  • Hi,
    after much thinking, I decided to rebuild and upgrade my jet engine.
    The results are not bad so far :-)

    You have done a great job, keeping the EGT that low shows a lot of potential, if you can get another 10k RPM, the thrust is going to be so much greater.
    Looking at something like a KingTech 450N turbine, they recommend a 2200mAh 3S battery for the ECU; it is worth looking at the fuel consumption figures (which I imagine will be very similar to yours) and what pumps they are using.

    Yay, you did it! Still betting on that theoretical 150lbs of thrust. 👍
    Add: I missed it the first time, but I used a tea kettle for an intake house once before due to the pre-cut hole being rather nice. Never thought about using it for a nozzle, but I tend to have sized exhaust runners for a free power turbine on my larger units.

    • @Praendy

      @@Praendy I meant to add this to the previous comment but forgot during musings on tea kettles, but as I'm sure you're aware, jet engines really don't 'wake up' until they're above that magical 90% throttle zone. It's not uncommon for a well-engineered example to almost double its power output going from 92-104% throttle, though it's also right on the ragged edge of temps spiraling out of control. When you said you still have or expect another 10k rpm to play with, that's where there's a mighty lump of power dwelling in that hole. The AB on your current configuration ought to be Real Juicy!

    • @Praendy
      @Praendy  Рік тому +6

      I know, what you mean😁
      So far it was only a hot fart for the engine.
      I guess 150lbs are minimum, but I also want to take care, not to overstress the engine.
      Now its 4 years ago, when i start the build.
      In April 2020 was the first run and now I have some positive results.
      100lbs + afterburner should be ok for some tests and displays😊

      Hey Andy
      Dankeschön 😁
      Bin echt gespannt, wie sich dein Nachbrenner mit dem neuen Setup macht😁👍
      Hab letztes Jahr im Juni mit dem Bike angefangen und mich in dem Zug leider auf einen viel zu kleinen turbolader fest gelegt.
      Sollte günstig sein und eine gute Ersatzteilversorgung haben. (Komplette neue Rumpfgruppe mit Wuchtdiagramm ca. ca.50-70€😁)
      Da wurde es dann ein Garrett gt2052v mit 38,5/52 verdichter.
      Der turbo ist mittlerweile aber absolut an seiner Leistungsgrenze.
      Hab bei 2,1 bar ca. 6kg schub😂
      Gerade so Fahrbar macht's dann erst der Nachbrenner.😅
      Mehr Druck traue ich mich nicht, der fliegt echt fast aus einander.😅
      Hab jetzt aber noch eine Rumpfgruppe fertig gemacht mit einem gefrästen 38,5/55,2 Verdichter.
      Die Rumpfgruppe wartet jetzt aber noch auf ihren Einbau.
      Wirklich viel mehr Leistung wird da bestimmt nicht kommen.
      Baue deswegen noch eine zweite Brennkammer für einen gt3582 Nachbaulader mit 61,5/81,5 Verdichter.
      Hab als Ziel ca.30kg Schub raus zu kitzeln.
      Mal schauen, ob's klappt.😅
