So.... you still looking for more concentrated peroxide ?? 👀
You bet your ass I am 🤩
@@integza xdd
Isnt there something better than peroxide... maybe something yellow?

@@geekswithfeet9137 haha yeah all theoretical of course. Haha yeah haha just having a laugh , no need to tag ASIO haha (please)
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.
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...
Maybe for the pumps a stepper motor and leadscrew on a syringe might work
Probobly easier with a pressure tank. Its not much displacement needed
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?
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.
Saudações portuguesas, ó grande enginheiro!
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.
Dude the quality of the editing of this is amazing. And the unobstructed confidence when delivering lines, even during the zoom ins, is legendary.
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
Redsigning the injector for higher pressures so that the catalyst and catalyzer can be atomized before mixing would help.
I think the reason his test at the beginning didn’t work so well was because of the lack of surface area.
Anjay
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.
@@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.
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.
Yes and maybe CO2 canisters instead of air pressure. Although with the speed of the reaction it might be difficult to control.
@@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.
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
Pretty sure you guys are describing a super soaker
@@larryfigerbutz7184 a super soaker on steroids crack and meth because the rocket engine will have significantly higher pressures to deal with but yes same basic concept

I first noticed this on the second watch because I didn't know PPAP when I first saw this video.
I don't know if Integza actually intended this reference or if I misinterpreted it...
Careful when mixing those combinations. Surely you have heard of the German pilot who was fatally burned with that stuff due to a leak while his craft was being fueled. Really like your content and style of delivery.
What I heard was that the pilot wasn't burned so much as dissolved. Neither sounds desirable.
I love how he didn't even want to talk about a hypergolic rocket engines.
Scary stuff.
He kinda does, H202 is hypergolic in some reactions (the concentrations the Nazi's used in the 163, for instance). Generally though, hypergolic fuels are insanely toxic. As are some monopropellants
Hydrazine is an example. It's one of the byproducts of mixing bleach and ammonia, to put that in perspective.
"Well, it's all the same dangers of monopropellent rockets but it's also made out of *EXPLOSIVE POISON!* :D"
The Luftwaffe found that out really quickly. Fuel that melts the pilot and explodes if the ground crew sneezes really isn’t a winner. Particularly if you are meant to attack things that shoot back with lots of .50 caliber machine guns.
I WANT TO KNOW THE STORY BEHIND THIS THOUGH!!!
@@frogz Just search up the ME 163 Documentary. Super Scary Stuff. I think there were more pilot deaths due to them literally exploding and being burned (Or better put, eaten) alive on the runway, than to enemy attack.
Integza great video. When I was a kid I made a compressed air and water rocket for a science project. I bet you could make a powerful compressed-air water rocket. Thanks and keep em coming great work. Peace.
OMG i have found the best channel on RUclips! This is amazing! This guys incredible! Keep it up bud! Amazing work!
Integza: "For the first time in history, something good came out of Nazi research"
NASA: Am I A Joke To You???
NASAs rockets are all derived from the v2 a nazi rocket from WW2
@TASC Aerospace Its not nice to say that.
Saturn V wouldn't have happened without Werner Von Braun and Operation Paperclip! So yes something good came out of German scientific talent not from Nazi research. Braun initially approached Nazi ministry to fund his space research program and they put him into rocketry development for military projects. Not saying that he isn't culpable, but at least his initial intention wasn't to build rockets for Wermacht
Don't forget Yugoslavia 🤣 en.m.wikipedia.org/wiki/Houston,_We_Have_a_Problem!_(film)
@@tinkukuty1232 I definitely agree with your distinction between German scientific talent and the unfortunate way it was put to use by the Nazis.
I don't think it's fair to say rockets as sophisticated as Saturn V wouldn't have happened though. Reaction engines date back to antiquity, and as you say, German engineers (as well as engineers the world over) were certainly up to the task. It was just a matter of time and the will to do it.
It's just too bad people can almost never see fit to muster that level of will unless it's in service of a military agenda in one way or another.
There's something so gratifying about watching someone who clearly isn't mentally prepared for the reaction they are initiating.
Oh yeah? tell Robert Oppenheimer that.
@@JohnnyWednesday I think everyone involved in **that** project was quite mentally prepared for what they were doing, even if they didn't fully appreciate all the implications at the time.
In chem 2, we made Nitrogen tri iodide (NI3) and one of the people in back “made too much” so she threw three filters SOAKED in NI3 in the trash next to their bench. 10 mins later we start hearing popping and snapping from the bag as her trash bin started giving off brown purple vapor and calmly exploding.

