Maybe you can add more material along the way, thus creating a system that will compress more material together, which will create (hopefully) more pressure and push the rocket farther.

so you tried hot rockets that melt your nozzles, now in this video you have cryogenic propellant, so cold infact that you are not extracting all the energy out of it because of the cold exit temperature you know that if you combine both you will get something you could probably launch with decent payloads to hundred of meters?

Integza, look at the results you have obtained. 6mm expansion cup down to 3mm expansion cup made a massive difference. That aero spike nozzle appears to release more volume than the 6mm expansion cup. Reduce the size of the aero spike and it will work dramatically better

[@kadulous6357]

Have you studied the converging diverging nozzle? I know there’s ways to calculate the right nozzle size but for sea level the recommended shape is extremely simple. 35° convergence, some length for the throat, 15° Divergence. All you need is the length of the convergence and divergence and radius and you can get an easy and efficient nozzle. Also something else to add, if you want to get high temperature resistance I recommend graphite rods and a lathe to mill them into shape, they are fairly cheap for decent size nozzle and are used in actual rockets for their insane heat tolerance, also you could use some motor cooling like cold gas going around the nozzle before being combusted and exhausted out the nozzle creating a nice system. Anyway, good luck with your endeavors and I hope you read this!

[@nonchip]

wouldn't graphite burn on contact with an open flame though? heat resistance is pretty good on that, but it's just carbon after all, i think the flame would wear it down pretty quick and mess with the test results

[@Nuovoswiss]

I'll second this. Without water the CO2 comes out so cold that it loses a lot of potential performance. Adding some warm water (maybe 50°C) using a venturi injector should be a simple way to get a lot more bang for your buck.

Video idea: For more sustainable testing, make a nozzle testing rig using steam instead of CO2! Then you don't need to buy all those cartriges for static testing - only for freely moving stuff.

[@jonathanangladadavis]

That aerospike nozzle was amazingly beautiful to watch. Video idea: make an updated version of this but it uses multiple cartridges at once.

[@WouterVerbruggen]

Nope, no dry ice in there. The pressure in cartrigdes like that is about 55 bars, at that pressure CO2 is liquid (at room temperature). When releasing the pressure, you do get some dry ice out of it. That happens because of the enthalpy of the system, which is conserved. If the cartridge opening is small enough that is (Joule-Thomson-effect). You can see in the p-H diagram of CO2 that when coming from a liquid at 55 bar, dropping the pressure you end up with a solid-vapour mix at ambient pressure, due to the temperature drop. I use the exact same method to make dry ice pellets for the Leidenfrost experiments I do for my master thesis.

[@jacopo.gabrielli]

VIDEO IDEA: Since you have a lot of empty Co2 cartridges why don't you use as a tank for solid rocket fuel (for example the sugar one). With cartridges you can get a nozzle simply by going to countersink the hole. The divergent part will be missing, you could perhaps weld, on the outlet of the cartridge, a bolt or any suitable piece of metal and then countersink for make the divergent part of the nozzle.

What about if you make an actual rocket? Not just an engine, but a whole rocket that utililises something like a sugar based fuel, or if you want to go the cool route, use a nitrate fuel.

[@joshuaszeto]

cone nozzles found on rockets are that shape because they hold the high pressure of the propellant longer. The downside of having a large cone is that it starts to have significant aerodynamic drag at higher speeds and that they start to weigh too much. But in outerspace, the larger the cone, the more effective the rocket propellant mostly due to not having air molecules to push aside and weight isn't really much of a factor. Issue is still getting such a large cone up into space in the first place.

[@alexfrick3801]

Its not dry ice inside. It is CO2 liquid. Once exposed to the atmosphere, it evaporates and cools the remaining liquid into dry ice. Liquid CO2 is used in fire extinguishers and in large dewars for restaurant use. Dry ice can only exist below room temperatures, and liquid CO2 can only exist at high pressures. At regular pressures, dry ice sublimates into CO2 gas, and CO2 gas can be deposited as dry ice onto a substrate if the substrate is below 78 C. I am surprised that with his knowledge he didn't know this.

First off: It's absolutely amazing that you're enabling others to explore their interests and even run similar experiments by giving away printers. Ideas: RC submarine w/ depth control and thrust.

Maybe for demonstration you could make a long acrylic tank w/ silicon and additional support to seal the tank. It would be pretty sweet to see a multi-stage rocket. I wonder if you could achieve [reusable?] cold gas pneumatic separation with these CO2 cartridges? Overall seems pretty impractical since there isn't a lot to be gained in terms of stages (I would expect identical thin nozzles to remain the most efficient throughout phases since we aren't seeing changes in atmospheric pressure, and weight reduction is only a problem since we're making it one), but you know, s c i e n c e.

My suggestion for a video: Try to make a plasma engine, or something similar.

[@arifqurbanov2159]

Make an airplane powered by a rocket motor or an actual rocket.

For a future video, you should try making sugar rocket motors and seeing how high you could launch a rocket. TKOR has several great videos on the subject. Cheers! :)

You should try cool the nozzle of a fuel burning rocket a CO2 cartridge

[@PezDJ]

Build a lander for that multi stage rocket so you can send something up that can land using, parachutes, gyros and CO2 rockets for impact braking 😊. Kinda like a moon lander of some sorts.

Speaking of making rockets out of dangerous stuff, what about a thermite fueled rocket?

[@fanintezga4221]

i dont know if i win but anyway... Video idea: try to make an ion engine that actually produce some little of thrust(i dont know exactly it cost amount of wattage, but it will be fun). Also keep in mind that tomatoes are disgusting.

[@nguyenvinh7631]

Well you can actually put the uranium nuclear generator for fuel(electricity).

Idea for the next video: Ok, this isn’t relating to the CO2 part of this video, but taking the nozzle idea to a slightly different application. You know how in summer when it’s super hot and a pedestal fan you have is just not doing the trick? Well what if you can use one of the explores nozzle geometries from this video, but scaled up to fit onto a small pedestal fan. Then you can use the same fan to cool you down, but experiment to find the ideal ‘nozzle’ fitted to it to see if they make a difference to how efficiently/ well you can be cooled down. Seems like a fun build, but also a chance to see some larger scale 3D prints… 👍 Keep up the crazy cool vids though. Forza Integza!

idea: put this "rocket" on a 3d printed airplane
