While others have already suggested adding aluminum powder, I would like to expand on why it would be a good addition. Aluminum combustion doesn't create much in the way of gaseous products, but it does create a crap-ton of heat (energy). The reason KNSB propellants are limited to specific impulses of ~120s is their low energy density, not a shortage of gaseous products. Adding something like 10% of fine aluminum powder (with a corresponding increase in KN to accommodate it) should increase the energy density (and thus specific impulse) substantially. The trick is to use a fine enough Al powder that it completes combustion before it exits the nozzle. Sparks are pretty, but they would indicate that the particle size is still too high. An alternative to going to finer Al powder is to use a longer nozzle, which would give the propellant more time to combust before it exits. And no worries about having a few % Fe2O3 in with the Al powder, since there is so much other stuff in the mix you won't see the kind of heat a thermite reaction normally produces.
I watch YT specifically because it is NOT tv. Not only ads, but the shit programming on TV and POZ has infected every single show on TV. There is no such thing as just a 'fun show' anymore. EVERYTHING has political messages embedded within. Even commercials. I cut the cord a long time ago and have never looked back.
I put iron oxide into a motor as a way to give more O2 for the burn. Unfortunately, i put it into an aluminium tube to test it. Epic fail in my front lawn just as the cops drove past. Luckly they saw the funny side.
I once made a rocket made of 1" black pipe filled with R-candy (just firmly packed powder not cooked) and the 1/4" nozzle got clogged (my best guess -- it sure sounded that way) shot the nozzle off and took off a decent sized tree branch (1" or so thick) and kept going... never found it. Safe to say I never did that again. One of those "ok that was really dumb" moments (rare for me). It did fail where I intended it to fail but still.... I have a clip of it in my shotgun shell rocket video if ya don't mind me plugging my self 😁
I call BS the iron oxide wont turn into a thermite reaction as you are implying because its in a aluminum tube. The way thermite works is by the electronegativity of the metals. Rust isn't an oxidizer it just happens to be way down the electronegativity line for the reaction to work. Thermite isn't a standard chemical burn like black powder or kno3 sugar etc its just a very exothermic self sustaining reaction, reason being its products are solids not gasses need for rockets and other things. Adding to much to your "what ever" rocket will just act like an inert chemical like sand. If you are saying the iron oxide reacted with the tube and created a huge flame that the police just happened to be driving by and saw you are lying. Plus its way too coincidal that in the 3 seconds it burnt a cop was driving by your trailer park (see I can sink down to ad hominin attacks)
I'm excited to see what the red iron oxide test looks like on that neat little test rig, considering the difference in burn rate. I hope it wouldnt change throat erosion too much compares to standard knsp.
This is basically what the Hamas terrorist organization is using as rocket propellent. Im not a chemist or bomb maker. I was shocked to find out that you can make rocket fuel out of rusted iron. Jesus Christ 😱
Something that would be really interesting in my opinion is what effect fine (5u) Aluminium or even magnesium (a bit more coarse) would have on burn time and thrust 🤔
when we made napalm in army … there was huge difference in temps when you added aluminium to mix .. and even more when you added red rust ( iron oxide ) to mix.. but the burn rate went up really really rapidly at same time. but those fuels will burn faster when they are in semi closed in.. the heat will make it burn faster and pressure is higher as well..
If you do the Ti again, I might suggest adding more and maybe putting it in a ball mill first. Better effect I think? Also maybe doing the red iron oxide with titanium? I suspect the red stuff burns hotter and that may make for better effect too. And just keep doing what your doing... YT can go wank in a corner...
If you want to add colored flame or effects to your rocket motors you can add these metals.. The larger the chunks the more of a spark that will be thrown out, the finer the grind the more it will just tint the flame. (this comes from a lecture about making fireworks) Red: strontium, white: magnesium (or titanium/phosphorus), yellow: sodium, green: barium (or zinc), blue: copper, purple: potassium, and for gold sparks... Iron. You can also make a blue flame by burning sulfur in a pure oxygen environment but good luck with that in a rocket motor.
It's not necessarily 2 stage and overall would lead to a lesser altitude versus using an actual 2 stage. There's the efficiencies of the different propellants and the thrust to weight ratio.
That would be backward anyway, at higher speeds you need more thrust because of aerodynamic loading. The reason space ships get away with less later is because they are in thin air by then.