Great video, just a note: at the beginning you are mixing up in the videos two different aircrafts: the HE-176 and the ME-163. Just saw the latter one in "Deutsches Museum" in Munich/Germany. The ME-163 came after the HE-167 and was actually in use even though with little effect.
I did a thing is a really funny channel to and also a very well put together show like this.
I get a lot of enjoyment out of that channel and this one like others that are similar.
Again I'm surprised I'm just learning about your channel just recently.
Thank you for the time you all pt into this for us.
I personally very much appreciate the time I get to smile and watch videos.
It would be interesting to use a FLIR and see how much heat the steam produces, in real time, plus see the primary catalyst points. Good job brother!
What material did you use for the sla resin printing?
that is an awesome idea
I personally prefer the Trijicon REAP-IR... I'll see myself out.

I see a Tesla valve coming in handy in preventing the flow back pressure to the syringe! That would be in true Integza style!

Love ur stuff bro
Make an ALICE rocket, but using hydrogen peroxide instead of water.
en.wikipedia.org/wiki/ALICE_%28propellant%29
[update]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.
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
@@demolition3612 The output of H2O2 decomposition is H2O and liberated O2

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

If you want to avoid the drama of solid catalyst beds, spraying a high pressure jet of KMnO4(aq) against a jet of H2O2 would probably be the easiest way to get fast mixing.
When I was 12 i made a lot of firecrackers mixing potassium permarganate (марганцовка) with aluminum powder (there was a lot of it, used as paint in soviet times) and some matches heads for primer , when the mix is right you get nice big explosion shining like supernova, when it’s wrong boom is much smaller but it shoots permarganate crystals in all directions they getting stuck in the clothes and when you wash it magic happens :all of your clothes are covered with 5mm holes and/or pink spots …) , you also can make rocket from that mix but it can blow up)
I'm really amazed that such an energetic reaction produces so little heat.
Love your videos!

"All great science end in explosions!" Andy Weir
Testing isn’t finished until the prototype is destroyed.
Chemistry is so cool that we're still blown away by stuff from the 40's. Integza, why not use a tesla valve to feed the fuel evenly to the rocket chamber and prevent the kickback? I think you could still use the syringes without them exploding on your moustache.
Ahh bringing back Tesla solid state valves I like it
This comment needs more likes!
Genius idea
I was thinking the same thing!
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.
Nice exhibit A.
congrats.
keep up the good work.
I can't subscribe to your patron but your content is good enough to where I'd be willing to go through to ads and whole video so you get money
I have a stupid idea with some potential, that largely defeats the purpose of this engine
Unless I'm stupid, the breakdown of hydrogen peroxide makes a good amount of oxygen gas
Why not add some fuel to the catalyst, to react with the oxygen, generating more heat and thrust?
If you use ethanol as fuel Tada now u got a V2
@@rh9909 add tablespoon of gyroscopic inertial GNC, a pinch of high explosive and a empty kitchen paper roll... A bit of super glue and now you are ready to send your homemade V2 over the British channel!!! 🤣
That would get very hot though, and burn 3D printed rocket parts...
@@rh9909 No the V2 used kerosene and LOX. The peroxide expansion just ran the turbo pump.
actually, the first jet pack was made using this same concept. why not make a jetpack with these rockets.. if i remember correctly, the design had used a pipe from the expansion chamber to feed into the supply containers, and a variable restriction valve in that feed tube to control it. as more pressure is built up into the reaction chamber, it back feeds to the supply chambers forcing more into the reaction chamber.
Material with highest heat resistant you could buy is graphite.... I dont find anything for 3D printing, but maybe you could use graphite rod for critical parts, shaping with lathe and combinate with 3d printed metal parts.

