BRB, gonna make 20 of these and attach them to my paramotor
Ah yes. The FAA would love you if you did that.
Hello Peter big fan of your electric plane 👍
Or just a big electric ducted fan on your ultralight plane.
Eagerly waiting for you to do so Peter👍
I really hope you're not joking ahahaha
If my car ever runs out of gas, I hope Integza pulls up and asks: "are you out of fuel my darling?"
I will! Im always watching. Always!
Lmao!!
@@integza im scared :(
@@integza "ladies and gentlemen, we got him"
@@integza tomatoes are discusting Kill one with this And make a proper after burner
You actually don’t want a centrifugal fan (that pulls air in from the front and directs it sideways). What you actually want is an axial fan (it pulls air in from the front and sends it out the back).
sounds like a normal fan to me
@@dumbteens348 Because it is.
The angry sound while the CNC is removing material is due to the long length of the bit causing chatter. If your end mill is further into the collet, it should help. I’m not sure if you’re manually putting in feeds/speeds or if the CNC is calculating it, but it could also be that you need a higher or lower spindle RPM or feed rate. Hope this helps in the future!
I am a fan
A centrifugal?
Brrrrr
Lol
😂
But I'm a turbofan jet engine
Video idea: make this on a plane! The thrust seems to be good enough. And it can be made easily by attaching wings to it!
Yes, He can Do it
David Windestål already did that once on an old episode of flitetest.
He could but you have to perfect the aerodynamicist so then it would actually fly in that just stay on the ground or get up in the air then do a nose dive
@@multimotionz2952 If you just have enough power you can make a closet door fly. You only need a powerful motor on one end and flaps on the other... (ailerons and elevator can be combined with some electronics calculating)
Try to partner with PeterStripol and make a plane! It should be a great first step to building model rockets with these
Made on of these about 30 years ago using exhaust pipe scraps to melt aluminum in a kiln, also used it to warm up a cold winter basement, firing this up would heat a cold basement in very few minutes to comfortable. Brought back some fun memories.
the satisfaction of having a print come out well is definitely a joy
I‘d recommend to use (lots of) ethanol as a lubricate when working on aluminium parts. That makes the surfaces smooth and protects the tools.
Ethanol residue + fire seems like a poor combination if you don't wan't flash fires.
@@lastwymsi better use kerosene then
@@lastwymsi pretty sure ethanol evaporates really good
An ethanol plus water based misting solution is what a lot of sign makers use when cutting aluminum
@@justinmorris8582 yes, that‘s what I mean. In Germany we call it „Brennspiritus“ = denatured alcohol, it‘s cheap and works perfect for drilling, honing or filing aluminum. For filing there is a little trick: First file across a piece of chalk, then wet it with denatured alcohol. The chalk will keep the alcohol longer in place. Trick No. 2: Use chalk only when filing iron or steel, this works also like a lubricant.
When you said “l think the can is empty” and picked up the drill, my first thought was Oh Fark here comes a Darwin Award.
Have to say, so did i !!
Same 🤣

@@TabletopTitans. He won a father unlike you
Hey you need to find a friend who's into glass blowing and switch from plexiglas to real glass! PS you might want to add some temperature probes to see where the hot and cold spots are happening; I did this when testing vaporizing burners and it really helped. PPS you need to use cutting fluid when machining metals: your cutters will cut faster and last longer. :-)
I love how you get to all the design issues some of them in a much different order than I would have but you seem to be adapting a very basic design to a more modern one
Couple of things I noticed (potential video idea?) 1) try injecting the fuel at the front (nearest the fan) of the flame tube, so it has a better chance of lighting and staying lit. I saw a lot of unburned fuel was just hanging around inside the engine. 2) Jet engines actually do use "normal" fans, but have multiple stages (decreasing in size) to compress the air more
ty, i wanted to say that but didnt know how 😂😂😂
I admire the fact he can even demonstrate this and pull it off. He usually refines later. Nice input though, always good to see people in the know/experienced sharing as such. Cheers.
