@Fartingmonkies well, I dont know much about them, but I guess. Although I think a forge uses more of the captured oven-like heat then just a direct flame.
@hotpc76 the compressor is actually a pre-built electric centrifugal blower. You can oder them online. Just realize this is not a complete gas turbine engine
@samus989 It does look like a afterburner, but its design is more of that of a can-type combustion chamber. Im just pushing way to much fuel into it, but thats cus I wanted to see how it would take it. And yes it is not an actual full engine, but a radial electric blower with a crude home made can-type combustion chamber.
@JetAce08 Afterburner is exactly what you did with this, after the power turbine, you blow tons of high pressure fuel into the air flow, giving you lotsa oompf for short periods of time. A combustion chamber on a jet uses venturi action to take high pressure low volume air, and convert it into high volume low pressure air so that power can be drived from it and it doesnt get shot out the front(compressor stall). Is the air from the blower compressed at all or shot out like a hair dryer
@samus989 You are correct on your description of the two, which is why if you knew how this design was built you would change your accusation. An afterburner is placed aft of an actual turbine engine. It is also comprised of fuel spray bars, an ignitor, flame holders and jet pipe. This design uses a two stage centrifugal compressor (much like those on early turbines) a diffuser, a fuel injector and combustor liner (or flame tube). Just like a combustion chamber it has a primary combustion zone
@samus989 and dilution zone, these of which a afterburner DOES NOT have. This design also uses much lower fuel then an afterburner of its same size would use. The answer to your last question is yes, the air discharge is at a much higher pressure and velocity then a "hair dryer".
I made a gas turbine, took months to get the flame anchored in the chamber, thats the hardest part of the design. Looks like you cracked it. My vids uploaded.
@wheelnutt Yep, dont be fooled, it also to me several designs to get it right. The biggest key is to understand only 20-30% of the total air is used in combustion, and ya got to have that little pocket of low velocity air to keep the flame anchored.
Oh excellent! I've been wanting to make a backyard jet for a while now, but I keep getting hung up on the combustion chamber design. This is a perfect way to test how it would work! Thanks!
Nice work! just fyi if youre interested keep in mind that complete combustion of the fuel requires there to be the perfectly stoichiometric ratio of fuel/air. Not important unless youre gonna build a full sized engine though. Have you considered going into aerospace engineering? Thats what ive been doing for almost 4 years now.
@whatisfloyd I have dreamed of goin into the aerospace field literally as long as i can remember, I ended up goin into the corps hoping to get power plants but ended up getting cryogenics. My plan now is to stick with cryo and aiming to get a cryo job at Edward's AFB if they have one
Looks like all you have there is the blowing side of a vacuum cleaner blowing through a tin can while you pipe in some propane gas to burn. Not anywhere close to a "jet" anything. Maybe you can use that thing to heat your garage in the winter.
@royalbrainwave well yea, that is what it is. However if you knew anything about jet engines you would see how similar it is to what I said it was. Perhaps you could also read more then just the first word in the title and continue to the "combustion chamber project" part...and like I said, not be ignorant.
@JetAce08 Actually, that seems quite similar to a ram or scram jet. They don't use blades to compress air fuel mixture, instead, the incoming air does it. If you could choke down the out put exactly the right amount, it might actually make a half decent model ram jet , except that the incoming air is from a vacuum cleaner or something, instead of the whole engine flying through the air.
I dont know if your still working on these turbine engines but you may have better luck with using stainless steel vs that food can , you can get ss tubes from a lot of kitchen items , and bathroomitems
Germans figured out very very soon in WW2 why any material for example tin cans are not a good material to use in jet engine. Okay, nowadays many military jet engines takes x+x hours to service after flying x hour. But 60+ ears ago lifetime of an engine was counted in hours, due to lack of heat-resistant materials.
@jolde3000 very true, heat resistant materials and lack of hot end cooling designs. Now there are advanced methods of turbine nozzle and blade cooling techniques, as well as lowering the combustor exhaust gas temps.
Well, if it's possible for you sure! That would be very nice indeed!! :D
I'm looking forward to make a little "toy" like this, but i'm a bit afraid to play around with propane, can you pinpoint me to some safety issues? Can it rev back to the tank?
By looking at this i can see how simple a jet engine can be (of course you're just shoin' the combustion chamber) like everyone said here... add a turbo-charger compressor shaft and i think you'll make something really neat!
Impressive video! It answered me a lot of questions! :)
this was amazing to me until i realized that the air blower was still on, which made me sad:( if you could get one to work that way without the air blower I'd love to see it, because right there, all you're really doing it blowing hot air.. probably almost no thrust at all provided by the flame. i want to see one that actually works itself... this is like blowing on a candle but not quite enough to let it go out:(
@DiamondPilotDan Well, for one you are correct, there is very little thrust created by a combustor, thrust is mostly created in the compressor. I hate to tell ya but to get this style flame is impossible to do with out a compressed air flow. With out the blower or a form of compressor, you would just get something that looked like a very large candle flame or gas grill flame with more yellow color then blue. A torch could give you a blue flame but it would be small and not look like this.
@TheBigDogHouse Nope, im using propane, the blue flame comes from the higher air pressure and better combustion characteristics. Blue flame is hotter then yellow flame, a gas grill has blue and yellow flame due to its lower air to fuel ratio and less efficient combustion process, where as this has only blue flame inside the combustor.
