[@lvdox21]

Pro tip, when you cut fuel in your engine, you’ll want to spin the compressor fan for a few moments after to run air through the engine. This helps it cool down and prolong the life span. Also if you want to film inside your engine and not burn the microphone, put a mirror in line with the exhaust port and angle it with a camera so you don’t burn the camera. The exhaust is pointed at a mirror

[@DantevanGemert]

The microphone also sounds a bit off 😬

[@desertfresh3740]

Another thing to add about the heat: Jets and turbines are cooled by the air in the engine. Increasing fuel without increasing airflow causes an increase in combustion temps. So if it's running too hot, increase airflow.

[@loueptus5265]

Big brain time

[@rudraigh]

@@desertfresh3740 Huh! I haven't done the research on jet engines but for piston engines it's exactly the opposite. Its the fuel that cools the engine, not the air. In fact, too lean of a mixture can burn the electrodes right off a spark plug whereas too rich of a mixture cools the engine so much that you foul the plugs. Liquid cools much better than air which is why almost all other ICEs are liquid cooled rather than air cooled.

It looks like the engine would benefit from some sort of restriction at the exhaust as to increase the escaping gas velocity, assuming you can keep compression high enough at the intake. Some sort of a CD Nozzle should be pretty simple if you made out of a can or something, especially with that spot welder.

[@cailco100]

depends on how fast he exhaust gas are traveling sub-sonic and yes it can benefit from it. Supersonic and ya you'd decrease the gas velocity and lower efficiency.

[@brennenbranger1897]

@Eric C the effective momentum of the gas is Mass * Velocity^2. While increasing both is beneficial, increasing the velocity of the exiting gasses is much more beneficial than increasing the mass.

[@snortiblog]

@Eric C I completely forgot about the mass flow rate of the system, but too be fair, if the exit speed of the exhaust for engines like this was inconsequential, then why do CD (or just converging) nozzles exist at all? As much as increasing the mass flow would also increase thrust, it would require a new compressor design, or stronger motors. Assuming that this isn’t cost effective for a moment, by optimising the velocity of the exhaust for the given mass flow rate, he would also in turn optimise the thrust output of the engine (as this increases the kinetic energy of the exhaust). As rocket engines are virtually the same as jet engines in this manner (they are both accelerating a gas to achieve a thrust), you can note that this isn’t just the effect of a turbine (as rocket engines do not have a turbine).

[@jakegarrett8109]

@@cailco100 You still use a nozzle (expansion nozzle) if its supersonic though... You can also tell just by looking at it that its not supersonic, but obviously it is just due to the extremely poor amount of thrust as well. Either way, nozzle is good both supersonic and subsonic.

So…next you need to add a bypass to it to allow most of the air taken in to bypass the combustion and mix back in afterwards. This will increase the thrust produced and is why turbo jet engines are designed so. Also lowers the noise

[@ChucksSEADnDEAD]

That's a turbofan.

[@Steve211Ucdhihifvshi]

Mate go youtube jet engines compared and explained.

[@barongerhardt]

​@@jeffstrongman7889 We typically only see afterburners on low bypass turbofans, turbojets and non-turbo types of jets. In most cases effectiveness will depend on how lean the main combustion is. In turbo type jets, lean mixes (like 4x more air as needed or even higher), to keep temps down, preventing damage to the in exhaust portions of the turbo mechanism. This leaves plenty of oxygen to add more fuel to and burn after those more fragile components. This inefficiently adds power. In a low bypass turbofan the bypass air can be mixed in with the hot flow, or not. There are real world examples of all three (hot only, cold only, the mix) being used for an afterburner. In this case, the simple jet doesn't have a turbo. It would likely be more power and fuel efficient to tune the main combustion closer to an ideal mix. I would also guess that the current build is running fuel rich. So there isn't any excess oxygen to use in a secondary burn, but that is just a guess.

@@barongerhardt I was talking about OP's example, not the proposed experiment.

@@ChucksSEADnDEAD That's fair. Your terse answer left some ambiguity in my mind, but I agree. What OP described was what most would classify as a turbo fan and they called it a turbo jet, but it would still be a sub class of turbo jet; if it had a turbo. I guess my problem, to me; for both, op and you; is that the video didn't have a turbo. So OP was wrong, but you didn't really correct it, but took it in another direction. Sorry for the rambling. My guess is that you know what you are writing about, but most, even most on a nerd channel like this, don't know that much about these terms.

