HTP Kerosene Thruster

[Mr420ways]

so does it have a ship to connect to? ..no? lame

[earlyhemibill]

Shock diamonds! For those who don't know, each shock diamond represents 1 mach in exhaust velocity! The thrust must be incredible!

[tubelib]

did you say peroxide and kerosine?

[pyroman675]

wow dude thats just crazy!

[muthafuckindevilsson]

Cool!!!! it uses expensive metals and fasteners, looks really fragile, expels flammable kerosene vapors, is shiny, and probably costs tons of money!! The perfect toy for any guy!

[TheVictor6951]

looks like combustion system of a G.E. COMBUSTION TURBINE,,

[teomeimf]

Amazing how tight the flame stays. It would make a great plasma cutter for steel too.

[MrBrownstoneize]

Why does it look like the flame is in sections?

[Eagle1Division2]

@MrBrownstoneize

@UnleashTehNoob

BUahaha! Okay, I'm so sorry. Youtube must've glitched up or something! I hit "Post", and I got an error message. I refreshed the page and nothing showed up. I swear I didn't mean to do that! O.O

[dMemphys]

@MrBrownstoneize Hello! To try and answer your question, the 'sections' you're talking about are, if I'm not mistaken, the diamonds @JJCarbon is talking about. They're due to a difference between ambiant air pressure and the pressure of gases exiting the nozzle. Try and hit 'Shock Diamond' on Wikipedia. Regards.

[MrBrownstoneize]

@dMemphys Thanks for the education. Good to see that the tube isn´t all about trolling.

niiiiiiceeeeeeeee



[lovegunz1]

that happened to me once when i tried to light my fart on fire

[rocketman221projects]

How much thrust does this engine put out?

[astro1abe]

wooo my bbq scorched

[trixigt2]

You invested over 1 000 000$ into that shit and you couldn't even buy yourselves an HD CAMERA?!

[JohnxWaynexGacy]

Can anyone please explain to me why the exhaust flame looks like it has multiple points of propagation

[bitchezcrazy]

@JohnxWaynexGacy shock/Mach diamonds

[carpetmonk]

anyone reading this happen to be a designer or a technician? hell even a physicist or theorist that works in r+d for this company or any other that developes propulsion systems? my question is, can anyone explain the physics to me, of how the exhaust stream seems to refocus itself? that discolored temperature differential bubble, or different fuel composition percentage.. that "ladder" of bubbles you see in missile, rocket exhaust like this one? HELP!

[IceSynth]

@carpetmonk

Read NASA SP-125

[carpetmonk]

@IceSynth thanks for the info, it brought me to a great nasa archive site.. but nothing particular to the paper you mentioned there.. number one result was summary for the DART space vehicle, perhaps it uses the engine you mentioned, if it is an engine. great site though, im going ot have alot of fun reading from this. thanks again for the idea.. is iceSynth becaus your into chemistry? exothermal reactions? sodium acetate?

[whatisfloyd]

@carpetmonk It all depends on the exhaust pressure and the ambient pressure. Flows such as that one can either be underexpanded, overexpanded, or perfectly expanded. Overexpanded nozzle flow creates oblique shock waves at the exit. When the shockwaves interact further out from the nozzle exit it can create complex patterns of shockwaves, which makes it look like the "ladder" of bubbles you referred to.

[OnnomonnomonnO]

wtf is wrong with a sound

[RoudyRaccoon]

But will it blend?

[negerN1337]

omg it's shooting lazers

[gijsoerlemans1992]

woooow . now you can light you smoke REALLY fast

[plbyrne]

How much thrust ?

[mynamearekid]

Why is everyone so worried about diamonds??? You obviously have to measure thrust with more than sight and cool shapes made in the flames. Diamonds are absolutely useless to discuss.

[slipknotmaggot777]

198,666th view... yess

[hammeredinfire]

Oops, sorry. I was watching this vid again and accidentally hit the thumbs down button when I was trying to hit the mute...