Hey JetAce08, dose that have an auto cycle or is it a combination electric motor plug'ed into 240V outlet? I would like to see the entire application. That technology is in use today but the way you fabricated it has great potential. I was like I don't hear the ignition sequence, you know the sound of the ticking igniters. Either way it goes thats still pretty cool please share more.
@MrAmirk thank ya, im working on a new chamber that uses the primary zone off a J79 liner and a 3 stage electric blower as a air source, I also have a JT8D liner ill use later, but i want to keep it in good condition cus it is perfect for showing the different combustion zones.
@zero00tolerance This is a combustion chamber and does not actually produce thrust, its the compressor in a jet engine that produces the majority of the thrust. Due to the low pressure electric compressor, and it just being a combustion chamber, it produces no thrust. Connect this to a turbocharger from a car, add some other parts, and then you would have an actual jet engine and thrust
@42Musica thanks man, im working on making a a better one from scratch that i can reproduce, as well as one using a J79 liner. i may try to sell the ones i build from scratch, many ppl have asked me how to build them.
@JetAce08 And also, I would love to build a simple pulsejet or turbojet but my parents won't let me because they think it's too dangerous, it's so annoying!!!
@coolguyvideomaster I dont really have the parts anymore to show how I made this particular one, however I will go to home depot and see if I can make an even better one when I have some extra money.
@BradenMaggs Well its not exactly and engine, its just a home made combustion chamber, since then i have acquired an actual jet engine combustor liner and I am in the process of designing a new chamber using the that liner. I have kinda gotten away from building it due to lack of funds recently, but I will soon be finishing the build, along with a video of combustion chamber principles.
I can tell some of these folks are real dumbasses. And have never owned or used a blow torch. Im old enough to have done so and they do produce thrust. if they had a throated chamber exhaust there would be more thrust. Light one up and turn up the fuel, or take an acetyelene torch and turn it up strong, there is a thrust. But in either case, will be enhanced with a thrust chamber exhaust. Why make a dumb statement that exposes your ignorance to the world if you have never done any of this??
Yes, this is a great work for a home made small scale afterburner! On this video we can see a mach ring or shockwave, but if you can increase the nozzle presure ratio, or if you can build a controllable exhaust diameter nozzle, it will be a real afterburner in thrust and in effect.
@po620100 This is an old one I made. Due to the low pressure compressor, and it just being a combustion chamber, it has no "power". Connect this to a turbocharger from a car, add some other parts, and then you would have an actual jet engine and thrust
@reverserbank The fuel system was propane, used a grill sized propane tank, grill needle valve adaptor, copper lines, and some brass plumbing parts with holes drilled into a cap to inject the gas into the chamber.
@JetAce08 Thank you for your answer ,it's really helpful. A little more question How did you control the relation of air-flow with gas-flow { C3H8 + 5O2 --> 3CO2 + 4H2O ... } if you did, can it's actually go wrong ,I mean explode ... I'm really interest in aircraft engine :P especially Turbofan Engine. Did you study about these ? I'm about to study Aerospace Engineering in college
@thegarlands04 well...not really, the purpose of a combustion chamber is to heat and so expand massive amounts of air through combustion of a type of fuel. So you would have a low volume problem, and no room for dilution air, so I would say not without some serious changes. The area in a combustor is about 40% combustion zone and 60% dilution/cooling zone, where as in a torch, 100% of the area is used for combustion. In this video I was pumping way more fuel then needed, for looks.
@thegarlands04 yes, also as the extra (dilution) air is added to the flames, the energy is transfered to that air, expanding the dilution air, and cooling the gasses from the flames. That way the air going into the turbine is cooler then the primary combustion zone air. If you just used a blowtorch, the gasses going into the turbine would be too hot.
@JetAce08 ah so a blow torch would make too mutch heat and all you would have is a fance little heater with heat coming out of both the intake and exaust end and a few disfunctional fans fo decoration. what i do want to know is how i would inject fuel into the combustion chamber without flames leaping up the fuel line and into the tank.
@JetAce08 so it would heat up both ends and transform the jet engine into a cool looking heater. well then how would i be able to injct fuel into the cumbustion chamber and light it without flames jumping up the fuel line and into the gas tank and barbequing me
@thegarlands04 lol, if your using propane, that is a common misconception, three things are needed for fire, spark, fuel, and oxygen. In a propane fuel line, there is ONLY propane, no oxygen, there for, the flame will not go into the propane line. Ive held one of my propane fuel systems with a flame right at the end of the injector, and the flame just sits there. If you put too much fuel pressure, the flame will blow itself out, and too little, and the flame will just disappear like a lighter.
Nice job, but the is from Aluminium which melts at only 660 Degrees Celsius. Most Jets go up to 800-1200 Degrees. I would take a exhaust pipe from car at scrapyard. It can take enough heat and is bigger and thicker
@kaas94 if your speaking of what i made it from, then yes, it is aluminium, but due to its construction it does not heat up to that high of a temperature.
Real nice work, man! I couldent do better if I tried! But you need to take 05u16hep's advise and then, who knows? Mabey you can attach it to a car and use it for a booster. Haha.
so cheap... Doesnt produce any thrust... and looks like a blowtorch in an old tin container... spend some more time trying to make it a real jet engine instead of trying 2 get views on youtube as fast as u can... dumb fuckass
