An electrician that you will adore with a jet engine is it an engine. Electrician????? An engine that is not electric, any non-quality engine, for example, that runs on gasoline, for example, can you clarify from your honorable person, if you would be so kind ==== How fast is the electric motor in your engine model. This is how many revolutions to achieve the required speed for the jet engine to rotate at a high speed and to generate a very large force so that any aircraft can take off. Thank you

      @Adrian insight about the ratio heat expanding the gas adds to propulsion versus potentionial turbine speed if driven by motor would help illustrators but combining liquid nitrogen with the turbine that uses superconductor motor and ambient heat drawn in from atmosphere requires entirely new design.... for the nitrogen to be heated above freezing point of water requires immense amounts of air being cooled NOT heated. But it is that cooled air ejected at high speed that the nitrogen boiling can 'push' with turbine being an accelerator only slightly and as minimally as possible warming the nitrogen gas.
      Such a plane would of course have to be huge and surface effect only suspended. But it could go very very fast emissionless and carry immense tonnage beyond the nitrogen- and that nitrogen has more energy then lithium batteries in this application although less then hydrogen but when hydrogen is burned in a turbine it is very unclear how much energy is loss versus using it to generate electricity chemically for torque.
      VERY VERY LITTLE DISCUSSED but the future of aviation rests on it being similar or the future is compromised as to proper plan
      I know what I don't know and have identified that so somobody can end that.
      Altitude is not important for long distance 'flight'
      it's getting cargo out of water away from whales that matters
      adn speeding it up with 'yanking' adding to system tremendously for maintaing speeds almost entirely...
      THe nitrogen turbine helps yank when passing other just above wave tops of ocean hypersonic craft via old school floating cables.... however suspended they be.
      jets are insane to depend on even more so then propellers
      we use geothermal energy to snap nitrogen into lighter denser material then increease it's mass as we accelerate turning it back into vapor
      phasechange dependent turbines like water are better then co2 single phase because stationary powerplants
      castrate our efforts to clean up our planet
      liquid nitrogen is the new steam- yanked hypersonics the new locomotive

      ​@Warped Perception liquid nitrogen is worth using as the 'combustible' as it does not cost much and myths about it not be energy rich enough persist.. but instead of fire generating heat you have to drastically disperse perhaps with room temp thermal superconducting materials or some sort fo nano structural vapor skin...
      when air is sucked in at great volumes it does get hot but can it provide enough heat to boil the nitrogen comparable to the work of compressing the air? I know it can be done because the extreme pressures the phase change generates make burning fuels incomparable. The challenge however is not overcooling air as I noted in other comment. It will condense water of course and that water is a good eject if sent out fast enough but creates inelasticity of course even expanding if toomuch mass is shed (any crystals formed transferring mass to heat of course right?)
      Or can you by agitating the water vapor sufficiently maintain it's mass despite it being cyrogenically cool? I doubt that!!! If you managed to do that the exhaust gasses would be icy literally and provide a ground effect maximising sought turbulence at backside of jet snow forming and those crystals being like parachutes to push off of a real brain riddle right!
      they would constrain atmosphere for sure! Exhaust gas crystals only happen when you boil not burn your 'fuel'
      a fuel our atmospher is mainly just preboiled like lithium batteries right?
      capable of being reboilable
      not just good enough for lettuce bags to turbo profits by displacing oxygen
      oxygen is not needed for jet engenies nor is water vapor a threat
      nothing boils nitorgen better then warm rain
      snow of course in freezing air would need a filter that prvents it from getting into nitrogen boiler parts of turbine however snow compressed does melt forming eject that again snows
      all this molten not just nitrogen around us but practically plasma already and we care about our bodies when judging it's value
      it's energy
      so hot!!!
      so capable of releasing potential energy of snapped nitrogen molecules by increasing there mass!!!
      Boiled nitrogen is heavy and superheated by sun it has plenty of bonus heat to increase i wonder what the ratio of nitrogen snapped at 40 degrees or say 5 degrees celsius free nitrogen is... how many grams of liquid can be melted by how many grams of free to mine air???
      i feel so ignorant not knowing precisely and lacking the equations on my watch
      ocean surface howvering hypersonics have hot humidity always to work with
      so far less volume versus dry air is needed to boil and spin the turbine
      if spinning is even right the densnapping process we must have open minds for
      again the free molecule is heavier not lighter
      ice is lighter then liquid water not just by volume
      but atom duh
      it is nuclear energy that is released when atmoshpher nitrogen vapors shed heat into liquid nitrogen this nano process of seperativing the N's far enough do all the work we need done if only, if only the immense power of those forces can be harnessed.
      When heat turns into mass WATCH OUT
      this other side of nuclear is our greatest nastilly kept secret
      steampower was replaced by octane nonsense talk
      always corrupting is the song of jet fuel
      burning petroleum is to sell it duh
      with almost none of us owning any
      no a planet rich with heavy nitrogen for free omfg?
      or you got no courage?
      are afraid of texas or going kashogi?

