It drilled out a sloped hole that is close enough to do some rough tests.

TH-cam's algorythm sometimes holds some surprises! Can't wait to see this rocket
nice first episode; hope to see more

its incredible i have also faced many problems making a solid rocket motor and i succeded and now i am building a pressure fed liquid rocket engine :)

you should put an aztec death whistle on the end of it. use ear protection
nice

Use Sorbitol instead of regular sugar, it is much simpler and you get better results.
38 subs for such a awesome video whaattt??? new I did a thing

How about you start from a simple basic engineering principle: read/learn first and only then do it yourself.
Hello, do you have a discord account? If you do, message me, i have some ideas considering solid rocket fuel synthesies. - a chemistry major.