@ctechreviews see, its ppl like you (hate their lives and the only thing to do to get their jollies off is to make ignorant comments, most likely out of jealousy) that make me laugh. Im not even goin to get into why your a dumbass, just know I know you are. All I need to know is that people that actually DO know what they are looking at, are impressed with it, so go fuck yourself.
@ctechreviews Hah, Read the description dumbfuck. He spent a couple of days making this out of food cans and plumbing parts. I bet you couldent do any better, troll.
05u16hep is right--motorjets are hard to make in such as way as to be efficient with regard to thrust. On the other hand, you can stumble on the right configuration of parts & sizes quite accidentally by experimenting. It took me 10 years to find the best combination intuitively: if you connect a capped quart paint can (combustion section) to a capped gallon paint can (compressor) and use 1.5" openings on all 4 capped surface (& no flamesholder), you get LOTS of thrust added at the afterburner.
@cilvalization really?? first of all, this guy asked me a question so i answered, secondly, the "visual" combustor design's purpose is to see inside the combustor as it burns, not to "re-invent" it jackass.
@cilvalization well I can see your just a ignorant dumb fuck so im going to move on and actually use my time talking to intelligent people who know what the fuck they are talking about, and appreciate my work. Enjoy the remainder of your life, hopefully you....well fuck it, its pointless. Peace.
Hmm thats an ingenious way of testing a combustion chamber. I would have never thought of using a leaf blower. The main thing with this is you can actually see the combustion process and determine how stable and how well a design is working as opposed to using transducers to listen to various designs. Excellent work!
@ki4hou thank you I am currently working on a "visual Combustor" using a high power axial fan blower and a actual combustor liner out of a JT8D turbofan. It will have viewing windows in the combustor outer casing in which to look through the connector joints in the liner to see inside the liner and watch the flame process. I have a vid up describing it.
@circusboy90210 well, the combustion chamber in a jet engine purpose is to heat the dilution (extra air unused in the combustion process) and expand it, bringing the super high temp, low volume air flow to medium temp, high volume of air flow used in the turbine. By using computational flow analyses one could maximize the efficiency of the combustion and expansion process in the combustor and improve things like fuel efficiency, emissions production and maintain a smooth, fast flowing air
@circusboy90210 (cont.) stream through the combustor, maximizing overall thrust. Im sure GE used it in the development of their "TAPS" combustor, which is the newest, most efficient design of full annular combustor to date. It could and most likely was used in atomizing fuel nozzle design. Basically computational flow analyses could be used in the whole turbine engine design, not just the combustor as I have made.
I'll have to agree wholehertedly with 05u16hep... my advice to you is to first of all get your A&P license. get next to em work on em get familiar with em and then you can work your way back to design and engineering. I'm an AMT and to clear up any confusion, the diffuser takes fast moving compressed air strightens it out, slows down pressurized air before combustion, it is the nozzle thru which hot expanded F/A mixture is forced through is where the thrust is generated.
The tin can engines look like they would be a good fit for America's commuter and regional airlines. Pardon me...I meant upgrade! Just kidding--nice work!
@mikester105 thanks, its gettin hard to keep designing and building now that im in the marine corps. A barracks room is not much good for building that kind of stuff. Im aiming to be a fuel technician for nasa when i get out since my job is cryogenics now. Im goin to continue building as much as i can for the next 4 years, which wont be much, but when I get out Im goin to build a turbocharger jet engine, as ive wanted to since middle school.
In the early days, a European mob built an aircraft that used a piston engine to drive a turbofan then a fuel-oil was injected and ignited, this produced thrust, enough to get the craft airborn, your concept works, if you were to restrict the exhaust and then use propane as a starter fuel then inject kerosene you may get an interesting result, However if you do this, PLEASE BE CAREFUL,
that wont produce any thrust... when does a blowtorch become a jet engine?
u need slow, compressed air to get a good burn, plus you need to give it a smaller amount of space to burn in to actually produce thrust: jet engines are very difficult to make
@05u16hep i didnt say it was a 'jet engine'. i said it was a jet engine"combustion chamber" which is exactly what it was designed from. and yes you are right, it doesn't produce much thrust, then again, combustion chambers dont. The compressor is what produces most of a jets thrust. Also 'slow' air is what you dont want, the slower it is, the less expansion comes from the burn.
here's what i did I took a soup can like u have here, drilled a 3/8in hole and reamed it so that i could fit a 1/4in barbed hose fitting in. (it'll thread it self in.) i connected a hose to the fitting, that hose went to a 3 way compression fitting were the compressed air came in also on top of the tee fitting there was a psi guage that i could unscrew and put a funnle in to fill with gas. so yeh i did that barly turned on the air lit it with a torch..flames....turned on the air more & trust!!!
@samuelm77 , thats not a jet engine, not even close, its just a pathetic attempt to make a torch...
And the combustion chamber above is not an actual combustion chamber for a jet engine. I dont know what kind of fuel your using but its probably not the right kind, flames should NEVER come out of the combustion chamber....
ok do you have any tips. because im using orange peels in the combustian tank and wd-40 to ignite it with an air pump. i need a compressor fan but i dnt have one
Orange peals in the combustion chamber????? WD-40 and an air pump ignition????? HUH????? Your not even close to making a jet engine.... For you i would suggest making a beer can jet, just google "beer can jet instructables" and click on the first link.
The only way for the average person to make a real jet engine is to use a turbocharger. If your really interested then search "DIY Gas Turbine" although for someone your age it would be extremely difficult just to understand the concept....