Those normal fans are not normal at all. They have a rotor and a stator assembly which generates pulsed pressurized air. That's why they are called compressors and that's why they have lots of stages - the flow is constantly redirected to enter the next compressor fan at an optimal angle to be forced down the next stator and rise in pressure. So much so that the fuel spontaneously ignites from the heat the compressed air acquired in the process. You also need a larger exhaust than the combustion chamber intake because JET engines are a constant pressure engine - the process of burning the fuel goes in to expanding the gasses, not increasing pressure to push on a piston. The thrust comes from the larger area the same pressure is pushing at. The higher the compression ratio of the compressor - the more effective is the engine.
i thought the same thing with the compressors, but he is somehow right, small model jet engines mostly use centrifugal compressors to create enough pressure for the rest of the engine. he could just use a radial compressor design for example from grabcad. the main problem for most small compressors is they require lots and lots of rpm to work efficiently.... i hope his motor can reach at least 60.000rpm
Big difference here is that the intake fan and compressors are drive by a turbine at the end and is self driven. Not by and electric motor. He would have to make the compressor and shaft out of aluminum and balance it properly given his current setup.
You should design a rig where you can measure the thrust of your engines
This, would be great to see just how.much thrust these things are outputting, I'm managing a sliding rail with a load sensors
I think he already has that. iirc he had the engine on a straight track and measured how fast it got pushed along it.
He already did that
why is there a ' after engine
@@MarterElectronics we have a grammar Nazi
Adding hot air and adjusting the fan gives you a fantastic result 🎉
You can reduce vibration on your CNC by using higher speeds and the appropriate carbide tooling. 👍tools will also last longer. Also I’m going to recommend a liquid cooling setup when your doing metal.
You need a brass coil to let the liquid butane turn back to a gas, the brass burner rings are not very efficient when there is liquid spraying out. This is the reason you are not getting a consistent flame.
could you elaborate on how a coil would be used? eli5
@@Guy_Reverse Wrap it around part of the combustion chamber, stepping up the diameter of the tubing after the coil to allow for some expansion and to encourage gas to be forced out through the burner ring. Another modification that would be a good idea would be forming the burner in to a fully connected ring with two to three fuel supply lines to it, all of the same length, and with minimal bends. This would give each hole the same pressure and the same possible volume of fuel supply, evening out the shape of the flame to increase the efficiency of the combustion. More efficient combustion makes a more stabile engine and a more powerful engine that is more fuel efficient.
@@KnightsWithoutATable would it be overkill to place the coil inside the combustion chamber? If it's risky it would be perfect for @integza 😜
@@plopnl1 in other tutorials I have seen people put the coil in the combustion chamber, it is quite safe as there is no oxygen in the brass fuel line making an accidental ignition very unlikely. The heat in the combustion chamber turns the liquid fuel into a gas much more efficiently.
@@augustobob That is a good idea, but I think in normal rocket and jet engines they coil a fuel line around the combustion chamber to turn the liquified fuel back into a gaseous state.
Video idea: You should now figure out how to attach this device to any type of vehicle, flying one or just a car and find out how much real trust it have 🥳 Keep in mind that Tomatoes are disgusting! 🤢
Better yet, design it to fit on an available to buy RC Jet so people can mount these on their own planes!
He'd have done this anyway
It doesn’t add that much more thrust but it does a bit, technically ur adding more weight so that’s why weight has to be added to the equation for thrust
Darn. Was gunna suggest this too
probably RC plane could work if it's light weight?
11:20 2000 kw nice „little“ engine you got there ;)
Really love this, took a lot of time to do this❤
Video Idea: You should make a thrust measuring test stand using a load cell and an arduino. This way you can record the precious thrust your rocket / jet engines are producing! This enables you to calculate a lot of interesting variables like thrust to weight ratio, specific impulse, fuel efficiency etc.
You butt! I was gonna say the same thing! Here, have my like.
This was going to be my comment too :) Here you have my like :)
please do this
Yeah I was keen to know how much thrust was generated... oh well I'll have to set fire to my workshop and find out
I’ll be frank, imagine putting these after burners on RC planes, that would be a cool af Project, heck, imagine Integza making actual little rockets and planes out of all his Engine concepts!