Imagine being integza's neighbor across the street and constantly having a portuguese man launching rockets and tomatoes in your direction, and destroying your tomato garden. Video Idea: build small 3d-printable rockets with a compartment for the permanganate and the peroxide and make it so when you shake it, it mixes them, causing them to launch and fly away.
tfw your neighbour sprays the entire neighbourhood with a mixture of manganese dioxide and permanganate, and every single plant dies
I wish smart people lived across the street lol
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! Did you say you live in Texas? I also settled west of the Pecos, where there is no God.
It's very odd, but I'm 69 years old, and you remind me of my father. He was always looking at me as if to say, "You could not be the product of my loins." I was, and now have all of his odd twitches and proclivities myself. Thanks.
Peace,
as a german, its called "stoff" not "stof"
🙄@@1ue999
Pretty sure he's Portuguese.
He said "You could not be the product of my loins."? I know this man! Your father was Buford T. Justice.
If I'm not mistaken, the "rocket packs" developed last century were H²O² powered also but they used a platinum "sponge"/mesh as the catalyst. The nozzles got extremely hot in the process.
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.
good job... you give us very interesting information
Incorporate Tesla's one way valve on both inputs to prevent blow back on the injectors. This should also help to get all the pressure to exit out the nozzle end of the rocket.
Oh I can see that possibly working

4:22 "... I need to find another solution..." Classic chemistry humor there.
12:12 Given that your thumbs are holding the syringes in place, that is a measure of how much pressure the rocket is (currently) generating; viz, the rate of reaction will need to be increased by several orders of magnitude, probably to almost "explosive" levels.
Needs baffling to prevent unreacted fuel mix from being forced out the nozzle... would gain many X efficiency... but would likely over pressure the device.. Thanks for the very entertaining videos!
Landlord Note: Add to tenant contract “No building or testing rocket engines or chemistry experiments on the premises.”
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" ?
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...
@@Andreas-gh6is I think stopping inflow at times is better than backflow. A check valve might not be such a bad idea
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.
I will note, that a few successful ME163 flights occurred, with confirmed kills on allied bombers; who didn't understand what the hell was attacking them, out of nowhere, with no sound.
that said, the design has a higher body-count of pilots, than enemy airmen. Turns out, flesh and 90% Hydrogen Peroxide do not mix well.
I can imagine that death being very horrific
plus the design of it made it incredibly hard to control in flight
And the operational range was rather poor.
High Test Peroxide doesn't mix well with ANYTHING. It even has a tendency to spontaneously explode. Some countries have used it as a torpedo propellant, but they tend to eventually have catastrophic accidents. It's also used in some systems in modern rocketry, usually reaction control thrusters.
Ah yes, not sure if you would even want to survive that if you got showered within a 90% hydrogenperoxide cloud. must be a great feeling when it covers the inside of your lungs
So good to see I Did A Thing pop up on here
Dhanyabad to you also! You teach us a lot!!! Love from India...❤❤❤
I feel like you could i use a whole lot less permangante since it's a catalyst. It might make the output stream more consistent. Or even better find some way to hold it stationary instead of in a fluid? Like a mesh or honeycomb that the peroxide gets shot through. I have no idea how that would work but you're the engineer.
Platinum mesh would be ideal iirc. Probably some cheaper mesh that could be used tho.
@@zechsblack5891 hmmm, that break instantly when the platnium oxidices (burns)
So let's imagine he dipped a half cured resin print in it. he would have to change the nozzle and make it use the whole area and there are reasons he's avoiding the middle. But then those are replaceable fuel cells and a chance it doesn't stay on
I think your thinking of a hybrid rocket fuel grain