MrAmirk 4 months ago 3
@MrAmirk thank ya, im working on a new chamber that uses the primary zone off a J79 liner and a 3 stage electric blower as a air source, I also have a JT8D liner ill use later, but i want to keep it in good condition cus it is perfect for showing the different combustion zones.

Hello any thrust ? for this may i ask
zero00tolerance 5 months ago
@zero00tolerance This is a combustion chamber and does not actually produce thrust, its the compressor in a jet engine that produces the majority of the thrust. Due to the low pressure electric compressor, and it just being a combustion chamber, it produces no thrust. Connect this to a turbocharger from a car, add some other parts, and then you would have an actual jet engine and thrust

I found this video very enlightening, so thankyou. Would you mind making a video going over all the aspects of this engine?
BradenMaggs 6 months ago
@BradenMaggs Well its not exactly and engine, its just a home made combustion chamber, since then i have acquired an actual jet engine combustor liner and I am in the process of designing a new chamber using the that liner. I have kinda gotten away from building it due to lack of funds recently, but I will soon be finishing the build, along with a video of combustion chamber principles.
JetAce08 6 months ago
I can tell some of these folks are real dumbasses. And have never owned or used a blow torch. Im old enough to have done so and they do produce thrust. if they had a throated chamber exhaust there would be more thrust. Light one up and turn up the fuel, or take an acetyelene torch and turn it up strong, there is a thrust. But in either case, will be enhanced with a thrust chamber exhaust. Why make a dumb statement that exposes your ignorance to the world if you have never done any of this??