I am starting this as a project rn. Two 50 mm edfs with afterburners. We’ll see how this goes.
They won't be able to sell it to kids, so not worth it
It has already been done by some nerds. Search on YT, some projects are really crazy and sound realistic =)
I assume that’s the end goal
Sounds like a PeterSripol collab idea!
Hint from an old machinist, when machining aluminum cbn cutters are amazing. Carbide also works well with the use of a lubricant. Light oils like penetrating oils, wax or water based machining coolants really help. You'll be surprised at the difference in the cutting finish and accuracy.
I was thinking about it when I was young, it's a great experience
Big tip for machining aluminium with out coolant particularly on a lower end machine is to use a single 0-flute up cut bit, it is very forgiving with chip extraction, slow feeds and low rigidity
Makes sense...does it take longer though?
@@jonspeidelI do the same thing... cutting Aluminum on a small machine. Using the right process ends up going faster because you're cutting correctly. You'll break fewer endmills & spend less time cleaning up parts. You can buy a cheap 10-pack of them for $20 from amazon. A way to tell if you're cutting or rubbing is to feel the temperature of the piece your cutting. If it's hot, you're rubbing the metal off, not cutting it. Some of what I could see in the video I see signs it wasn't cutting, it was just rubbing. Also drilling is your friend on a small machine. Drillings material removal rate is much faster then milling, and you're doing a lot less plunge cutting.
Also use the highest spindle speed possible
Could I ask that you start using strain gauges so we can see the amount of thrust you are generating? It would be cool to see how the small changes affect the overall thrust. For the rest, I cannot wait for the next video.
this "engine" only generates the thrust the motor can output. There is no jet engine geometry that makes the expanding gas prefer one direction over the other so it depends on the fan to offset the gas expansion towards exhaust. it is just a flamey fan
@@LiviuGelea Thanks for explaining it so well. I am learning about jet engines by watching Integza.
@@jack-bjorn Watch someone else. his thrust is lacking
@@LiviuGelea exactly. Cool design but calling this a jet engine is pretty clickbait-ey. Its basically just fire inside a tube.
@@jack-bjorn Put the engine on wheels and use a fish scale -- that'll work pretty well. Integza is on a good path -- if the fan can handle higher static pressures, then that fan can keep blowing air into the combustion chamber and you can get more thrust out of it. EDF's don't like high pressures (more of a total moving mass thing), so using that as an afterburner is fraught with problems (not enough "push" to get he flame to move the right way). It's why jet engines have lots of blades and why those who like to make "homebrew" jet engines usually start playing games with turbochargers (centrifugal fans can make more pressure -- figure "pressure" is roughly "n blades x blade width x speed"). You can get 3-5x the "fan thrust" with an afterburner but you really gotta pay attention to the design (hence the variable diameter concentrators on fighter jets). Hey Integza, if you want a higher-static fan that's commercial, look for squirrel cage blower fans -- commonly found in vacuum cleaners, and fireplace box fans. You'll need to look at the flame holder better too -- it's not holding it well enough... The best part about vacuum cleaner fans is that you can usually mount them in 100mm PVC pipe or so and you get a combination fan and gyroscope (you'll see what I mean -- universal motors for high speed so... yeah). Control the speed with a "router speed control" box. If you do it right (220v vacuum), you might be able to get 12-15KW out of it thrust-wise. And you can make an oil burner out of it and do lost-pla casting. But try to do that outside... molten metal doesn't like attics (err... attics don't like molten metal... the metal doesn't care). Heat-wise, you can get ~20-50KW or more (check out the OilBurner or MyFordGuy's channels). And get used to running the fan for a while before and after a test run.... go look at the guy who's running RC Jet engines on different fuels and you'll see that their "controller" has "starting...preheat...operating...cooling...shutdown" -- jets hate "sudden moves" except for rapid unscheduled disassembly (ka-boom).
I'm sitting here watching this and I am fascinated by your efforts, I'm here for the forceable future. All the best in your future projects
I admire your projects, especially your determination in implementing them, despite various mistakes, congratulations and best regards 😀.
