Do not use syringes, use pressurized tanks instead! Take two pressure tanks for propellants, and third tank just for compressed air (a few bar in Coke bottle should be ok). Connect both tanks to third one using some valves. When valves open, high pressure air will push the H2O2 and catalyst out of them into the chamber. This is safer since you can close the valve in case of emergency. This also would provide better control of the mixing ratio. Also a good idea would be to use check-valves to prevent incidents of pressure backflow from chamber.

[@MartII89NL]

Yes and maybe CO2 canisters instead of air pressure. Although with the speed of the reaction it might be difficult to control.

[@hufca]

​@@MartII89NL I didn't mean to control it in real time, but to adjust the flow rate of ingredients before the test (some sort of pipe narrowing or half opened valves). And since the ingredients used by Integza aren't flammable, I think CO2 would be redundant.

[@Scavage0001]

Think this will only work if he have the two chemical in 2 Ball shape Tanks, because of the pressure aerea. But also there need to be checkvalves so that the whole think could only react in the chamber, remember that there is a lot of pressure in the rocket

Two points about rediscovering old chemistry. I am a lot older than you and our chemistry teacher in 1966 was working during WWII in developing 100 vol hydrogen peroxide for use in rockets etc. He was called Dr Roper. As far as I know the V1 a heavy brute of a rocket needed to be shoved up into the sky at reasonable speed before it would fly off it’s pulse jet. This was achieved as aircraft on an aircraft carrier. That is a tube with a slot along the top on which the rocket sat on top of cylindrical slug. The slug was propelled up the launch tube by the mixture you are describing. The slug fell away in front of the launcher. There is one by the road visible through the hedge at Duxford Museum near Cambridge UK. The steam generator is also there with quite a number of chambers and pipes to hold and control the chemistry. The are bound to be pictures somewhere of it perhaps on Wikipedia.

A good idea might be to keep using the two syringes and have a small yet powerful electric motor( low KV, 150-350 KV probably ) and a setscrew to simultaneously push on both plungers. If the speed of the motor is to high, i recommend printing a gearbox to increase torque while slowing down the rate of fuel consumption. I understand that this complicates things a great deal, but hey...it's Nazi rocket science, what did you expect? Anyhoe, well done! Keep up the good work.

[@mariuscodori193]

You would need to control the reaction better... Slowing down and speeding up the movement of the serine won't help. The reaction speed is only one, to use some kind of gearbox, you whould need to convert the energy, like he mentioned, in an steam engine way...

[@vernonvouga5869]

To follow up on this, what about the proportions between the catalyst and chemical, do you need less peroxide, or more? How about a hydraulic system with a proportioning valve that uses two hydraulic rams pushing the syringes?

[@Liedson9000]

To add my own convoluted yet I believe highly functional method: Pressurize both liquids into separate canisters using a compressor machine at home, and then use electronic controlled valves to release the high-pressure liquid. This allows you to fine control the amount of each coming out, as well as increase their speed upon contact thus mixing them better. The valves would be controlled by something like a raspberry pico or an Arduino. I know this method is very convoluted and complex, however, it is the best I can come up with right now.

[@ghosttheoremproductions5469]

Catalytic reactions are typically directly proportional to the surface area of the catalyst. Swap those beads of silver for silver mesh and place in the nozzle. H2O2 which doesn't react with the KMnO4 (common, due to the violent nature of the reaction and limitations on reaction vessel volume) will get another reaction chance with the silver (it also promotes mixing). Also, a bit of tweaking to the design of your reaction chamber and mixer will help limit the backflow issue you're having. For the mixer, redesign to make it conical around the nozzle (the cone going IN to the chamber) and for the reaction chamber you can add angled (baffled) steps to the side so that expanding gasses favor moving towards the walls of the chamber and nozzle (this also reinforces the chamber which allows you to make it thinner/lighter). Beyond that, you just need to get the H2O2/KMnO2 ratio correct and figure pump(s). Bonus points if you put Tesla valves between the pump(s) and mixer to further limit pressure backflow. - Video idea: Steam Rocket Engine 2.0

[@skybirdprojects5489]

Redsigning the injector for higher pressures so that the catalyst and catalyzer can be atomized before mixing would help.

[@Bigwings2043]

I think the reason his test at the beginning didn’t work so well was because of the lack of surface area.

[@satriahanifrofi9798]

[@pabloarroyo1023]

The silver is also likely oxidized, limiting the amount of actual catalizing that occurs. Putting the potassium permanganate in a blender to make the particles more fine may also be smart so surface area is increased.