@xtamared thanks, im goin to make another using a 3 stage electric compressor and an actual combustor liner.
JetAce08 8 months ago
Yes, this is a great work for a home made small scale afterburner! On this video we can see a mach ring or shockwave, but if you can increase the nozzle presure ratio, or if you can build a controllable exhaust diameter nozzle, it will be a real afterburner in thrust and in effect.

@kolbola actually this one is more of a can-type combustor design. It is a different concept than an afterburner. But thanks : )

po620100 10 months ago
@po620100 This is an old one I made. Due to the low pressure compressor, and it just being a combustion chamber, it has no "power". Connect this to a turbocharger from a car, add some other parts, and then you would have an actual jet engine and thrust

I've got some qustion to ask...
what kind of pump did you use ?
how to spray fuel in to the chamber ?
What type of fuel did you use?
reverserbank 11 months ago
@reverserbank The fuel system was propane, used a grill sized propane tank, grill needle valve adaptor, copper lines, and some brass plumbing parts with holes drilled into a cap to inject the gas into the chamber.
JetAce08 11 months ago
@JetAce08 Thank you for your answer ,it's really helpful. A little more question How did you control the relation of air-flow with gas-flow { C3H8 + 5O2 --> 3CO2 + 4H2O ... } if you did, can it's actually go wrong ,I mean explode ... I'm really interest in aircraft engine :P especially Turbofan Engine. Did you study about these ? I'm about to study Aerospace Engineering in college
Hope we would talk and share more ...

i have a question. could a combustion chamber be made using a blowtorch alone?
thegarlands04 11 months ago
@thegarlands04 well...not really, the purpose of a combustion chamber is to heat and so expand massive amounts of air through combustion of a type of fuel. So you would have a low volume problem, and no room for dilution air, so I would say not without some serious changes. The area in a combustor is about 40% combustion zone and 60% dilution/cooling zone, where as in a torch, 100% of the area is used for combustion. In this video I was pumping way more fuel then needed, for looks.
JetAce08 11 months ago
@JetAce08 and again, this is just a thrown together back yard project with basic tools, and designed for more fire then needed.
JetAce08 11 months ago
@JetAce08 so the heated air would have no ware to expand and my engine would not be self substaining. so i would have to make it bigger
thegarlands04 11 months ago
@thegarlands04 yes, also as the extra (dilution) air is added to the flames, the energy is transfered to that air, expanding the dilution air, and cooling the gasses from the flames. That way the air going into the turbine is cooler then the primary combustion zone air. If you just used a blowtorch, the gasses going into the turbine would be too hot.
JetAce08 11 months ago
@JetAce08 ah so a blow torch would make too mutch heat and all you would have is a fance little heater with heat coming out of both the intake and exaust end and a few disfunctional fans fo decoration. what i do want to know is how i would inject fuel into the combustion chamber without flames leaping up the fuel line and into the tank.
thegarlands04 11 months ago
@JetAce08 so it would heat up both ends and transform the jet engine into a cool looking heater. well then how would i be able to injct fuel into the cumbustion chamber and light it without flames jumping up the fuel line and into the gas tank and barbequing me
thegarlands04 11 months ago
@thegarlands04 lol, if your using propane, that is a common misconception, three things are needed for fire, spark, fuel, and oxygen. In a propane fuel line, there is ONLY propane, no oxygen, there for, the flame will not go into the propane line. Ive held one of my propane fuel systems with a flame right at the end of the injector, and the flame just sits there. If you put too much fuel pressure, the flame will blow itself out, and too little, and the flame will just disappear like a lighter.
JetAce08 11 months ago
@JetAce08 Come to think of it, a lighter works in the exact same way.
JetAce08 11 months ago
Nice job, but the is from Aluminium which melts at only 660 Degrees Celsius. Most Jets go up to 800-1200 Degrees. I would take a exhaust pipe from car at scrapyard. It can take enough heat and is bigger and thicker
kaas94 1 year ago

Th4Pwnz0r 1 year ago
05u16hep is right--motorjets are hard to make in such as way as to be efficient with regard to thrust. On the other hand, you can stumble on the right configuration of parts & sizes quite accidentally by experimenting. It took me 10 years to find the best combination intuitively: if you connect a capped quart paint can (combustion section) to a capped gallon paint can (compressor) and use 1.5" openings on all 4 capped surface (& no flamesholder), you get LOTS of thrust added at the afterburner.