[jeetendrag10acc2]

anywhere we can read some good intro to the physics of rockets you guys could recommend?

[jag9998]

Quick question: What is the significance of the angle of the convergent section of the nozzle? Is it for reasons of smooth gas flow or just heat management? Nothing I've read discusses it.

[hammeredinfire]

@jag9998 yes, both. it isn’t covered much because it’s not very critical, you can just about design it by eye. you make it smooth as possible for stable flow, but no so long that it impacts cooling (or weight and size). besides, delta v is less than M=1 in the convergent section, but many times that in the divergent section, so the convergent part is fairly short. btw, i always thought HTP and RP1 produced a nearly invisible exhaust, i wonder if this one is running rich to keep the temp down.

[93394348]

well the sound effects were fake enough

[swriel]

a mah firin mah lazaah

[ruckingfetards]

congradulations, yu invinted a blow torch. dumbasses

[holmesteadready]

@ruckingfetards learn to spell before bagging, retard

[ruckingfetards]

@holmesteadready

im sorry i cant spell like a professional faggot like you

[holmesteadready]

@ruckingfetards hahahaahahahhhhaha you're so witty..

[FROSTYDEAN15]

wow

could an engine like this lift a person if you had more of them?

[Dragonno96]

@FROSTYDEAN15 yes. I don't know how many would be required to lift a person of average weight but you'd need allot of them

[xBounty9]

holy shit its a lightsaber

[Lowracerman]

I like this. I have my own machine shop I would love to have some plans so I can build one. How much thrust does it produce? This looks like it is more in the order of a rocket engine. It has been about 20 years since I have built any liquid fuel rocket engines. I have been having a lot of fun building pulse jet engines.

[chaosopher23]

@Lowracerman Get Rocket Propulsion Elements and a few other tech manuals, and don't bother with plans. Make your own plans. You have a machine shop, make a rocket. Show it on YT, of course.

[TwigletWoof]

anyway, linuxknobification:

why on earth would I fake my age?????? That is the sort of thing a stupid idiot like yourself would do.

[TwigletWoof]

linuxpowerification has posted a comment on your profile:

little boy??? your fucking faggot piece of shit,grow up and remove your faked age from your profile.

You can reply to this comment by visiting your comments page.

Obviously your balls haven't dropped yet. or you would have had the balls to have post your Inane and most vacuous comment here instead of direct to my profile you looser. Looks like you have plenty of heat from others on here too. the common factor here is you! numb nuts.

[fabianmartin88]

Nice grill man:)

[girrrrrrr2]

Personally i like the look of the diamonds.

[leventhefox]

dude that not a thruser that a weapon that burn throw bone

[hellzheroman]

well done you worked out how to make a little flame



[linuxpowerification]

why are you shacking the camera??? -.-

[TheHappyShack]

@linuxpowerification your an idiot

[122later122]

nice flame ^^

[ACiDxVoLTaGe]

Wow it's a blow-torch with added sound effects!!!

[deepfreezee232004]

thats one hell of a cigar lighter can you make me a zippo that will do this

[rndstuff123]

wow looks bad ass!

[and1832]

How much thrust does this have and also where can I find how to make one? Thank you.

[pietzeekoe]

: o pretty.............

[Alembic25]

British style rockets! Good to see you're keeping up the tradition.

[thecannonball34]

so... it's like a miniature afterburner?

[Preludxtc]

thats badass

[jep0rox]

shi*t thats cool

[J0Boa]

I like the shock diamonds

[MrThunderstarUK]

There's no flame to begin with because the engine is started using HTP fed through a silver catalyst, so what you are actually getting is high temperature steam, then the kerosene feed is turned on and that's when you see the flame. The engine runs for a few seconds like this and then we turn off the kerosene which takes the unit back to being a "steam engine". We only did a couple of tests with this engine before modifying it to use a solid fuel instead of the liquid kerosene. Starchaser

[TheBattleWagon]

SEE! now that's what

I'm talking about!

[dimephixxer]

oye que es eso? responde en mi perfil !!