Very cool mixtures and nice burn testing! I would say make a slug with magnesium for shits and giggles but it wouldn't be a good propellant to use for a rocket motor. It'd almost certainly melt right through your beautiful aluminum casing causing catastrophic failure. Oh, in progress making a foundry just like the one you made. Made a successful HHO generator. After purge lit about 60 bubbles thinking it couldn't be that bad. Boy was I wrong. Ears were ringing for a couple of minutes and probably set off car alarms in the next county. LOL Good thing I live out in the country. A final note, We've had lots of rain here in CA so, heading to the mountain to dig for gold.Creeks should be flowing nicely. Maybe I'll send you some to add to your elemental collection if you don't already have some. In closing happy to see you are doing your due diligence in propellant testing. I can't wait to see your final rocket design and watch it fly! Thanks for your videos. Take care and be safe. Peace. (^-^)v
it's most definitely not a good direction for youtube. UA-cam should be as far removed from being TV as possible. UA-cam before Google took over was by far better.
Silicone and KMNO4 woulnd not make a good propellant at all. Chlorate based rockets would almost be guaranteed to explode every time and be insanely dangerous to make. Perchlorate is viable, but the ammonium salt is best. In a rocket you want as much of the reaction products as possible to be gas, hence why the ammonium salt is best.
@@ElementalMaker cant find the tests using permanganate/sillicone as a rocket propellant but here is a burning of such composition as fuse: ua-cam.com/video/wkFaz-clHp4/v-deo.html here is explanation about its composition: www.sciencemadness.org/talk/viewthread.php?tid=31890 i was thinking about ammonium perchlorate/PVC and potassium perchlorate/epoxy rocket propellants, my bad... those should be quit interesting and the results should be quite different than the potassium nitrate/sugar one... also molding the grain should be quite easy on those...
I'm kinda curious now what would happen if you mixed in a small amount of thermite mixture instead of just Fe2O3. I don't expect it would be too fantastic or anything, just interesting to see what the addition of aluminum would do there
@@JJayzX there is a type of iron oxide (can't remember which exactly) that is basically Fe2O3+H20 (also unsure about the ratio) and releases the water as steam and the reaction doesn't get quite as hot as "normal" thermite
Wang-jangle!!! There is really nothing better than an excellent reference to another one of my favorite channels!!! Now be sure to put the onion on four hundo! 😂🤣😂🤣
You should try using a hydraulic press to press motors, you can get bigger motors and they are packed more. I use very thick Kraft paper motors and they work fantastically. I have been developing a few ammonium perchlorate fuels as well, if you would like the recipes for those I would love for you to do a video on them. I also really enjoyed your thrust stand video. I made a thrust stand similar to it, without an idea for how i wanted to do it. I wish I had seen your video first! Thanks for the content brother.
Wow that's a long burn compared to the commercial model motors that you buy how high would one pellet that long put a small rocket. Almost out of sight..
What about staggering propellant?. To where the iron oxide mix would give the initial thrust and then the non iron oxide mix for a longer assisted end flight.🤔
Very nice comparison! The iron oxide is indeed very useful. Your BP vids comparing different kinds of carbon were also very interesting. Have you considered carbonizing newspaper, glossy junkmail ads or cardboard boxes as alternative sources of charcoal? I think you'll be surprised should you be tempted to try them.
My science fair project for school last semester was making rocket fuel out of sugar and stump remover. I just ended up using the dry packing method in the end because it was 40° F outside and using my electric grittle was a huge pain. The fuel was never liquid enough to pour into the PVC pipe. I did test a bit of the carmelized stuff and it did burn significantly faster than the other methods. I still have a container of stump remover left so I might try it again in the summer but the mess it made working with the stuff was awful. My digital scale still has the stuff on it.
I'm very glad to hear you were able to do that as a school project! I'm sure many schools out there wouldn't allow for anything involving chemicals and fire. That is awesome 👍
The rust (FeO2) supplies 2 oxygen atoms increasing the burn rate. Which is what the potassium nitrate (KNO3) is already doing and is required for the rocket engine to burn at all. Titanium (Ti) has no oxygen atoms to give and will just burn up. The sparks are cool though. Anything that supplies additional oxygen atoms will increase the burn rate. It would be interesting to try potassium permanganate (KMnO4), Ammonium Nitrate (NH4NO3), or even Aluminum Oxide (AlO) and see what happens.
Not quite ad free, I still do one or two just so I don't go broke making these videos. But some day hopefully my patreon will replace the ad revenue. UA-cam wants creators to litter videos with ads. It's crazy.
I'd be sketched out by putting a composition with sulfur on the heater for melting. Sulfur is more reactive than Fe2O3, so you might get spontaneous ignition.