Integza: Is genius at 3D modeling Also Integza: mounts fuel source near flame source.
Lmao, thought the same😂
You missed the most important part about fuel, Igniting it!
@@esnevip yeah but not the whole bottle at the same time from heat hitting the bottle from the open flame.
He's good at modeling, not planing
@@silverdagger5751 I hope he doesn’t regret that, he’s one of my favorite science channels
Video idea: You should have a try at some other fuels for the afterburner, like gasoline or alcohol. With the centrifugal fan able to blow lots of air past a venturi, you can have the makings of a fantastic carburetor!
Thanks for sharing this is very awesome you are a beautiful genius
I love the video. Only problem is this is a really neat flame thrower/pseudo ram jet. For it to generate thrust y or must compress the air before you ignite it. The reason after burners work is the additional thrust is generated off the initial thrust off the turbine. With that cnc and the engineering you could make something amazing.
When machining inside cuts, avoid not having to drill with the mill. it's always preferable to enter through a hole or from outside. much fewer vibrations and a better finishing
speeds and feeds as well, the 3 or 4 flute cutter he is using is fine, but he might be trying to move to fast and getting to many vibrations. Also if it is in that cnc program to have a variable speed rate, helps cut down on harmonics
Should also try to mimimize tool stickout.
3:45 the swarf jumps on that downwards jolt, even the chuck/collet gets pushed.
and, he needs to lube...
Don't call that thing a mill please :D have you seen the concentricity of the endmill? XD I would helix down into the material, then i would choose some profit milling (trochoidal) strategy to rough out the pocket. But anyways i would use a lathe to manufacture this specific piece.
Next time bending tube, fill with sand first. It won’t collapse when bending
Especially DRY Sand. If it has slight levels of moisture, it can expand or slightly explode when heating
@@tomstorck9972 you are correct! I oven dry my sand and leave and end open, but you are definitely right. Wet sand BAD!
In plumbing, when bending the chrome or gold plated supply tubes under say, a pedestal bathroom sink (where you don’t want tacky looking braided flex supplies) we slide a tightly woven spring over the tube before bending it to fit. We also have proper hand held tubing benders, but the spring method is way quicker.
@@jbirdmax also correct! I have a tube bending kit I got from K&S metals out of Chicago. They sell TINY hollow and solid tubing. Found the kit at Ace Hardware.
I hope these inputs shared from experienced commenters never end... yeno, in case I decide to buy a 3D printer and CNC machine to make the crazy s*$t which integza makes
Add coolant to your CNC (mixture of oil and water) extra lubrification really helps with the excessive noise and allows removed material to get out of the way resulting in less vibration thus less noise and a prettier finish. Wd40 works too, if you're not in the mood to mix water and oil
You should make a transparent resin 3d printed rotary engine with 3 cylinders. It would be really interesting seeing all three cylinders working together.
I'd like to see you mount the "engine" section on a sled assembly with a simple spring scale and see if the afterburner actually adds any effective thrust...
Yes agreed, I was wanting to know how much thrust compared to the EDF by itself?
The only issue with EDFs is that they don't produce a ton of static thrust. Though I would also love to see how much difference is being made.
@@driftertank Fair point. I agree.
of course it doesnt... its a fan with a silly flame in front of it
@@alistairbalistair9596 You just described a regular jet engine. Also, *behind.
"Now, what happens if I turn it upside down...?" "Oh, that's way too much." "Shut it down!" "NO!" LMFAO
xD
Integza " MATE " you are a legend. Thank you for your video, you help me understand how a jet engine works.
A very detailed and scientific analysis,& aproch,to watching grass grow.. with your own twist to how it relates to some other type of kick azz sience
I do a lot of aluminum machining, there are two thing I think you can do that will help. Only have the cutter sticking out as long as you need, if you reduce that the cutter won’t chatter as much. I also looked like you are cutting the aluminum dry, aluminum needs some kind of lubricant when cutting. Even a couple squirts of WD40 will help a lot.
