Adding aluminium powder to Sugar rocket fuel- Static tests

[Lagger111]

please explain to me how do you turn it on.... sorry for my bad english :P

[donperry1]

Can you try a mixture for me?

it's 63/32/4/1

That's kno3/sugar/aluminum/red iron oxide

the 1% RIO supposed to stabilize the burn. I'd be VERY HAPPY if you try this, please

[donperry1]

@donperry1 or whatever mixture, just add Red iron oxide to stabilize it. Aluminum loves RIO

[CactusJoex71]

Follow some comments, but do a dynamic test....thermite shall rain down upon thee!!

[Rydlis]

add very small amount of titanium ;-) it will not change burning of KNO3+sucrose and it adds nice white tail :)

[tgmeow]

PUT IRON OXIDE INTO IT!!!

[sadeyedangel]

Very cool. Did you put iron oxide in it too?

[hilers72652]

the one at 1 minute reminded me of those strobe things

[14Flolo]

1:00 Strobe Rocket!

[donperry1]

Have you tried using a higher KN ratio? lower KN usually results in chuffing in any fuel grain type,. Use a longer pipe or smaller hole and let us see plz :)

[donperry1]

Red iron oxide might stabilized that aluminum sputter :)

[CrossoverManiac]

How you measured Isp for your rocket?

[rmoss15]

@CrossoverManiac I don't believe I stated the Isp of these rockets as I didn't measure the thrust, but it is found by dividing the effective exhaust velocity by 9.8 which can be found by dividing the total impulse of the rocket by the mass of the fuel in kilograms.

[DavidRothe]

I can´t imagine these PVC-pipes holding that pressure - did you put a stell casing or so in it? Looks like very high pressure in there.

[rmoss15]

@DavidRothe The PVC would not be able to handle much more than 400 - 500 PSI for any extended period of time but the casing can handle that pressure since it is only acting on it for a few seconds.

[cr76802]

Try a aluminum powered/ iron oxide "thermit as your core and the sugar sulfur and iron as you outer core. Should provide a nice steady heat source. Also How ever drops of molting iron would ruin someones day but be cool to see flying out a rocket

[imatelly]

yeah get rid of the aluminum and the sulfur,and go with iron oxside,or try iron oxside and aluminum

[Mr71seventyone1]

how to ignite it

[gettingahandle]

Keep experimenting... you will get it right on the 5,674th go.

[schoorl200]

I think after the Anders Breivik case, anybody buying KNO3 and aluminumpowder will be shot through the head, just out of precaution

[tbarius2]

1:28 kinda make me shit myself

[TLOZTPfan]

Tests #s 5 and 1 seem to be the most viable fuels in my opinion. Try testing each material (very carefully) by itself to identify the positives and negatives of each e.g., stability, visibility, strength etc.. I agree that sulfur seems to be the problem with 2-4, and the glucose syrup might be why #5 didn't have a very visible flame. ( I'm 13 btw :) )

[caseydalen]

Add an oxidizer, perchlorate would do nicely, and some red iron oxide powder

[roarkld]

Would rusting the Al add O2 to the fire?

[eamonshortftw]

which would you recommend and are the part compositions by weight/?

[ScizzayJ]

@marlboroman67213 sulphur and sugar cause a solid residue that doesnt escape the rocket, it causes pulses as gas inside generates then expels removing the residue but it soon biulds back up, if magnesium or magnalium were used with no sulphur it may give off a spark continuously as these two metals/alloys oxidize more easily, magnalium should also make it crackle slighlty which would add good effect!

[ScizzayJ]

Ive tried compositions before with sugar and sulphur and the problem is that it makes a hard ash/residue that blocks the nozzle of the rocket/fountain, if you want to achieve a bright spark trail this hard blockage can stop the visible flame, so it may be worth trying magnalium powder or magnesium on its own as it is more reactive and shouldnt need the presence of sulphur to achieve a bright spark

[HunterisaKiller99]

Use gasoline

[leonidhaimov]

1:28 was awesome! Full of power!

[yoyojoe618]

I'm trying to make a rocket with that stuff... It might actually make it into space!!!

[BankaiIchigo12345]

You keep burning them out the side lol.

[crapbag1997]

impresive looks like a cored rocket

[UTubeisSHIT523441]

on the last test the aluminium didn't even burn.

[jaffabend]

I really like these type of vdeos. How on earth do you avoid getting arrested doing this in the (boring, nanny state, over legislated) UK? May I suggest running your tests with the samples on a spring balance to get feedback of the forces generated?