@@APLANEDUDEYT in a regular jet engine the combustion turns a turbine which in turn turns the compressor and the fan right?

As someone who takes thermodynamics, I can say that you summed up the theory very well, would've appreciated to see an explanation of how expansion and compression is isentropic (meaning zero change in entropy, or just incredibly efficient), and heat addition and removal is constant pressure, and unfortunately it's hard to call this a jet engine, more or less a ducted fan with an overpowered afterburner. If you really want to make this a jet engine, you'll have to create the correct geometries so that the fuel and air can be ignited with a constant pressure, and the compressor, and more specifically your expansion process can follow a more isentropic curve. Also, your compressor isn't much of a compressor really, it just accelerates air and then heavily restricts flow, which just increases entropy really. If you want to make this more efficient, and potentially fly something, and believe me I've given this type of heat engine a lot of thought you need to do 4 things: - Compressor, make a 3d printed in your case, more preferably with titanium sls, or milled titanium, with multiple sets of blades (i'd recommend just copying blade geometry from existing turbojet designs) with an increasing inner diameters so that air is smoothly compressed which will greatly reduce your entropy generation, and achieve a much higher pressure. Also, make sure the tips of you blade do not exceed mach 0.9, I ran the calculations earlier and with a 10s 400kv motor, I think that made a blade diameter of like 150-200 mm, this of course would be the most efficient set up for isentropic expansion - heat addition, id recommend changing what type of fuel is injected and how it is, personally i'd recommend isopropyl,99.9 percent because it is cheap and easy to acquire but has a very large energy density, similar to kerosene, but burns at a lower temp. Youll need to create a way to push the isopropyl through small holes to atomize it, so it can combine perfectly with the air and allow for a constant pressure heat addition (which you'll also need to model geometry for), and increase efficiency - Expansion, this really is just all geometry based, and with your knowledge of rocket engines you should be able to figure out how to turn high pressure zero velocity air into low pressure high velocity air. Good luck I hope you revisit this, this is a very cool project and the engineering behind jet engines is very fascinating, also screw tomatoes also fun little bit of thermodynamics: Work (net) of a breyton cycle turbine is equal to Qout - work (compressor), what you're doing here is maximizing Qout by making all the compressor work be from the electric motor

[@kenwillekens9894]

Integza make a sugar rocket using carbon so it flies well

Video idea: make a drone-type rocket. instead of a normal drone using four wings, you can use 4 small rockets to fly it. It would be pretty interesting to watch

[@kkadz]

8:54 LOL, when you were doing the soldering at like 2:25 i was thinking about how i wasn't sure if they were gonna hold because of the heat. that's so funny. thanks, i've always wanted to see that happen

Video idea: a small jet powered merry go round, or a smaller version of an amusement park ride! Give something already fun, the Integza flare !!

[@MistyShadows]

I was really wondering how much thrust it was producing with just the electric fan. How much of a difference does the rocket part actually make?

[@Skiballer]

The fan probably contributed pretty much none of the thrust

[@jakegarrett8109]

@@Skiballer I wonder if he used a normal EDF, my little 70mm (below 3") EDF is rated for over 2 KG of thrust (so with 2 of them the skateboard would be accelerating as fast as if you dropped it off a building). I don't know if the flame would be helping much with that much flow rate, but it would be cool to see.

[@tianming.]

wasn't edf just an impeller

[@jakegarrett8109]

@@tianming. EDF is indeed "Electric Ducted Fan", yes, they are quite a bit more powerful since they are axial fans compared to inefficient centrifugal fan with afterburner (but he is just making it for fun, so its not a big deal that its super weak)

[@f.a3202]

@@jakegarrett8109 The problem with EDF's is that they can't produce high pressure flow but high speed flow and that's why it wouldn't work with an EDF. He actually demonstrated this in a video called turbocharged pulse jet or something

[@badamancraig]

For your next engine, you could use gears to turn the compressor and a 'ratchet' style clutch to turn the compressor. Then, you could run a center axle and an exhaust turbine! Once the turbine is turning at a greater RPM than the electric motor, it would turn the compressor instead thanks to the ratchet! Then you may have a fully self sustaining gas turbine! Would definitely need remote fuel cut off for safety though :D

[@blake_niewoonder]

I have a few ideas on how to further improve the engine. If you look at your footage, you can see that the engine gets very hot, almost white hot. You could make a bypass fan on the front and a shroud to channel air over that hot area to help keep it cool. Also, you could re accelerate the air after it is ignited to make it go even faster. Just a few ideas to consider. Great video!