I was wondering if the feed speed was too much, too. I don't do machining, so I may just be talking out of my butt
@@ericgoldman7533 when it comes to aluminum, it has a tendency to want to stick to the cutter. Cutting oil or CNC coolant prevents a lot of that. To say feeds and speeds is a deep rabbit hole would be an understatement. There is a LOT of variables like how many flutes the cutter has, the angle of flute, if the cutter is carbide, if it has a coating like ZrN (AlTiN is not advisable for aluminum since the coating contains same element as the material and can bond). Rigidity of the cutter in the holder...on and on. I really enjoyed this video a lot, when he was doing the milling - my heart hurt a little because I was thinking, choke up on the cutter a bit more and give it a little squirt of WD and you’ll love it. There is certainly an art to CNC milling, I use SolidWorks to design my parts, BobCad to generate G-Code, my Fadal VMC has expanded memory, converted for WIFI, new inverter, new 10Krpm spindle, blah blah blah. My mentor has a much older and primitive machine and he uses MasterCam on an old Windows 95 pc. A lot of the time, I can’t keep up with him- but that is +30 years more experience than me. If you ever watch Titans of CNC, Titan talks about working your way up to the fast and aggressive cuts. I tend to stay on the very conservative side until I’ve got a proven program (no crashes)- then if I have to do a lot of the same part, I’ll tune the S&F until I hit the limits.
@@triphonikstudio Thanks. While I haven't done any machining, I do have an interest in it, so it's nice to hear feedback from people with experience =]
The peroxide engine was primarily released oxygen, right? Could you revisit that build with an afterburner to improve it's thrust? Second idea: could you modify a spring scale into the base to measure thrust during experiments?
oxygen does not burn
@@iteratortv bruh what
@@DDrac0 imagine that
@@DDrac0 oxygen needs a fuel to combust which the exhaust from the peroxide engine doesn't have which means the after burner won't work
However, if there is anything hot enough to qualify as an ignition source in the path of the gas, pure 02 will *find something to burn*, and uncontrolled O2 fires are terrifying. So, yeah, even though it doesn't work as an afterburner, handling oxygen in the presence of heat/spark/flame is extremely dangerous.
This is such a cool project!
In a jet engine the front fan blades suck in the air like this but they are attached to a shaft that extends into the exhaust, which has more fan blades which are spun faster by the heat of the exhaust, which forces the front blades to turn faster and suck in more air, creating more exhaust in a perpetual cycle until the engine reaches the peak of its power curve
Suggestion for safety: it may not be a good idea to have your fuel container in front of the flame tube; if the acrylic tube is damaged, the flames may reach your fuel line. Great video, and excellent presentation on how a jet engine functions.
Project idea: Recycle 2 old hard disk and build a gimbal (2 axis stabilization) for XLR camera. You'll recycle ♻️ and build something useful for your future video✅
I like it, green project time!
@@trusttech9942 yay, plus he seems to love explaining rotating forces and momentum in videos, that would be a great one to make.
Great video bro thank you.what a great inspiration
Bro ur videos are a blessing for university students..love you bro
Brings back lots of good memories from my FliteTest days. How much current is the glowplug drawing? I like that solution better than the stun gun I used. One of those "arc electric lighters" might be an alternative? A simple solution to heating the gas is to have the fuel line bent in a spiral that goes through the flame. You can kind of see it in this video: kzhead.info/sun/YL6Lf61liHigd58/bejne.html A problem I had was the flame tube being too short which let too much turbulent air into the flame zone which snuffed out the flame. The glowplug solution is also fantastic as it would reignite the fuel after a flameout. Can't wait to see the next video :) Keep up the great work /A long time subscriber
Wow, I love that the crazy Swede is watching this video!!!
Tänkte på din video medans jag såg det här. Tänkte leta fram den för att rekommendera den, men det ser jag inte ut att behöva längre :D.