JetAce08 1 year ago 3
Hmm thats an ingenious way of testing a combustion chamber. I would have never thought of using a leaf blower. The main thing with this is you can actually see the combustion process and determine how stable and how well a design is working as opposed to using transducers to listen to various designs. Excellent work!
ki4hou 1 year ago
@ki4hou thank you I am currently working on a "visual Combustor" using a high power axial fan blower and a actual combustor liner out of a JT8D turbofan. It will have viewing windows in the combustor outer casing in which to look through the connector joints in the liner to see inside the liner and watch the flame process. I have a vid up describing it.
JetAce08 1 year ago
@JetAce08 how would computational flow analysis help this process??
circusboy90210 1 year ago
@circusboy90210 well, the combustion chamber in a jet engine purpose is to heat the dilution (extra air unused in the combustion process) and expand it, bringing the super high temp, low volume air flow to medium temp, high volume of air flow used in the turbine. By using computational flow analyses one could maximize the efficiency of the combustion and expansion process in the combustor and improve things like fuel efficiency, emissions production and maintain a smooth, fast flowing air
JetAce08 1 year ago
@circusboy90210 (cont.) stream through the combustor, maximizing overall thrust. Im sure GE used it in the development of their "TAPS" combustor, which is the newest, most efficient design of full annular combustor to date. It could and most likely was used in atomizing fuel nozzle design. Basically computational flow analyses could be used in the whole turbine engine design, not just the combustor as I have made.

I'll have to agree wholehertedly with 05u16hep... my advice to you is to first of all get your A&P license. get next to em work on em get familiar with em and then you can work your way back to design and engineering. I'm an AMT and to clear up any confusion, the diffuser takes fast moving compressed air strightens it out, slows down pressurized air before combustion, it is the nozzle thru which hot expanded F/A mixture is forced through is where the thrust is generated.

@mikester105 thanks, its gettin hard to keep designing and building now that im in the marine corps. A barracks room is not much good for building that kind of stuff. Im aiming to be a fuel technician for nasa when i get out since my job is cryogenics now. Im goin to continue building as much as i can for the next 4 years, which wont be much, but when I get out Im goin to build a turbocharger jet engine, as ive wanted to since middle school.
JetAce08 1 year ago
In the early days, a European mob built an aircraft that used a piston engine to drive a turbofan then a fuel-oil was injected and ignited, this produced thrust, enough to get the craft airborn, your concept works, if you were to restrict the exhaust and then use propane as a starter fuel then inject kerosene you may get an interesting result, However if you do this, PLEASE BE CAREFUL,

that wont produce any thrust... when does a blowtorch become a jet engine?
u need slow, compressed air to get a good burn, plus you need to give it a smaller amount of space to burn in to actually produce thrust: jet engines are very difficult to make
05u16hep 2 years ago 6
@05u16hep i didnt say it was a 'jet engine'. i said it was a jet engine"combustion chamber" which is exactly what it was designed from. and yes you are right, it doesn't produce much thrust, then again, combustion chambers dont. The compressor is what produces most of a jets thrust. Also 'slow' air is what you dont want, the slower it is, the less expansion comes from the burn.

here's what i did I took a soup can like u have here, drilled a 3/8in hole and reamed it so that i could fit a 1/4in barbed hose fitting in. (it'll thread it self in.) i connected a hose to the fitting, that hose went to a 3 way compression fitting were the compressed air came in also on top of the tee fitting there was a psi guage that i could unscrew and put a funnle in to fill with gas. so yeh i did that barly turned on the air lit it with a torch..flames....turned on the air more & trust!!!

@samuelm77 , thats not a jet engine, not even close, its just a pathetic attempt to make a torch...
And the combustion chamber above is not an actual combustion chamber for a jet engine. I dont know what kind of fuel your using but its probably not the right kind, flames should NEVER come out of the combustion chamber....
Fonzy4101 1 year ago
ok do you have any tips. because im using orange peels in the combustian tank and wd-40 to ignite it with an air pump. i need a compressor fan but i dnt have one
samuelm77 1 year ago
Orange peals in the combustion chamber????? WD-40 and an air pump ignition????? HUH????? Your not even close to making a jet engine.... For you i would suggest making a beer can jet, just google "beer can jet instructables" and click on the first link.
The only way for the average person to make a real jet engine is to use a turbocharger. If your really interested then search "DIY Gas Turbine" although for someone your age it would be extremely difficult just to understand the concept....