[kludge000]

have you done chemical balance equations to see how clean your burn is? when I add some of your fuel percentages up I get more 100%!? and are the percentages by weight or volume?

[kludge000]

have you done chemical balance equations to see how clean your burn is?

[galileo93]

Very nice rocket fuel!

I assume you didn't cocked it on the pan right? just mixed to powders right?

[sliderulex]

What you need to do is list ALL the chemicals used. Then a chemist can calculate the balanced reaction and supply thermodynamic calculations showing how much of each compound/element to add and the volume of gases liberated from the reaction. Not only will your reaction work best from a balanced equation, but the performance of the rocket fuel will be maximized and you will also know how much thrust you can expect knowing the delta H from thermodynamic calculations.

[o0Jumper560o]

I like the second one, i have aluminium powder that is a poor mesh size and i'm going to add it to some black powder to see if i can get something like this. I might also try the formula you have for it but i couldn't really understand it because you didn't you percentages for all of them, and if you did it didn't add up to 100. i think my aluminum is about 100 or less, i'm not very sure how to scale them.

[airsoftbattlefield1]

1:04 You made a fireball

[Morrigi192]

@airsoftbattlefield1 Also a nice smoke bomb

[airsoftbattlefield1]

@Morrigi192 lol

[UTubeisSHIT523441]

Your casing should be made from hard paperboard, since when ignited it forms a layer of carbon inside the tube which is very heat resistant. Thats why the tubes on model-rocket motors are made from hard-paperboard. The Soviets even use the paper on their shuttles, to protect the inner metal from oxidizing/melting during reentry.

[ambrose79605]

have you tried adding 2%or so iron oxide to the mix.

[eamonshortftw]

wow did u ball mill it or something cause when i mixed it it dosent go well, i always fail no matter how expensive mats i buy

[eamonshortftw]

hey man love to vid epic. the surcrose, is that in syrup form if not where do u get it, secondly what is the coposition of hte first one if u added 15% al dose that mean u make 100 grms then add 15 grms Al?

[rmoss15]

@eamonshortftw Yes, that was to illustrate the poor combustion of the extremely fuel rich propellant as it had a lot of carbon and aluminium residue in the motor casing after the burn.

[donperry1]

Try 70K, 23Char,5SU,2%Red iron oxide

[prefuseAsa]

make me a car

[Bombermanos]

If you want to compress powder mix that has Al, you need to have it in fine powder and smash it extra hard to make the fuel grain burn stable. Good luck!

[schabanow]

Guys, don't be silly, start LEARNING with nakka-rocketry net

Take care!

[schabanow]

Why your MOTORS burn SO slow??? Are they MOTORS or just test sample without any Kn? Do you MELT white thermostable sugar or RECRYSTALL ordinary one from water solution? Do your grains consist hollow core or not?

Normal hollow cored sugar propellant motor work - is just a little prolonged FLASH (0,2 .. 0,5 sec), not BURNING as you show...

I suspect here we have just lack of basic knowledge...

[Michaelamosh]

aluminum sulfur and kno3 is a flash powder id use another oxidizer

[Jakes720s]

Were you lighting that off with a battery? Lol

[mrnewagemotor]

That last one looked like a good steady burn. I would work on a better combination of that one. It looks like it could really get there.

[cantescape1987]

You said 400 Mesh right but i have <2 micron GD Al do you think it's save enough to use this?

[rmoss15]

@cantescape1987 Yes. I have tried using 2 micron aluminium but it is very hard to mix in because of its nanoparticle properties and its tendency to blow away when the fuel it turned over, the flame from 2 micron aluminium is not as bright as the 400 mesh and actually lowers specific impulse. Anyway 2 micron is best used in flash powder. ;)

[kobasica]

1lbs of thrust or 2?

[TheMultiPyromane]

 really helpful! gerat job;-)

[Arctica14]

The second sounded like grandpas ol' moped

[superhawk221]

Add some liquid oxigen, some talc. and watch the flame increase to a more agressive steady combination!

[Rady610]

awesome

[alewisgb]

Use a little big grain aluminium too like bb size and see what happens

[peanutlovers42]

the aluminum is too coarse



[madcyborg]

The aluminum has a higher starting point..... 15% or 10% alumine FINE grain, and 20% iron oxide.... the iron gives a better fuel supply (SELF oxidising) and will get the aluminum in the burn

[Downfacingdog]

Do you cook your fuel or is it tamped powder........either way, you seem to be running rich on most of those tests........remember, aluminium is a fuel, so maybe bump your oxidizer a bit. Great job.