I totally agree with you concerning the ad whores @ UA-cam. Watched a video just this morning by a channel that I have been subscribed to for over three years. The video was 8:35. Opened with a two minute ad from the Trumper bragging about being the only truly great president USA has ever had. Midway of the 'real' content (and mid-sentence also, I might add) was an anti-abortion ad that went for 45 seconds. For the grand finalé, an ad OVER 6 minutes long about women's health and cancer treatment options. Can anybody enlighten me as to why any of those ads are targeted towards a blacksmithing community. Thumbs up in support of the 'Ban UA-cam Ads Movement' . 👍👍👍🙈🙉🙊👍👍👍
That was very cool Now the question is what can be added to make an even more powerful burn rate. This just fantastic stuff to learn, or forgotten info from science class way back in the day..keep it up love this stuff
@@JJayzX You aren't going to get a thermite reaction when the iron oxide and aluminum are only ~10% of the overall mix. Especially with something like KN to serve as an oxygen source, the Al will consume the KN well before it gets to work on the Fe2O3.
Burning the mixtures in the open air do not tell you much about their utility as a propellant. A trivial example is BP burned unconfined and when confined - massive difference. If I recall correctly, KN is not used with Al as a propellant because the pressure exponent is too great.
You should come to the MDRA launch in the beginning of March. I'll hopefully be bringing a few sugar motors that have Al and Mg in then for a higher isp
SRBs used aluminium in the propellant mix, would that have an effect on this kind of propellant? And how about a mix of iron dioxide and aluminium? (Somebody already mentioned thermite)
Higher temperatures would most likely be required to use aluminum over iron. Also mixing them for thermite would simply just destroy the rocket and produce little thrust.
Adding something like 10% fine aluminum powder should increase the specific impulse of the rocket. Even with a few percent iron oxide on top of that, they would be too dilute to get any kind of proper thermite reaction going.
what about having the first half of the slug catalysed but the top with slower burn, since the rocket will be much lighter once it burns the first half, resulting in flatter acceleration?
Would manganese dioxide have a similar effect? it is a mild oxidizer and should give off a bit of oxygen at 500c and turn into Mn2O3, the fumes would be nasty from Mn2O3 and also, what about MnO2 battery paste?
My uncle was on a quest in his younger day to make model rocket fuel from caramel candy and Salt Peter. Grandpa was afraid he was going to burn down or blow up the house.
I prefer it simply for its significantly lower melting point and easier workability than other sugar fuels. It does have less overall energy content though, so it's a bit of a trade. Safer and easier to use, but less power.
Just a word or warning. Sparky motors = grass fires = a bad day. I have a 15 year old pair of shoes that still smells like smoke because a black powder motor started a grass fire on the local HPR club's flying field.
Can you please make a vid about adding different metal dusts to rocket propellant? You've already done this one with iron oxide but I mean with Al, Cu, Mg, Al-Mg alloy.... Basically to see if it can colour the flame to any point where as the rocket rises a green or white flame can be seen.
With this type of propellant there is no way to color the flame, as it's actually just a smoke trail. Composite AP propellants can easily be colored though, and I will be doing videos on that shortly 👍
ElementalMaker I would like to see a KNSB rocket fuel grain made with 2% Manganese dioxide which is used to catalyze oxygen release in some potassium in the laboratory methods for oxygen production.
Yo, I'd be curious about copper oxychloride as a catalyst. I've used it for gerbs as you can see on my channel. Would love to see if it works better/worse than FE2O3.
So, out of curiosity, what would happen if you loaded an engine so the first portion of the burn was iron oxide and say about half way through it went to normal slow burning propellant? The iron oxide should get the rocket moving faster initially which would overcome at rest inertia and then the slow propellant would cause a longer burn for possibly greater apogee........what do you think?
That's definitely doable, but due to the larger size of the motor required and the mass that goes with that, it's typically more effective to have two stages. One for lift off, and then that is ejected and a second motor called the sustainer is ignited.
So where was the Arduino test stand Tests you promised way back long ago? Wouldn't Aluminium powder be a better test additive than Titanium that doesn't affect burn rate ? How about a BP test?
@@JJayzX Great show of sparks, in broad daylight! It was spectacular (NOT). I saw 6 or 7 spots. Months ago He said he was going to do thrust measurement tests on the Arduino test gizmo he made of different mixtures to evaluate the fuel types. This video was a waste of time, it was a just a quickly made video with little to no effort to fill the gaps between his interesting Vids!

@@KifoMilele24 yes but with only a few percents ?!

Makes sense that adding an oxide to your propellent would make it burn more violently.
Is it supposed to be alu powder and rust in the knsb test? If it burns, obviously it will be a hugh kick.
aluminum and iron makes thermite which is mainly a fast high heat reaction. you need large amounts of expansive gas for thrust.

it is a mild oxidizer and should give off a bit of oxygen at 500c and turn into Mn2O3, the fumes would be nasty from Mn2O3 and also, what about MnO2 battery paste?
Great question, I'd think MnO2 probably would act as a good burn rate catalyst. Might be a fun test!
@@ElementalMaker Maybe
That might be something I should try one day, that is if I can get a chlorate/perchlorate cell running
Late to the party, but what makes something a good burn rate catalyst?