Ah man, I miss those videos. I hope whatever you are up to these days, you still get to tinker with RC aircraft =D
You never commented on my edf afterburner videos. Big fan. 🥲
miss your flight test days they where exciting times

I always wanted a 3 d printer. Got some good idea. I will tell yo after I get the printer. Thanks.. Love your videos
Love the video I have a creality cr-10 and it worked okay for a little printed about 6 prints sum were decent size but it ended up breaking on me when I was printing a tech deck ramp love the videos man love the creativity
Sling the fuel line around the glow plug to preheat the fuel and ignite the fuel further in the chamber to generate more pressure. The fan needs a little concave shape on the duct to accelerate air speed and pressure. Love it keep it going! I want to see a turbine that actually produces a little bit of thrust from the afterburner :D
yhea i thought about that too. a chamber for the fuel to expand, might also be worth placing the fuel dispersion behind the ignition point instead of in front that way the airspeed from the fan will help to disperse the fuel and create a better fuel to air mixture. i also think he isnt getting enough fuel into the engine, this can be seen when he's increasing the fan speed and the flame dies out.
@emptyforrest Exactly! The flame tube should consist of two tubes . the outer one should have larger holes to disperse the fuel. the inner one should contain the preheat fuel line which should then disperse the fuel in the outer chanber. But that may produce some overheating problems i´m not entirely sure about that. @integza should try that out...
Best way to heat your fuel is to run it around your electric motor in brass or copper tubing, provides cooling for the motor and hearts fuel toward the combustion chamber. This is an awesome project by the way!
For the next version try to measure the thrust generated, it'd be interesting compare just the fan versus with the afterburner running!
The same resoults the only thing he did is push the burning fuel by a fan matter of fact it might be worse than just straight up fan
Very informative and educative, thank lots ❤❤❤
"two thousand kilowatts in power, I know, it's an overkill" Now imagine the fan with an actual two thousand kilowatt motor. Just evacuate the city first.
As a diesel tech of 15 years, I'd like to see a video on scavenging and the venturi effect. There is a small gap of time as the piston moves down on the intake stroke where the exhaust valve is open, and the fresh air moving in past the intake valve creates a scavenging effect on the exhaust moving out. You also will find a venturi on the exhaust pipe itself that seemingly creates power out of thin air, and I think I understand how it works but it would be awesome to do a video on why!
That is also used on alot of performance gasoline engines, called overlap, top fuel does this as well, but on the exhaust stroke so as the exhaust going out sucks in the a/f mixture while the intake valve is open with the exhaust valve. Engines are nothing more than an air pump..pretty cool stuff
Great....let's us know when you make the vid!
Valve Overlap is used to purge the cylinder for a fresh intake charge, in turn creating greater volumetric efficiency.
watch this video by smarter every day that explains everything, thank me later. kzhead.info/sun/p9OPltqKn4mYnXA/bejne.html
Dude , you rule , love your style and knowledge
Thats really informative 😀
I love seeing that transition of your channel from "I'm 3D printing stuff that burns itself, and tomatoes" to "Let's CNC those hot parts so that it lasts long enough to burn the house too"
You should try adding a oxidizer with the fuel (something like nitrous oxide or concentrated oxygen). I'd be interested to see if it improves any!
He is burning fuel rich but that’s in part due to how his intake is design (centrifugal was a poor replacement) and too much fuel input. It not only starved the flame of oxygen but iced the tubes which restricted fuel flow only for it to then heat up due to lack of flow and ice melt and so the cycle went. Orange flames and the smell mentioned should have clued him into this issue. He needs better fuel control, better air intake fan design, and a section of the fuel coil in the path of the flame to preheat it. All of this would help prevent those issue
This video just gave me an idea. Retrofitting a flintlock with your igniter for a spin on an old weapon. Might use that in my upcoming DnD game
Great video. CNC machining, for low torque/hobby machines, drill a hole first and drop the endmill in that hole to start and reduce the length out of the collet to the least possible (better to have to increase length when you go deeper but this will help with rigidity).
"Jet engines make me hungry." The only logical thing for you to make is a BBQ cooking setup with the jet engine. You can use it to toast a delicious sandwich while scorching tomatoes into oblivion!
Colin Furze has you covered!

Congratulations on an awesome youtube channel, almost a million subs!!