"no tomatoes were harmed in the making of this video"
-everyone disliked that
I would like to see the thrust of your rocket engines tested in their ability to squish a tomato, or at least how damaged they would be if you put them in the direction of the exhaust.
what a great project. you need 2 tanks that could be pressurized, check valves, mixture valves and throttle valves. you can then control the mixing ratio of the liquids to increase the chamber pressure or press the Permanganate into a block in a cup in the pressure chamber and spray peroxide on to it. that way the peroxide react with the correct amount of permanganate to optimize the reaction. anyway again great project.
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!!!
Apologies for typos, thumbs weren’t designed for phones!
I think a cool video would be using the Tesla “valve” in a water pump, it would be interesting to see how fast water could flow and if any pressure was able to be made.
My THOUGHT exactli
Not a bad idea to control back pressure.
Pitch it to an engineer thats what i do.
It's already being done. To genius to not be utilized for awhile now.
Came to suggest using a one-way valve for back pressure regulation at fuel storages... These might be worth looking into simultanously!
I think that some thrust is escaping at the syringes making them harder to pump which is bad
A one way valve should work
This is where your old TESLA value would work
That's not how thrust works. It doesn't matter if the pressure pushes against a valve or the syringes, the thrust would be the same. A valve would not have any effect, especially a Tesla one.
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

Add some charcoal and sulfur to your potassium permanganate and you have gunpowder (it's a great replacement for saltpeter).

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!
I think you may need to dilute your permanganate a wee bit more. Adding a pump and check valve with a bit of a flow controller can give you controlled thrust
You should make the "combustion chamber" more compact

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.

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.

