I grew up along your jet engine projects. Great to see you've finally made it!

Finally, verfolge dieses Projekt schon von Anfang an. Vom aller ersten Testrun der ersten Revision. Und jetzt endlich, nach 11 Jahren läuft das Ding haha, Nice Work !!!!!

Congrats guys! No feeling better than hearing it pitch up in RPM on it's own!

Outstanding work man... Upgrade to an electric fuel pump with a pressure / flow regulator. that will help tremendously.

now try to make one using a full turbocharger rotor with a radial turbine :D

I love this project! Keep up the good work. Maybe adding a cooling mechanism with air or water vapor or oil could help with the turbine overheating?

Ich bin glaube ich erst seit der V3 dabei, aber es ist super jeden Schritt in dem Projekt verfolgen zu können und ich bin echt gespannt was die Turbine am Ende leisten kann.

Ich finde das super Cool das sie läuft. Super Leistung

I have been thinking about designing a jet but based on the thinking in the smallest private jet engines like Williams FJ33 and P&W610f which are two-shaft turbofan engines. Yours seems to be along the thinking of engines used for model planes which I'm guessing will tend to be inefficient. The smallest turbofan engines are for planes around 2.5ton and each engine costs 1million dollars and it's possible to make planes 5x lighter than that which would need engines weighing about 15kg with 100kg thrust. Such that small private planes could have jet speed yet cost very little. Jets are after all relatively simple and a 15kg engine should not cost anywhere close to a million. I think 3D metal printing is a great enabler that makes the convoluted shapes inside the jet suddenly very easy. And good CAD software that can do the CFD calculations for a jet could be quite potent as well. Pick the blade shapes and angles. There is a great deficit in aviation in small planes, there are indiana jones propeller planes still, it's worse than the cuban car situation. A good small turbofan engine could instantly be a 100million dollar business.

Bin auch von Anfang an mit dabei. Die Blechdosen Turbine war sehr gut. Aber super das du es nochmal Richtig probierst

Do more tests!

Saubere Arbeit! Anscheinend muss man noch an einer konstanten Treibstoffzufuhr arbeiten.

DUDE after MANY years of following this channel, from 10 or so years ago, watched every update on the jet, and hearing it finally go up in pitch without the starter was quite the joy! After a decade the mad lads actually did it!

@michaelnorrgren747 vor 13 Stunden Gut gemacht, so schön anzusehen!! Aber Sie müssen Kerosin oder A1-Flugzeugtreibstoff einspritzen! Dann erhalten Sie die richtige Leistung! Das Gas ist nur zum aufheizen.Glaub doch dem Michael.

When you guys scream things like schmetterling und streichholzschachtel it sounds as if someones life is about end.

Been watching this since highschool, now I'm an engineering grad student

hell yeah nice

Its really good to see this project alive. This one was actually my teenage passion and I really wanted to see you guys make a self running jet engine and somehow it showed up on my main feed! Now im in mid-20's but still this one lits up a flame in my mind. Thanks for the great contents

Well done! I'm so proud of your tenacity to keep going! Is this the original turbine wheel you used years ago?

Congratulations on your progress! I've been keeping up with this project ever since I found it during my time as an engineering student. It's been inspiring watching you never give up and always trying to find ways to improve.

hell yeah!! after all this time! great work! never give up!!

Sehr gut gemacht.

Looks good boys! But you need kerosene or jet a1 fuel to get it to work properly! Your design is excellent, but it needs kerosene to work! Start with propane maybe but then switch ro kerosene! It Will start on kerosene alone but easier with gas. Maybe use pure propane instead also, butane is not that good. But, good job!!! So nice to see!

Well done, so nice to see!! But you need to inject kerosene or a1 jet fuel! Then you get proper power!

At last... Well done!

Geil sie läuft 🎉

The Madmen, they actually did it. Well done!

Well done! Definitely self-sustaining. Now you know how much fuel these things need, even to start up. My impression is that the flame is a little unstable, but very well done.

RIP tweeters! well done great run! So awesome!

Bravo!

the engine needs pressure, try to slow down the air more by closing the holes in the exhaust diffuser that is discharging the air over the combustion chamber. slowing down the air by closing the exhaust hole the pressure will increase.

Berner not werking bro

Sounds like the RPM was dropping slowly everytime you removed the motor - I say no self-sustain yet

have you considered using 3D metal printing? chinese unionfab has lower prices than western printers and I have talked them into including inconel 625 (chinese equivalent)

Bro you can heat the propane tank to maximise the output gas pressure

Hello, I noticed your gas setup is using those small propane tanks if you want to move up to the larger tanks, I'd suggest purchasing a propane line, then making or buying a fully brass/copper cored plug for the line. The way I did this was quite simple. I drilled a 2mm hole in the plug, and then threaded it m2.5, M2.5 and M3 have the same Pitch but different diameter, which is good in this case because a steel m3 vented screw when inserted will provide a full seal as it has to press form 0.25mm of the softer material. Once the screw is in the plug you can couple it to your jet engine with a threaded pipe or long Nut.

i hope you read to me, you need to increase gas pressure, you can heat the gas tank and reduce the gas line and the head help the butane to evaporate more fast (when you heat the butane comes out very cold).. take carefully bro..

Very nice and clean assembly, congratulations. However, I don't understand your choice not to make the diffuser with the inclined blades adjacent to the compressor, which are essential for directing the air flow. I also see the injectors that seem to spray towards the turbine. Instead they should be back flow to burn the fuel more efficiently. You probably also have the internal diameter of the injectors that is too large. It should be 0.8 mm or 0.6. Try making these changes and you will see that the engine will run without problems.

Es ist mir nicht möglich ein Bild unserer Turbine einzufügen

Welchen Treibstoff hast du. Gas betrachte nur als Aufheizung für das System. bei ca 20000 Undrehungen dazugeben von Diesel mit 2%synöl, wegen der Lagerschmierung. Kein anderes Manometer Drehzahlmesser ist wichtiger, welche Selbsterhaltungsdrehzahl habt ihr errechnet ?

Brennkammer solltest du aus 0,5 oder 0,3 er Blech machen und das dann Punktschweissen,das ist viel einfacher und spart Gewicht.Verdichtereinlauf aus Kunststoff haben wir schlechte Erfahrungen gemacht. Staubpartickel verschweissen das Ganze.Schmierung haben wir Diesel mit 2 % syntetiköl, abgezapft von der Brennstoffleitung und vor dem vorderen lager in den Tunnel geleitet (Injektionsnadel). Lager nur vollkugel käfiglos Ceramikkugeln 120000 Umdrehungen halten die anderen nicht lange aus.Das Aussengehäuse haben wir aus einer blauen Gaskartusche gemacht. kzbin.info/www/bejne/qHWvqmucidSjppI&ab_channel=LotharZimmermann

Please install the spark plug😅😅

where can i find the plans for this engine?

Your persistence with the project is admirable. I think the compressor diffusor needs some re-design as it not only needs the vertical guide vanes that you already has, but it is also missing the horizontal guide vanes which radiate out from the edge of the compressor to the edge of the stator, the vane would allow you to compress air effectively by changing the path of the air. Hopefully this can help. Also, try using a larger compressor as this compressor is way too small for a turbine of that size.

this is quite a small compressor for a turbine this size... try a larger one, it might work!

Benötigt man für das Verdichterrad zu fräsen einen 3D Fräser?

Wie kann man Sie kontaktieren? Ich hätte fragen!

können sie bitte die linke schiken von vo sie die taeile gelauft haben bitte

Which battery-powered engine powers the jet engine?؟؟؟؟؟؟؟