I have heard about your invention and it is the dest ,actions speak better than words
When machining on the concrete, shorten upon yhe cutter as much as possible. It will not chatter so much. Use a 2 flute high helix. Good luck. Love your videos. Dale
I remember when Flite Test and David Windestal did this to hilarious consequence a while ago. Nice to see your take - I'll expect mach diamonds from supersonic flow somehow within the week, lol As for a new project, tomato impactor rocket sled. Rockets, high speeds, and tomato destruction all in one go. What's not to love?
i was about to say the same thing
David actually commented on this video and had some suggestions!
Congratulations on the sustained firing test. You tried and did a satisfactory job.
In a follow-up video maybe you can figure out at what temperature water breaks down into its component hydrogen oxygen parts and use those parts as a fuel and oxygen supply for a small rocket engine
I must admit, his projects start to look professional Oh yeah: once you got a working jet engine, can you stick it on an aircraft or hydrofoil?
that would be very cool, yes.
Anyone else concerned with the fact that he seems to be running an after burner in his living room?

I think it’s the attic.
2:53, for those who dont know. Glow plugs are used in Desil engines when the engine is Cold to Increse the temp in the Cylinder so Normal Function can occour Until the Engine Tenp gets up high enough for the Engine to do it Naturally. Then it Disables its self.

Check out the one Tech Ingredients made. It's incredible
Thats the coolest thing I've ever seen
So far I have seen you building so mano experimantal jet engines but an you create one that produces a lot of thrust (very powerful
Some jet engine tips: Work on making a convergent divergent nozzle out the back in addition to a vane pack to stabilize the air before it goes into your augmentor/after burner. These will help the flame hold steady and lead to better combustion.

7:00 The heck am I listening to ? Very interesting choice in music I see
Project Idea: Build a small chemistry lab wich produces your own Potassium Nitrate (KNO3) for Sugar rockets!
FBI: *knoks door*
@@airfighterxgg3559 Haha
this guy is crazy amazing.
This is really cool. I want more with solid rockets! I kinda want to try to build one and I want to see more testing of propellants. please😄
The only thing wrong with it was that you were using a butane can by itself as your fuel source. You have to regulate your fuel source. If you get a butane torch. Take it apart and remove the striker. Fill your torch rezivior with the butane can. Then you'll be able to use your Servo to jog the valve stem that opens and closes the gas flow to the torch head. The torch head will restrict the flow so that all of the liquid butane will exit as a vapor. The can upside down delivers a combination of liquid and vapor because it has such a big hole to exit. This is why you Ran out of fuel so fast. Using the torch the fuel comes out in a fine mist and vapor which will be way more efficient. You could have done the entire video and only used a half of a can of butane just by running it through the torch as a regulator. Try it. I guarantee you will get a roaring afterburner just by regulating the gas. Cost you 10-15 bucks for a good Large refillable butane torch. 👍😏
video idea : add a carburetor between the fuel bottle and the enegine
I don't think you need that with a jet. The "carb" is the engine, it's what the airflow and everything is for. At least I'm 99% certain
@@Enderbro3300 A valve is reccomended
2:54 diesel engine ignition provided by the high pressure not the #glow_plug the glow plug only used for making the air on chamber of the cylinders hot to facilitate the start engine
Mad intelligence, inspiration for success through the failures and experiments
You really need to have a play around with expansions ratios, it should help a lot in your goal for thrust!
yawn
@@alistairbalistair9596 It would be the same format and he can use whichever sort of engine he likes, I just think he needs to do some calculations so he can optimise the thrust of his engines.
@@fives6487 you peeps aint got no clue
This was awesome. The overall assembly is also asthetically pleasing so it was nice that it didn't completely destroy itself in the end.
You made my day
Try to compress the fuel air mixture before ignition and try to reduce the fuel amount. I can see red flames and that means that the mixture is rich in fuel and the combustion is not efficient. In addition try to use the glow plug after the fuel injector because after ignition the flames will keep the high temp in the glow plug so you can turn off the power (see ethanol 2-stroke engines)