[iamtherobotofpop]

OK seriously..... is it fake? or not???? did you even check out the site listed in the info??? this is COMPLETELY LEGIT!!!!! just check out the site, these guys know what they are doing..... now get over it......

[TwigletWoof]

@iamtherobotofpop

Thank you. Some idiots just go off on one and all because they have a little knowledge, which, in the wrong hands, can be dangerous. Case in point.

[MrsCrapola]

agree with pollo

[TheEdenKnight]

thats fake -.-

[TwigletWoof]

How can it be fake you idiot?

[TheEdenKnight]

@TwigletWoof just look closely you fargot

the fire itself is just one taken picture and is shacked by the video program the box where it shoots out is purely black so you can add real smoke effekt ..

the fire has an absolute wrong color btw

[TwigletWoof]

So what if the box that is taking the brunt of the flame is black. I am sure that if you were heated up by a flame like that you would smoke far more but smell a whole lot worse. Nothing here is superimposed or 'shacked', I am sure you are just another one of these Conspiracy theorists aren't you?

By the way, what is a 'fargot'? You can't even type properly, probably because you are too busy playing with your dick. what a wanker you are.

[TheEdenKnight]

@TwigletWoof say what u want and im not one of those 'Conspiracy theorists' im a realist and i know how to fake videos and this one is definitively made on PC lust look at the camera fool

[TwigletWoof]

1. you can't see the camera - You are the fool.

2. Look at the motor itself @ around 24 seconds you see the smoke coming off it because it is getting hot.

3. from that point you can see the first shock dimond.

4. the only POSSIBLE fake part of the whole vid is the sound.

Now grow up and stop being a knob

[TheEdenKnight]

@TwigletWoof oh cmon go home suck cocks .. i dont need ur aproval its fake there u have it

[TwigletWoof]

Why did you remove that last post. Affraid of sounding a bigger cock sucker than you actually are?

Who cares if the camerawork is a bit shakey, it is obviously being held in the hands and not on a tripod.

I certainly wasn't giving you my approval or otherwise, you wouldn't understand it probably.

I was stating my opinion, which was contrary to yours and you didn't like it or just couldn't handle someone having a differing opinion. Now go home and cry to your mummy you big wet ponce.

[TheEdenKnight]

@TwigletWoof i didn't want to del it .. i just did the number 3 2 times and had copied it to my textboard i deletet it and i have typed ctrl + c again .. so my clipboard was empty and the text was been lost ..

[linuxpowerification]

@TwigletWoof

im the idiot??? he is the one who is shacking the cam.Looks like you are the idiot and dont see that.

[GeekMaster6000]

@linuxpowerification Yeah....... You're an idiot. :P

[linuxpowerification]

@GeekMaster6000

kiss my ass troll

[GeekMaster6000]

@linuxpowerification Soooo, you being a complete moron makes me a troll. Makes PLENTY of sense.

[Hateocracy]

@TwigletWoof $50 says the person calling it fake believes in God.

[barbodo89]

@Hateocracy +10

[david52875]

@Hateocracy Wow. your comment was stupid AND it was a reply to a post one year ago. Way to go.

[someguy018]

@david52875 Hah, yeah.

[Hateocracy]

@david52875 What does the post being a year old have to do with anything?

And relax, it was a joke dude.

[jmar1371]

@TheEdenKnight You sir, are an idiot. Is everything that you don't understand "faked?"

[TheEdenKnight]

@jmar1371 omfg what is your problem ? is everything that looks real ? do you know how to fake vids ? did u ever do something like that ?

if not then shut up not everything that seems real is real -.-

[TheEdenKnight]

@TheEdenKnight wah fuck "is everything that looks real ?" -> "not everything that looks real for u is real"

[jmar1371]

@TheEdenKnight Dewd... Knock off the drugs...

[jmar1371]

@TheEdenKnight I don't make fake vids... Instead, I make REAL rocket motors. What you are seeing in the video here is quite real, Zippy. The only thing faked here was your education. You should slap your parents.