[@dperreno]

A bypass fan would require a turbine to drive the fan which was the one thing that he "simplified" out of his design by using an electric fan for the compressor. This is a hybrid jet engine (not even technically a turbo-jet, since no turbine), so he would have to add both a turbine and a fan, and at that point he may as well add a turbo-compressor...

[@blake_niewoonder]

@@dperreno I'm not saying a turbine has to drive it. Just make a driveshaft that can connect everything throughout the engine. Everything would still be driven by the electric motor, there would just be more fans.

Theme for a future video: 3D print an electrolysis tank to split water into hydrogen and oxygen, then use then results to build a combustion chamber that has only water as its byproduct. No carbon to offset!

For being a Jet Turbine powered skateboard, it's amazingly slow. Lots of coloured flames, noise and heat, not much actual thrust though, amazingly so. It's a firework.

[@RocketkidDesigns]

Video Idea: try redesigning the compressor stage to resemble an automotive centrifugal supercharger. I've always wanted to see if a 3D printed compressor wheel could actually generate pressure, and since the intake would be perpendicular to the thrust all the forward thrust would be from the jet engine.

[@debjennings4686]

Nice work! I think the engine needs more compression, that flame was very big 😊

0:19 *WHO IS THIS MAN, AND WHAT HAS HE DONE WITH INTEGZA?!* I can't accurately describe in this comment the noises I made when I saw that shaved face, but I can at least say that they were many and pained and filled with despair

[@element9224]

You should try to make an underwater rocket engine. It would be a good next step to get to mars, considering there is no air in space. You could use electrolysis to get an oxygen and hydrogen mixture as fuel, or you could just buy an oxygen tank and continue to use butane.

[@snortiblog]

An underwater rocket engine is actually the opposite to what is needed in space, as space is a vacuum (very little to no pressure), and water is under a lot of pressure (at least in earths oceans it is), so the exhaust needs to be at vastly different pressures (otherwise the exhaust might be pushed back into the rocket). Sounds like a cool idea though, if he were to combine it with some sort of supercavitating submarine maybe he could make a supersonic sub.

[@element9224]

@@snortiblog good point, although I was thinking smaller scale where he just mounts the engine under water cause I imagine an entire sub would be too big of a project for one video. But with pressure in mind it would probably be best to keep the engine as close to the surface as possible while he is prototyping.

[@AVIONADE]

Try to re-combust the exhaust gas to make even more thrust (basically add an afterburner) and make the nozzle a bit smaller to increase the overall pressure, hence increasing the exhaust velocity and also thrust. I know the afterburner is a very much overkill but yea- it'd be cool.

[@fortheboys2724]

[@wakeutainment-l6n]

BTW I love the genius of pushing flammable liquid or any gas for that matter through a chamber using an electric motor and hand made components. While you were making the pilot holes, I thought why not use a regular stove gas burner as the pilot but you would have to keep it vertical so the flame doesn't die out, and then I thought it could be done if you can place the gas burner then build a 90 degree bent metal tube where the flames would shout out from. Just an idea, so thought I'd share, being the least we can do for the entertaining video. Keep up the great job, hope to collab soon!

[@Tamb899]

Video Idea: I think in will be funny if you try to mount the engine on a little boat, put that in a lake and try to make it working! P.S. I am a big fan of you and really interested in model rocketry! So happy that you decided to make rockets, can't wait new video's! 😃😃

You could try to make a rocket powered glider. 3d print a glider plane (like the space shuttle) and launch it using some kind of solid fuel rockets (loke the sugar ones) and then make it glide down to the ground using only it's potential energy. It could be cool to see it in FPV using an small camera or so.

[@edfhobbies556]

NICE !! This looks like an after burner vs a "jet" even though the combustion happens in a true combustion chamber. You could measure thrust from fan without AB and with to measure if AB gives more thrust a lot of times with EDF the flow of air is disrupted by gases instead of gasses adding to static thrust and efflux

[@Chris47368]