[johnnyoverkill]

cut a soda can rap 4 times no more blow out ;-)

[shthapp69]

cool

[Jacper60]

try with magnesium and copper oxyde :D

[bunny153649]

when i cook it, it caught on fire!!! PLZ HELP/ADVICE!!

[rmoss15]

@bunny153649 try using a lower temperature

[danaownsall]

@bunny153649 use a lower temperature and fully dissolve the rcandy in water

[TotallyMADDtv]

@bunny153649 make sure its not on any gas burner or electrical, ceramic stove top you want something that can heat its self like an old electric wok or something like that

[Downfacingdog]

@bunny153649 Cooking is for the women folk! Real men tamp their powder.

[Armstrong202]

wheir can i get sulfur

[roboticmehdi]

i think your aluminium powder size was big, because it is seen that most of them burn outside the motor( you can see the sparks). also, did you melt ingredients together or it was just powder pressing the propellant?

[ritchiebarber]

The 65- 35 - 20 are amounts in grams correct? When adding 15 % aluminium powder i assume its 15 % of a 120 g as per you recipe so 18 g aluminium?

[rmoss15]

If you are referring to the final test, then you are correct but for the others there are some irregularities.

[kobasica]

use steel casing next time and stand next to it

[runescapeownsnubs]

All them melted cases are telling you to perhaps not use plastic ones lmfao? sped

[Zink575]

How did you create your nozzle?

[rmoss15]

I used rammed Bentonite Clay as the nozzle for these tests

[sakura123451]

@rmoss15 homemade betonite clay or store bought

[seuntjie900]

@Zink575 if you dont know the nice name for it, like rmoss15, its powdered cat litter

[DANIELBACIO]

what did u use for an ignition system?

[rmoss15]

A car battery hooked up to a momentary switch connected to a nichrome bridge wire similar to the one James Yawn describes on his website

[pyrocrazyUSA]

3rd one would make a great tail and burn very powerfully

[therealgrobmotoriker]

Have you ever tried to put a little Iron(III) oxide in it? Combined with magnesium it is a nice mix. For example 30 g KNO3, 15g Sucrose, 7g Corn Syrup, 1.5% Iron(III) oxide and 7% of magnesium powder or granulate. P.S.: The dates of the sugar mix wasn't my idea.

[antiswattt3]

powerful stuff.. and just 400 mesh.. thats great ^^

[anonarob]

ive found that aluminum tube work great+ it doesnt melt.

[randyrox69]

@anonarob ohh not to mention if you use fast r-candy it explodes and shoots shrapnel every were (Y)

[anonarob]

so. r-candy shouldnt explode.

[randyrox69]

@anonarob mate i have has soo many catos its nit funny honestly the safest is pvc

[anonarob]

@randyrox69 could give a fuck how many "catos" youve got. dont meen shit to me. i do my shit and you do yours, if im the one that ends up with shrapnel in my brain....

kudos to you.....

[randyrox69]

@anonarob dude chill the fuck out man im just trying to fuck stop ya from hurting ur sellf iv got bits of steel in my legs from a rocket and yes steel wich is alot stronger that aluminum all im saying is just stay safe iv lern the hard way

[anonarob]

@randyrox69 youve learned the hard way, now its my turn.

[randyrox69]

@anonarob haha ok man just be care full :P

[anonarob]

@randyrox69 i wont.........

[smokescreenninjato]

neat

[jamecrowley]

cool u should use a metal engine instead of plastic

[zurkFuher]

lol ed563 doesnt even have a clue to what the hell he is talkin about lmao

[MorsamMosa]

yes

[KarenYannick]

how fine was the aluminium?

[david1513]

another rocket builder was doing melt fuels / cooked fuels and had alot of exsplosions he then turned to dry fuel and never blew apart again, man he had some big exsplosions too, the biger the diamature engine the biger the hole 1/8 and 3/16 is the norm,

[david1513]

nice test, good job! but i noticed sparks thats a indication of the fuel not being mixed good enough the kno3 is still in pellet form can plug the exhost outlet and blow apart but it could also be the alumunum oxide burning, if your useing a dry powder form try a rock tumbler with ball bearings in it to crush the pellets of the kno3 finer, if your doing a melt on the fuel add water to it then boil it down keep stureing dont stop, cook it till its brown and a stickey goo, David Coffin*

[pevargas]

Good experimental work! Check out Richard Nakka's website (you might have already). Richard wrote the book on candy propellants and offers good insight to the internal workings of propellants in general. Compressed propellants work well for end-burners as long as there are no cracks which result in CATOs. Good luck.