Try copperoxide as well. Should have stronger reaction then iron.

I would really like to see this with aluminium powder added
Could you mix the red iron oxide with the titanium sponge?
did you try iron (lll) oxide? it's the black iron oxide, it will maybe burn even faster
Could you make propellant using ammonium based oxygen?
Sweet .it looks like youre going to try the clear hybrid engine
ooo thank you so much! I recently asked this question, idk if this video is about my comment but I'll pretend it is. thanks!
Could you do a video on the difference between deflagration and thermal runaway?
the titanium one was awesome I'd love to see you do that in a three grain motor with a bit more
Would copper powder make a green or blue flame?
You can use copper oxychloride instead of rust and it will make it blueish
I really enjoy your content.
My uncle was on a quest in his younger day to make model rocket fuel from caramel candy and Salt Peter. Grandpa was afraid he was going to burn down or blow up the house.
any particular reason for choosing KNSB over KNSU or KNDX?
I prefer it simply for its significantly lower melting point and easier workability than other sugar fuels. It does have less overall energy content though, so it's a bit of a trade. Safer and easier to use, but less power.
Just a word or warning. Sparky motors = grass fires = a bad day.
I have a 15 year old pair of shoes that still smells like smoke because a black powder motor started a grass fire on the local HPR club's flying field.
Can you please make a vid about adding different metal dusts to rocket propellant? You've already done this one with iron oxide but I mean with Al, Cu, Mg, Al-Mg alloy.... Basically to see if it can colour the flame to any point where as the rocket rises a green or white flame can be seen.
With this type of propellant there is no way to color the flame, as it's actually just a smoke trail. Composite AP propellants can easily be colored though, and I will be doing videos on that shortly 👍
So you use the Hairy and rusty nuts and get a better thrust? well that just great I have ordered 4kg. Great video again. 😁👍
Never seen a finer wangjangle technique

immediately looked at that nuts.com bag and laughed... I love this guy
ElementalMaker I would like to see a KNSB rocket fuel grain made with 2% Manganese dioxide which is used to catalyze oxygen release in some potassium in the laboratory methods for oxygen production.

Truly appreciate your support 👍
@@ElementalMaker of course man I appreciate your content
you should try and add some iodine to the mix with ti sponge
There is a reason we don't add Iodine to rocket motors. You'll either make an explosive or it will be so sensitive you'll blow it up just mixing it
@@BinaryMachinist LOL i didnt know that i just thought it would be a cool visual effect
Yo, I'd be curious about copper oxychloride as a catalyst. I've used it for gerbs as you can see on my channel. Would love to see if it works better/worse than FE2O3.
What happened to the fourth one? The one aluminium oxide in it? Good videos keep it up!
Aluminum oxide wouldn't do anything, except perhaps slow down burn rate.
How does this compare to sugar rockets?
This type of propellant is considered a sugar rocket. It has about 60% the impulse of sucrose based rcandy though.
So, out of curiosity, what would happen if you loaded an engine so the first portion of the burn was iron oxide and say about half way through it went to normal slow burning propellant? The iron oxide should get the rocket moving faster initially which would overcome at rest inertia and then the slow propellant would cause a longer burn for possibly greater apogee........what do you think?
That's definitely doable, but due to the larger size of the motor required and the mass that goes with that, it's typically more effective to have two stages. One for lift off, and then that is ejected and a second motor called the sustainer is ignited.
So where was the Arduino test stand Tests you promised way back long ago? Wouldn't Aluminium powder be a better test additive than Titanium that doesn't affect burn rate ? How about a BP test?
The titanium was just for show, to create sparks in exhaust.
@@JJayzX Great show of sparks, in broad daylight! It was spectacular (NOT). I saw 6 or 7 spots. Months ago He said he was going to do thrust measurement tests on the Arduino test gizmo he made of different mixtures to evaluate the fuel types. This video was a waste of time, it was a just a quickly made video with little to no effort to fill the gaps between his interesting Vids!
what is brown bottle??
Timestamp?
Tripp is that you? this is chip. If not , you sound, and have very similar expressions to a great friend of mine I haven't seen in years
"premature, but that's my style." 🤣
Great video
that looks like a proto hybrid motor at 7:43 :)
I have no idea what your talking about. You must be seeing things.
I'm glad you like rockets I enjoy some as well but your channel was cooler when you build stuff and used elements
Iron oxide is one additive and powdered mg or al is too cuo give you deep blue flames
Love this channel
Hey! Just wanted to make sure everything is OK, we miss you and haven't heard from you in a few weeks!
All is good! Had a couple big construction projects that I needed to crank out, but got a video coming tomorrow!
Great vid
"My ram rod ain't workin'.... there are pills for that!'
Waiting for motor tests!