[zythepsarian]

lovely little engine

[TheCherokeeboy]

wow cool. what the hell was that thing

[Marvin0Martian]

Mach diamonds indicate the velocity of the plasma exiting the nozzle. Each diamond represents the speed of sound. 8 diamonds would be approximately 5600 miles per hour for the gas seen escaping.

[cornershot94]

holy cr****************************­*******p

[mastermakerhacker]

@Marvin0Martian

so the speed of sound is about 700 mph then? so if i count the amount of mach diamonds and then multiply them by 700 i would have the speed the gas is escaping?

[pollolocol]

The number of shock diamonds is a function of the exit Mach number, atmospheric pressure, exit area, and viscous dissipation. It wouldn't be possible to calculate the speed of the flow by counting the shock diamonds without some pretty complex analysis.

[bobdagangster]

shock diamonds can appear in any supersonic exhaust. they do not represent the speed of the exhaust (and the exhaust is certainly not plasma).

The presence of shock diamond means that the nozzle shape is not perfectly optimized for the ambient atmospheric pressure.

[Marvin0Martian]

I stand corrected on the diamonds however the hot gas exiting the engine is definitely a plasma. That's why it is emitting light! Any gas which has become ionized to the point that it emits photons (even infrared) is a plasma. Not unlike a flickering candle flame - plasma.

[bobdagangster]

you are correct about plasma, however, the gases are not ionized, only very hot. They would need to be a lot hotter to be ionized

[Dierwolf2000]

otherwise you'd see an even exhalation of flame, like a lighter only much bigger?

[JJCarbon]

@Marvin0Martian Diamonds alone don't equate to exit velocity (they do indicate supersonic flow). If gas has fixed velocity diamonds will still vary on conditions, principally pressure differences between ambient and exhaust. An engine designed for max thrust will ideally exhibit no diamonds at design pressure (max effective exhaust); the cessation of diamonds in non-optimized thrust is due to turbulence and viscous damping in the wave mediums; an ideal system would yield infinite diamonds.

[IanRobot]

@JJCarbon I love how all the people on youtube are not dumb teens that don't use proper grammar and that have no clue of what the're watching.

[Eagle1Division2]

@IanRobot

I'm a teen and I don't use improper grammar all the time and I really know what I'm watching.

It's a homebuilt rocket using hydrogen peroxide oxidizer and kerosene fuel. LOX would be a better oxidizer but is more difficult to work with due to it's cryogenic nature and even larger oxidizing effect than peroxide.

The most efficient rockets use LOX/LH-2, but liquid hydrogen isn't dense, so it's difficult to get a large mass ratio, not to mention it's even far colder than LOX.

[UnleashTehNoob]

@Eagle1Division2 Jesus Christ. How many times did you hit the post button? 11-tuple post...

[snyp3r6]

@IanRobot Would that also include punctuation?

If so, you may want to correct your sentence, or be a "dumb teen that doesn't use proper grammar"

[LlNUXPYTHON]

@JJCarbon wtf do u mean diamonds dont make from fyr

[whatisfloyd]

@JJCarbon I'm not sure if I agree with the part where you say infinite diamonds would be ideal. Diamonds indicate that the nozzle produces overexpanded exit conditions which, from my limited knowledge, would be less safe than perfectly expanded or underexpanded exhaust conditions. This, I believe, would be because the shock waves are closer to the occurring inside the nozzle. Perfectly expanded exit flow from a nozzle is ideal. Give me a reason why I'm wrong if you believe I am mistaken.

[whatisfloyd]

@JJCarbon Maybe I misunderstood the last part of your comment. What I said seems to be what the middle section of your comment stated. oops

[METZOMB09]

@JJCarbon Dude, I seriously learned 1000 times more from you writing that paragraph than I ever would from my entire high school years ._. thanks :3

[Tyrannobeast]

Mach (or Shock) Diamonds are formations of stationary wave patterns that appear in the exhaust plume of a rocket engine. They look like ovals of a lighter or darker color than the rest of the flame.

