more fuel! bigger hosing

this guy may be the new integza

Combustion chamber looks undersized. And perhaps the intake is a little too big? You are close though.

when the acrylic is being burned is it ok to smell the fumes if they are even being discharged ?

'working jet engine" ...you might want to check if you have the right definition of working...

I dont know a lot about these engines but i tought that if you would try to make a «choke» system that controls the air that enters, maybe you would be able to start it beacause maybe there is too much air and it blows the flame up at the beginning

Coulda gotten away with a nut instead of that adapter

I have made one with but it’s just a pipe and a can

Good job for a young man 💪👍

The issue that you are having is clackers you have two exit points for the exaust

genius

do you know what slag inclusion is🤣

What height voltage generator did you get

Great video! Hope you're having a good day. Can I ask what formula you used to determine the length of the exhaust and the combustion chamber?

Where you from james? I love your videos bro keep up the awesome work!! Great job 👏

crimp the end dont drill small holes and the crimped input should face the intake. it will work

Working? 😂

Shoulda used 7024

Also, Pulse jet engine update??! maybe!?!!

Please keep trying to make these!

Imagine you gift this to your grandparents, "ARGHHHH MY HANDSSSS"

Finally a good channel that explained EVERYTHING and shows the whole process!!! so underrated!!!!

А клапана там не должно разве быть?

add a tesla valve to the intake.

Good job on your efforts. Messerschmidt could have used you on his development team for the argus back in the day!

You need to manage the fuel-air mixture, and I think a check valve at the intake would help

Hey Judson, Random thought, but could the reason you are not getting a self sustaining combustion be the placement of your intake? With the intake in the place that it is, the shortest path between intake and exhaust does not cross the ignition. If you were to swap the placements of the intake and the ignition would that make a difference? Your fellow teen, Jerry

Avoid the cutting and welding. Use plumbing fittings. See my video "pulse jet from plumbing fittingsgs"

I'm studying jet engines. RUclipsrs like you should be known to the world I've watched a lot of videos, but I'm the first person to explain it so easily. I'll give it a try Before that, I'll have to learn welding skills!

That was pretty badass ngl.. Keep it up and This typa creativity will get u somewhere homie🗣🤘🏼

i like pulse jet

To be honest (and from my very limited experience), when a pulse jet starts up and only sustains with compressed air, it almost always boils down to a geometry problem. For example exhaust too long/short (which you tried), intake too far back/forward, needs more than 1 intake, fuel injector/spark in the wrong place, combustion chamber too small, intake/exhaust area too small/large, etc. No guarantees that any of these will help but that's what I'm inclined to thing. Also maybe braze the copper tube onto the jet to help with better heating of the fuel

Good afternoon, you need to increase the volume of the mixing chamber and reduce the diameter of the exhaust pipe

I'm curious as to why you shortened the combustion chamber. Is there a formula for length opposed to radius? Or, did you just wing it?

How you Build this

You need more viewers and subscribers

Very cool to see this. Keep experimenting and learning. I spent my youth in my parents basement building model airplanes and learning about machining and welding. 40 years as a self employed machinist is the result.

HEY @James Judson, i have built a few now and a few recommendations for you to help get it running: 1. I noticed towards the end you had a mig, id recommend using that for all the welds, there shouldnt be any extra lip on the inside of the engine because it will upset the natural flow which is what the engine depends on to sustain running because it goes off acoustic resonance of the detenation. 2. The length and shape of the exhaust compared to the combustion chamber and intake is also important. 3. Fuel injection positioning is also important. They are a fun project, but not a toy so stay careful because it can be dangerous if you neglect safety and precaution. You can do it. You almost have it. The inner dimensions are very important with proportions and cleanliness of the joints and they can make or break it. Make sure to not leave the flow regulator on the hose from the bbq because it restricts the flow to much and will block the flow if the combustion triggers the safety valve. One more thing, try turning your propane tank upside down so it feeds liquid propane into the thing giving it more fuel to use, and it also will run better once in a hotter state so if you need to run it best you can to heat it up then try going for full on run.

Heck of a job! Great video.

I made a pulse jet when I was 16 years old. I am now 73. You need I moving part, a petal valve, fitted between the fuel input and the combustion chamber. I made mine from razor blade steel.

Cleanliness when welding is key.. even small amounts of paint (or any contaminants - oil, rust etc) close to the weld cause chicken shit welds. I would say that is the main reason you struggled to get nice welds - poor preparation.

At least you tried and it wasn't a failure but, a steeping stone in your next project! You go James!

To get your pulse jet running, you just need to get the air to fuel mixture and the pressure right. I buildt my fuel line out of an old breaking line, you have to get the diameter of the nozzle juat right and things will get way easier. Good luck and keep building!

Keep it up!

What fuel did you use

try a shorter exhaust to constricting, for your welds try a mig or a join the dots approach with a 5 mm gap between the dots,. just keep going around till it all welded keep trying you'll get there

I have been " Skilled Trades" for roughly 40 years. I am absolutly impressed with your knowledge of hand tools and fabrication. Keep hitting it, learn grow and get porficient. You are going places in this world.

Lol i bet that jb weld smelt awesome when hot