[ed563]

Try peeing in the recipe.

Urine will up the PH oxidizer level, thus releasing the protons needed to reach supersonic thrust. (it triggers a Nero plasma sequence)

Similar to the flux capacitor results, in the movie back to the future.

[jorkey0roblox]

yes i know that works. i forgot about that but maybe ill try that to...

[TheSteveMedia]

@ed563 i rarely bust out laughing while reading youtube comments...but this was definitely one of those times

[rgmcall]

@ed563 So Urine Is A Catalyst In R Candy?

[kobasica]

@ed563 or alternatively you could take a dump.

[djd904]

@ed563 I think your only result would be deadly white phosphorus LMAO

[SmoocknJinx]

why did you only do static tests?

those could have gone to space xD

[jorkey0roblox]

lol ya

[SulaFreaks]

3nd was pefect!! alot of energi to!

[jhinro999]

2nd ones was like ripper is comming

[pyrocrazyUSA]

the 2 last ones are the best

[dragonridley]

I wonder if you went more for space shuttle and used NH4ClO4 instead of KNO3

[laboo69]

When you say "powder fuel" do you mean a rammed grain instead of melted and cast?

Interesting that the "powder fuel" consistently lit the aluminum very well. I'm not sure whether the rcandy didn't light the aluminum, or burned it all in the motor so it didn't throw sparks.

The effect of the sulfur was pretty obvious.

[rmoss15]

Yes the powdered fuel is not cast, simply rammed into the casing. Though I have had a lot of success with r-candy using aluminium and sulfur with no glucose syrup, I have a video somewhere.

[markov4k]

please write me the components that you need for a bigger scale of rocket, i mean something like for a 30 kg rocket

[meganubis]

if u get a fual thats is to powerfull add a little bit of baking soda to slow it so it lasts longer in flight

[speedomike747]

try adding C4 :P

[wattapassa]

...nothing would happen.

[speedomike747]

it would give a bang :D

[wattapassa]

no, C4 is a secondary explosive, meaning it would need a shockwave to initiate. it doesnt actually blow up. you can light it, and it actually burns a bit like camphor!

you probably saw it in films, where the guy gets out some modelling clay, and sticks in a little pen like thing. the pen like thing is the initiator, or primary explosive.

[speedomike747]

no I saw it on Brainiac :P

[wattapassa]

...what, someone adding C4 to a sugar and potassium nitrate rocket, and it would go bang? id highly doubt that. braniacs fulla bullshit anyway.

[speedomike747]

I know

[ChemXu]

The 2nd one almost looked like a strobe rocket mix.

[Mrluisao17]

dude use some iron oxide on the mix.

[utuber1418]

Red iron oxide and allumin make thermite. you cannot have a thermite rocket. lol

[Mrluisao17]

i think it would be very powerfull

[megapyro013]

you could put a bunch of thermite at the end of the rocket so it light in the air? OMG i might have t do that

[utuber1418]

yea, its bloody beautiful!!

[propyropower]

would it help to exchange the

S for red iron oxide,it might help improve burning,and maybe leaves the casing in one piece...very nice vid +5

[codydean10]

where do you get aluminum powder

[RicardoGarciaPino]

hey, why the second one coughs? happens to me all the time...

[TheAussiepyro]

the 2nd one would look nice in the sky

[ventsi]

Try adding 10% KNO3 to make up for the extra fuel value of the aluminum , don't go overboard though or it will CATO.

[jriske90]

instead of this, to get a faster more stable burn you could use red iron oxide witch is much cheaper and i personally thinks works the best, but i think the ratios in number five was the most effective

[strekstreek]

the first one looked more stable than the others

[nirvanafan833]

hmm second one is almost a strobe mixture lol. third one hurt my ears, but the fifth one looks pretty sweet, umm for improvements I think maybe add some carbon in the form of a fast-burning charcoal, that'll increase gas production, and maybe try some other catalysts, but about 2-3% added charcoal should make more gas, remembering carbin is a very light element. 5/5

[rmoss15]

Thanks, I will try adding some Charcoal into this mixture.