[@ghosttheoremproductions5469]

@@pabloarroyo1023 - Silver doesn't oxidize by itself as it has an incredibly low affinity for oxygen. The most common oxides are all dark so the silver wouldn't be shiny if it were anyways. As for grinding up the potassium permanganate, that would only be necessary if he's not dissolving it all in water. 5g per 100ml at room temp is it's solubility.

[@Andreas-gh6is]

For one thing, tesla valves suck at stopping kickback, for another they have a relatively high resistance even in the forward direction... The only way to ensure there is no kickback is to make the pumping pressure higher than the nozzle pressure. That may mean closing off the pump until the reaction has died down a little (like a pulse jet). Or the inlets must be a lot smaller in diameter than the nozzle.

Have followed rocketry since the 1950s. Have two suggestions for cold rocket: 1) Although your injector worked, the reaction was not full. You can see the wave moving back and forth inside the engine, indicating poor/incomplete transition. 2) What you need is a combustion chamber of the right size and shape, fed by an injection plate designed to spray the proper percentages of t-stof and z-stof. You were using them 50/50, but the literature shows that a little bit of t-stof goes a long way. It's more like 10 to 1. 3) Eventually you're going to need a way to pump the fuel. The same stuff was used to power the turbine pumps in the V2 rocket. Print yourself a turbine and use the same fuel for both. 4) Have you ever heard of a rocket nozzle? You're going to need one. It's a nozzle that turns a spray into a roar. Have you ever noticed brass bands? They have bells too. Just for different reasons. But it's all the same. Just a matter of frequency. I love your stuff!

I don’t think H2O2 would benefit the reaction, Just thinking about the reactions in my head, Im 90% sure you would get less out of H2O2 and aluminum frozen than H2O and aluminum frozen

[@zyxwvutsrqponmlkh]

​@@demolition3612 The output of H2O2 decomposition is H2O and liberated O2 Al H2O combustion results in Al2O3 and liberated H2. I would presume H2O2 Al combustion would not have much leftover H2 or O2 if the stoichiometry was matched as those have an affinity for each other.

[@Bavarianscience]

@@zyxwvutsrqponmlkh You can't really freeze H2O2 above like -60°C so preparing and storing that would be kind of a pain already. Also the H2O2 will probably start decomposing due to the high surface area of Al nanopowder present, which would lead into thermal runaway pretty quickly and make it dangerous to work with. Besides that, even at appropriate storage temps like -80°C the peroxide will still slowly decompose, turning the propellant into a porous mass and most certainly lowering it's efficiency.

[@demolition3612]

@@zyxwvutsrqponmlkh I know, however he is using 50% H2O2 50% H2O, and on average the reaction would be like this ; H2O + H2O2 + (2)Al -> (2)H2 + 1 Al2O3 The reaction with 100% H2O goes as fallows, (3)H2O + (2)Al -> (3)H2 + 1 Al2O3 the one with 100% water gets you more hydrogen per aluminum oxide generated, this is negated if you use 100% H2O2, (3)H2O2 + 4Al -> (6)H2 + (2)Al2O3 Also in an Alice rocket it needs to be frozen as a mixture, and the aluminum powder must not be oxidized. H2O2 is just slightly harder to freeze apposed to water.

[@zyxwvutsrqponmlkh]

@@Bavarianscience H2O2 freezes very slightly after water. I have used it to try to fractionally distill 35% peroxide.

Yea like the idea of 3d printing a steam engine an I also recommend making a gas engine with 3 printed metal like the last video.

[@chuckles1808]

I tried that, but the tolerances of printed parts don't meet the standards of gasoline combustion. The term that describes it in action is "catastrophic failure".

[@GuyFawkes911]

You can build two pressure vessels filling them with Hydrogen peroxide and potassium permanganate add compressed air. now you just have to open two valves to feed your rocket engine. An even better way is to coat ceramic beads or a metal mesh with the permanganate. This way you have less water (easier mixing and just one valve) and thus less weight.

[@jeff7798]

You need a check valve,your probly getting back pressure do to the reaction chamber not being isolated from the injectors,that being said DUDE!! That was awesome I love your channel

[@vj.joseph]

You need to revisit this project. Add an aerospike at the end and a rotating detonation chamber inside, use 100% concentrated solution, and a high speed motor for injection and see what happens.

[@ulrichkalber9039]

you need a checkvalve that stops backflow. also : do you know the double syringes that two-component glue comes in? a similar thing might help with putting out the two components in a good relation. then: the steam should contain a lot of oxygen. is it enough to be used in an "afterburner" ?