Better a hho potato canon
I know I’m late, but have you considered putting a bellnossil at the end of that?
If you can get more of the “thrust” facing directly backwards would give you more efficient thrust
Integza the mechanic of the pump it's actually pretty simple first you drill a hole in the side but litle back not on the front, second cut the handle seal the back glue a hose to the hole conect it to an air pump release the presure on the hole you made
Advice: RUclips does NOT like swastikas in a preview image.
Swastika as in the Hindu symbol, translating to wellbeing?
You're both right!
@@Potato_Major “plastered all over” what, 2?
@@Potato_Major yes but the symbol is originally a Hindu one, and the word is Sanskrit(?) So it isn't an intrisically nazi symbol so you can't really have a blanket ban on it. It would depend on context. Not that I'd expect RUclips moderators to display awareness of such a concept.
But that’s not what it’s being used here as. There is nothing Hindu about a rocket that’s designed to blow people up and help the Nazis take over the world. Check your context.
There are some hydrogen peroxide rocket cars. They are totally insane. They also use a fancy ceramic catalysts
I love you crazy portagese experimenters logic
Safety third is a great burner phrase but still, safety first because you are a great person who makes us happy.
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.
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.
Project Idea: Maybe try to make a "professional" water rocket before building a chemical one, something that would fly hundreds of meters, you could even test it with an aerospike nozzle (or hydrospike?)!. I think it would help you develop the final version of a chemical rocket.
čao
I recall a Salt Flats speed record car powered by peroxide and if I remember correctly the catalyst was nickel silver mesh wire. Worked well. Check it out
you can use presure from the trus chamber to actuate the embols of the seringes
I think it would be suuuper cool to se a part 2 of this video. A video where you upgrade the nozzle and syringes and where you measure the force generated by the rocket!!
Thank you, Intzega!!
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 ^^)
No it wound not
Do you want to know why?
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
@@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.
@@tvishmaychoudhary69 why ?
@@Hellsong89 thermolysis of water is only significant beyond 2000C, and it is endothermic so it wont add any energy to the reaction
For optimisation you could make the nozzle Exit even smaller. You want the exhaust to come out as straight as possible. In your case, the exhaust formed a cone, which means that your exhaust Gas preassure was to high
Would love to see that engine power an actual rocket, the quest to get to space!
Would love to see a piston or rotary engine made with these substances
check out 'peroxide turbines'.
I bet you own a Flintstone car. You love oldfashion lack of engineering. Piston engines use 70% of the fuel to heat the air. Exhaust is bloody hot and all that energy is wasted. And nobody has done anything the last 50 years, to change that. No, homo sapiens is not half as intelligent as he thinks he is. Piston engines? It is junk! Reliable maybe, still junk!
@@voornaam3191 reliable by nature is not junk. Inefficient, yes, but junk is by nature inefficient.
As for heat output, don't even get me started on turbine heat output! Efficient, sure, but any degree of lateral runout on a bearing will catastrophically destroy the turbine.
@@voornaam3191 “guys look at me I’m so futuristic please give me the attention I never received from my parents”
@@voornaam3191 bro chill out. It's just an idea, mr "I live in the future and love being a jerk". Just cuz it's old or doesn't have a lot of engineering doesn't mean its junk. Go get attention from somewhere else
Main idea for next video: try again with silver as a catalyst, but this time try to make a different shape (in X-15 plane, they used silver in a shape of a sieve (hope it was translated correctly), through which the peroxide was passed (hope that translated correctly as well));
Another idea: try and make the most efficient possible bell/aerospike nozzle for your rocket (a little bit of fluid mechanics).
Nice video btw, I always love modern interpretations of old ideas!
How did you manage to avoid peroxide burns on your arms when that syringe blew back? When I am working with high strength H2O2 I always manage to get burned by a splash somewhere. Guess you learned about the purple permanganate stains also. I'm really impressed by your 3-D printed rocket engine. Keep up the good work and stay safe.
dude i only have 12% and after doing some experiments my fingers were pretty much white. thankfully running underwater and rubbing helped
I would be very interested in material strength tests for projects like this and other combustion chamers. Potential for chemical engines is unlimited.
It may help to create a “solid propellant” style lining with the KMnO4 and have the H2O2 flow through it but I would imagen the stream velocity through the lining would have to be somewhat high in order to keep the thrust in one direction ish
This would not work as well: It's an issue of surface area. As a liquid spray the surface area is massively higher then it could be as a lining. That being said, I'm pretty sure Integza is using a massive excess of Permanganate - could use a LOT less.
@@crocosnz3322 re: permanganate, true! Also check valves in the injection lines will be key!
i'd like to see much more with this engine type, planes, rockets, steam engines whatever you feel like building the most, i'll certainly love to watch it!
potassium permanganate is my favourite oxidiser, nice to see it. Downside being things turning purple...maybe not a downside :)
The fact that he didn't use a bell nozzle ruffles my jimmies.
Hey Integza
I was wondering if you could show a thermal image of the rocket in action so we can see how much heat is generated as it'd be incredibly interesting to see.
See just how "cold" it really is
Curious, when designing the nozzle do you just pick a geometry that looks good or do you actually use the equations to design a proper nozzle? Because I think if you continue with this project you should definitely make a proper one!
@@smashinbedrock4903 oh trust me I know. Got an entire degree on it. The mass flow for the hand pump would be tricky but if he automated like he wanted too then its all very doable. And some approximations are always okay lol
If you have watched him you know he doesn't do engineering.
You did all this rant just to bring up your fancy degree on equations to proper nozzle. Clearly because you thing you are better than us.
I really hope you have the distinguishing moustache required to flex like that around here boy.
@@saooran7364 My mustache can't compete with Integzas that's for sure! Then again no ones can. Just love to help him put a nozzle together if he wants since it can be hard!
@@jaredsmythe4649 You sounded a little too snub-nozzled, but you are a fine lad after all.
Use engine fuel pump, and PD style injectors and you can control those with small microcontroller to get decent fuel back pressure tolerance :)
Grate video!