[robfromorlando]

Beautiful Mach diamonds: a sign of precise engineering.

[reimers84]

Why would mach diamonds be a sign of precise engineering? Are you saying that a rocket motor that produces mach diamonds in the exhaust jet is a better made engine then one which does not? Don't understand why? What do the diamonds signify? Not trying to knock your comment man, I think they look cool as hell but other then that Im just trying to figure how they make a better rocket.

[himoroyden]

right. respect to the engineers. I would truely like to support that kind of projects... Very high quality work. Is there a sectional and/or a principle to get involved to?

[Blondets1]

at 20 seconds i counted 7-8 mach diamonds! That is one powerful little rocket

[johnnytheprick]

BLONDEST1,

wth (what the hell) r "mark diamonds"?

[TheFluorineMartyr]

Am I right in thinking that liquified N2O4 is, overall, a superior oxidiser to H2O2? If so is toxicity the only factor contributing to the latter prevalence in rocketry?

[poptartpencil]

where can you buy them or find plans

[heffeque]

Interlacing was pretty distracting :-/

[brreed93]

i need one for a rocket or something

[Msagro5]

Yeah Napoleon.... Maybe you could take it over some really cool jumps....

[brreed93]

lol

[Msagro5]

Brreed93, Glad you weren't offended by my comment. It's just that when I read yor initial comment, it sounded JUST LIKE a line out that ever-so-famous movie. All the best to you....

[nicksynnz]

Great vid, I love those mach diamonds

[pow0006]

its like a perfect model replica of the nasa test!

[SoraKurosu0]

I agree with CJ

[heroineworshipper]

so much thrust, the camera shakes!

[eleszar1]

;O i bet in 10 years from now we could use layzer guns :P

[Joeli086]

From what I remember Laser weapons are banned by the Geneva convention. Not allowed to use them unfortunately.

[Shatteredworld]

I don't think anyone really cares about the lasers being used as weapon, even if it is banned by the Geneva convention (i tried searching for it...but it's too troublesome). If they did we wouldn't be developing the Boeing Yal-1, literally a flying laser

[Joeli086]

I remember seeing something about that recently.

I also tried a quick search for the ban with no avail. The reasoning was if you have a laser you could essentially cut a persons limbs off while at the same time cauterising the wound so they wouldn't bleed out. If they weren't rescued then they would die of dehydration over a longer period (if the shock didn't get them first) for a horrible death.

I think you're right anyhow, looks like no ban and we have nice scary flying lasers of death.

[Shatteredworld]

Yeah, i do know that many human rights activists are attempting to classify it as breach of human rights, with what you just mentioned, saying it's Inhumane.

[piranha031091]

If you talk about the Air Borne Laser project, it is not considered as a weapon, as it is supposed to destroy missiles, so it is only defensive, not offensive.

[Shatteredworld]

However, because it's laser and calibrating can be done on the fly. it CAN be used as weapon. and Defensive tools can be used as a weapon. however since this conversation is based off a comment that isn't related to the video...so...

[AnselmoFanZero]

So what? They already use lasers for destroying landmines and taking down missiles and mortarrounds. But: To kill one or more people its still easier to bomb or shoot em...so it would make ANY sense to use a railgun or a laser or whatever.

[aval1998]

skywlaker says:im ur thruster

[firdome]

I'd like to mount the rocket in the back of my van...not to go fast, just to "toast" tailgaters!!!

[AZNPKER123]

Hah! i need that for my truck

[UndertakerWoW]

lol i wan to buy a plan how it works <3

a link was nice ²

thank ya

[hornitpilot]

WOW what da hell is that for you gonna mount it on a rc jet

[uetzel]

cooooool

[08CJ09]

what is a mach dimaond? can someone explain to me

[rocketlad22]

a mach diamond happens when the flame goes faster than the speed of sound. in the vid you can see 4 of them spaced out in the flame

[08CJ09]

wow, interesting

[goldencricket]

are those tiny mach diamonds!!

:)
