Homemade Jet Engine 3.0 | construction phase 1
Homemade Jet Engine 3.0 | construction phase 1


So, here we got the Sketch oft the new Turbine. We will start with showing you the most interesting changes we made: The Case is in diameter much bigger now. This results of the changes we made on the Combustion chamber, which is designed bigger now. Although we led most oft the shaft mount the same, there are also some changes located there. The combustion chamber isnt screwed with the Diffuser anymore, it lays behind on the bearing seat. As a consequence the sprit supply doesnt run through the diffusor (we made here a diffusor with wedge vanes). What is missing in this sketch ist he oil suppliement. The bearings that we got now, have to be sprayed constantly with a kerosene/oil film, which isnt mentioned in this sketch yet. We will lay tubes there similar to that, which will lead tot he outside through Diffusor blades. Turbine blade and stator are the same as in the old model. We didnt had to create new ones, and we are happy oft hat, because its a lot of work. The shaft is thicker now, which makes it more safe. Now something to the combustion chamber and the spray feed. The sprit will not be sprayed through simple tubes anymore, but redirected with this hook tube and also coverd to another rube. This leads to more turbulence and intermixing in the combustion chamber and as a result oft hat to a better combustion. For now, we will take a short look at the diffusor, we got a sketch here for demonstration. As we said, this is a frontale profile of this part here. And as we mentioned you can see the wedge-shaped blades arranged in this room. It was pretty difficult to find out the right angles for that and we are still not sure if they are 100 percent correctly. We got some comparative values from other turbines, so we think should be fine. Beyond that, the gap between difusor and the housing is smaller now, because it probably was to big in the earlier version. Okay, this is ist he compressor blade. It is milled from a whole piece. Coming tot he case: This one here is a stainless steel pipe, which we processed with lathe from inside and outside. Ist not in ist final version, because we are using a wood part there so it can be spinned at lathe.
This leads us to our next big part, the diffusor. As we already said, these are the blades and here are the vanes. The compressor will be built in here and will then do its work. All in all, this looks way better than the old turbine. In the end, it all will look very similiar tot hat, of course inculding a cover, axis and so on. But these are the parts that we got for now. We know, they are not so many, but you have to consider thats incredibly much work. Just take the difusor: We had to
process it on lathe everything, it is milled from a whole piece. Then we milled the blades and had to mill out the slots fort he vanes. In a next step we had to bend sheet and stick it in here. Then we put it into lathe again and bring it to the right diameter Here in this bearing seat we install the ball-bearing again, they also have the same size as earlier. Still 608. Here we got the ball-bearings which we’ll use. These are special ball-bearings for up to 120.000 RPM or higher. They include ceramic balls in ceramic cage. So, yes, these are are the parts that have for now. Ist not the whole turbine yet, but ist a start. Stay tuned and keep watching.

    very nice, keep it going

  2. LordDecapo says:

    so can't wait to see this thing built. Your last one is one of the reasons I'm designing my own turbine currently xD

  3. El Tacco Grande says:

    Sau Geiles Projekt, Bin ja seit Anfang an dabei und freue mich jedes mal wenn ein Neues Video draußen ist.

    Lg

  4. M K says:

    Great work 🙂
    Can you link datasheet for bearings you're using?

  5. Luis Maximilian says:

    Bei dem entwurf ist die mittlere linier niecht eine symetrie linie?

  6. KlixTrio says:

    Finally no more tin cans! Haha, hope this new design works!

  7. Jason Mills says:

    12,000 revolutions is probably significantly under the value required, you probably need in excess of 25,000 revolutions to see a significant pressure ratio across the compress section. Check out "Gas Turbine Engines for Model Aircraft" by Kurt Schreckling, it can help you calculate the revolutions needed for a given pressure ratio. The reason you didn't reach high revs before was probably due to vibrations. Balance your engine, at least with the single plane influence coefficient method. Good luck, you guys are inspiring!!

    I very much appreciate the subtitles and I've been following your project since I found it. Keep up the good work

  9. TurbineBoli says:

    Das schaut doch schonmal viel besser aus. Eine kleinigkeit, lasst die dünnen röhrchen für den Sprit bis nach fast zum anfang der Sticks laufen und dann nicht komplett umbiegen sondern um die 90°. Stellt euch das wie nen vergaser vor, wo Spritt mit Luft vermischt wird. in der Zeichnung wird einfach nur nen Strahl in die Kammer fliegen.

    Thanks for sharing with us… great job!

  11. ZZ Cat says:

    Very nice work. Are you able to get the turbine to self-sustain yet?

  12. MrBen527 says:

    Looking good man!!

  13. Сергій Свириденко says:

    У Вас талант! Успіхів вам! (ukrainische Sprache)

    When You make axial jet engine&

  15. Atom Studios says:

    was benutzt ihr als trtreibstoff?

  16. Camilo Idarraga says:

    Increíble trabajo, gracias

  17. majestuosof says:

    Hola estoy interesado en un shaft y un axle como agosto para comprarlo con ustedes

  18. PracticalProjects says:

    Now that looks more like it, keep up the good work! Looks a promising design this time 🙂

  19. George H says:

    Very Nice Video ..Incredible Work .Please tell me the model of ur Milling machine ?

    Nice Video bro, but why am I writiting english? Ich bleib dran, wer weiß, vllt. werde ich auch einmal die Feuerwehr rufen müssen, weil meine Werkstatt angefangen hat zu brennen…. Warum auch immer… Vielleicht weil die Engine zu heiß wurde oder so…. Ich halte ein Auge auf das Projekt

  22. Tre'von Cowen says:

    why did you all go with a cyntrifugal flow design

  23. HackfleischHeidi says:

    einfach geil!

  24. Sam King says:

    Sind die Lager gar nicht vorgespannt?

  25. Leonardo Nascimento says:

    hello friend you sell this turbine

  26. Vlad Ilisan says:

    Hi!Great work!Can you make a list of parts we need?

  27. farrukh abbas says:

    Test video?? I hope this time it sustains 🙂

  28. Anthony Paull says:

    Have you tried lightening some of the components by hollowing them out? A lot of compressors are hollow so they can put more of their energy towards compressing the air.

  29. Caroline Cupboard Alan says:

    I need your plans.thanks

  30. wop top says:

    warum nehmt ihr keinen axialverdichter?

  31. boris said says:

    Werner Von Braun would be proud

  32. boris said says:

    Do you have the plans

  33. Shoaib Pasha says:

    can I get dimension of dis jet engine

  34. 宇冬马 says:

    I like your video verry much.My dream is also to make a turbojet engine.Can you send me an electronic version of the turbojet diagram?My mail [email protected] THANK very much

  35. der_luemmler says:

    Kannst du mir die abmessungen geben? wäre echt nett 🙂

  36. Juma Mustapha says:

    so good