[@Andreas-gh6is]

A checkvalve would stop the reagents flowing in, also. And it would always trigger while the reaction chamber is under higher pressure than the syringe. if not, you don't need a valve anyway...

[@dmdjt]

@@Andreas-gh6is I think stopping inflow at times is better than backflow. A check valve might not be such a bad idea

[@whatelseison8970]

Peroxide can be used as an oxidizer in its own right. In other words, yes. If you injected fuel into the exhaust stream it would burn strongly and produce thrust if it were followed by a suitable nozzle.

[@The.Heart.Unceasing]

idea : feeding the exhaust of this engine into a hybrid rocket core, using the oxygen from the reaction as the oxidizer, a sort of afterburner if you want (I have no idea if that would work ^^)

[@tvishmaychoudhary69]

No it wound not Do you want to know why?

[@letsflipp]

i think a problem would be the water vapour and it cooling down the oxygen reaction. or it could work and superheat the steam for even better exhaust

[@Hellsong89]

@@letsflipp If you can get past 1000C in the core temp, that water starts to break down to hydrogen and oxygen feeding the reaction even more, but it needs to be pretty high temp. Powerplants use this by feeding wet burnable fuel into furnace so it floats in the air flow and due temps on there mentioned atomic breakdown happens and feeds the fire further, hence why littlebit wet fuel is better, but only if you can get into high temps where this happens, otherwise energy is lost in the heating water further.. though that does expand so there could be net benefit on this.. is it worth the weight and complexity added? Dunno but worth to test i think.

[@The.Heart.Unceasing]

@@tvishmaychoudhary69 why ?

[@STRIKEcorperation]

@@Hellsong89 thermolysis of water is only significant beyond 2000C, and it is endothermic so it wont add any energy to the reaction

You can also make a very interesting contact explosive with the ingredients you have there plus one more which is easily obtainable...back in university we pulled practical jokes on each other frequently using this contact explosive. Great fun!

[@devinrobinson415]

Safety 3rd, love it!! Mike Rowe mentioned the validity of such a thing in all practicality, great video by the way, I knew of silver/peroxide rockets utilizing silver mesh and peroxide I interacting to create thrust, but hadn’t explored the idea in full. Imagine feeding this through a Tesla Turbine and using a massive Tesla Valve to mix the fuel and catalyst feeding the high pressure mix through a Venturi just prior to the inlet of the turbine allowing for an even more atomized mix and further reactive efficiency so the pressure is extreme and consistent upon entry to the Tesla Turbine…….I imagine possibly disastrous pressures and rpm development, but heat would be massively reduced prior to being introduced to the turbine allowing for far more aggressive operation and less deformation and resonance leading to destruction. Coupled to a reduction drive, depending on scale I’d sure be curious about power output values, and this could perhaps allow for a very substantial increase in fuel efficiency. Just a thought. There is a ton of potential energy there and I think with a Valve/Venturi/Turbine/Reduction drive, there could be an interesting powerhouse yet to be built! Keep up the great videos!!!

Proyect idea: A few years ago I remember seeing a lot of potato launchers done with compressed air, you should definitely try a tomato launcher powered by this engine

A "cold" potato/tomato cannon using H2O2 sounds great. Would require a long barrel or a decomp chamber with pressure release valve into the breech, I think.

[@ivankent7437]

Great engineering with that rocket engine. Maybe you should try and ignite the exhaust combustion, maybe it wil give a whole lot more thrust. But be aware that the flame mite flash back so maybe you will need some sort of flash bach mechanism. Good luck.

[@peterelliott3347]

As schoolboy of the 1930's your experiments with potassium permanganate awakened some dormant memories. In those days of pre ball pens we had desks with inkwells. The potassium permanganate was known as Condy's crystals which you could buy dry at the local pharmacist. The effervescent properties were known well and used to play a trick on other classmates by adding a quite small amount to the liquid in the inkwell causing a quite violent reaction. I guess some of those young german kids remembered that too.

[@honkhonk8009]

You were a schoolboy in the 1930s???? Holy fuck You gotta explain more bro. Also i have an inkwell pen from my aunt as a gift. Their still used in countries like Srilanka where its more of a tradition i think.

Add some charcoal and sulfur to your potassium permanganate and you have gunpowder (it's a great replacement for saltpeter). There's also an interesting experiment involving potassium permanganate and a drop of glycerine. Those chemistry sets they used to sell at the toy store usually came with a test tube of potassium permanganate.
