I turned my Fan into a Jet Engine (3D Printed EDF Afterburner) 

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

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

A centrifugal?

Brrrrr

Lol

😂

But I'm a turbofan jet engine

sounds like a normal fan to me

@@dumbteens348 Because it is.

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

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.

Have to say, so did i !!

Same 🤣

Ditto

Made my day

@@TabletopTitans. He won a father unlike you

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?

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.

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

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

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.

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

xD

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!

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

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).

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

Makes sense...does it take longer though?

​@@jonspeidel​I 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

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.

There was no coolant there, right

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.

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 =]

Colin Furze has you covered!

When he added the 2nd tube i thought about "appliance for cutting holes into walls" ...

@@claudiusraphael9423 It's like those lasers that people use to cut glass in movies....only a lot less sneaky...

@MADALITSO BANDA Yea really : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QxpHJipB67g.html :-)

Top gear tried a pulsejet rotisserie chicken

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.

That’s integza for ya

I think it’s the attic.

This dude could have a mr rogers like tv show for kids and kill it

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

FBI: *knoks door*

@@airfighterxgg3559 Haha

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...

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-toVfvRhWbj8.html

that would be very cool, yes.

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

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.

How has he not noticed your comment... lol Edit: he noticed it

Awesome stuff! Collab?

Yeah

This dude is cool as heck!

@@ezrarichardson279 cooking chicken with jet engine

i was about to say the same thing

David actually commented on this video and had some suggestions!

Ye

denied

Nono agrees

I totally watched the same Veritasium video and made the same comment like 20 minutes after you.

@@Newtonml yeah when they started talking about the pipes in the engine i remembered how they use the fuel to cool the engine, i first found that out when they had to keep repumping the fuel in serial N4 i think, the guy talking over explained that fuel was used to cool the engine.

Some rocket nozzles are cooled by the fuel like integza does But there are oxigen cooled nozzles

Why not loop the cold liquid fuel instead of water? It’s more efficient and is more realistic.

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

When he gets about 140 db out of it. THEN it'll start sounding like an afterburner,