    3:10 The exhaust nozzle looks like a convergent nozzle but it is actually a divergent nozzle. Inside of it the area where exhaust gases exit the turbine blades is small and it gets larger as it exits the nozzle assembly made up of the exhaust cone and exhaust fairing. Some exhausts add to this effect with an internal Pen Nib Fairing Assy. which is wide at the front and tapers to nothing going aft. I think they do it that way to cool and quiet the exhaust gasses on airliners. If I'm not mistaken, on military fighters they design it to speed up the exhaust gases for obvious reasons.....speed.

    It would be awesome the possibility to see through the combustion chamber. Maybe you can change half of it for glass (that should not melt if you run it not too fast)!
    Ps: I guess that for giving away half of the combustion chamber you would need also change the air flux (blocking part of it os something?). Since the relation air flow vs. fuel flow maybe is nonlinear, some fine adjustments regarding this would be necessary.
    Hope it works fine 🤞

    You've actually made a truly priceless illustration of the jet engine's dangers by pulvering some mist at it.
    It can be seen in slow motion that not only the air was pulled in from infront of the ingine, but from behind as well.
    This is a neat demonstration of the Bernoullis principle, which states that increase of a fluid/gas speed will also decrease the pressure in it, and wise versa. Therefore, things may not only be sucked into the inlet from sides, but into exhaust too, in which case they will be immediately burned and blown away at a drastical speed.
    Take care around your engines, and have a nice day.

    I work on jet engines a lot and your video is going to be an amazing way to explain the system. Basically, jet engine theory is that the flame NEVER actually touches the combuster case. It is actually “floating” on a constant stream of air fro those inlet ducts and holes to control the flame and keep it centered to provide the optimal burn and air/fuel ratio. That’s why you see the flame get more and more focused and concentrated as it spools up.

      @Mike Rodix The blade at the back is fixed to the same shaft that's attached to the blade at the front. When the exhaust is pushed out the back, it goes through that blade, which forces it to spin, and consequently forces the shaft it's attached to and front blade to spin as well - which sucks in more air, which mixes with more fuel and repeats the process.

    8:45 Perhaps true for a low bypass, or no-bypas engine like this one, but not the case for high bypass, where typically around 80% of the thrust just comes from the massive amount of air being moved by the fan, and bypass ratios of around 10:1

    Thanks so much for this. My father designed jet turbines for General Electric from 1952 to 1990. He started when jet engines were primitive, prior to the high bypass turbofan, and retired at point when the technology had matured. In 1952 it was not uncommon for jet engines to--how do I put this delicately--explode. He has dozens of patents in his name, and is one of the relative few to be inducted into the GE Aviation Hall of Fame. One of his major projects was the TF-34, which powered military and civilian aircraft, but is probably best known as the powerplant for the A-10 Warthog. He is still with us, and I am going to show him your model. He'll get a kick out of it!

    5:14...Great little jet motor, and great video, with a couple caveats. One of the four screws you used to hold it down seemed to be coming loose. This reminds me of the time two years ago when I tested the motor of a trash picked vacuum I found in pieces to see if it worked. I was stupid enough to not mount the motor in the vacuum first, believing that I could hold it down. It got loose like a bucking bronco! Fortunately, the GFCI kicked in and tripped the circuit breaker. So the damage was minimized. But had your see thru jet motor gotten loose, it might have gone flying all around your shop like a balloon with all the air let out, possibly injuring you and starting a fire. What surprises me is that a mere FOUR screws was able to hold it down during your demo!
    Later in the video, you said you were surprised it did not blow up. WOWSERS! On the one hand, kudos to you for your precise engineering! On the other hand, you probably would have been hit with red hot shrapnel had it blown up. If it were me, I'd do that experiment in the middle of nowhere, with remotely controlled cameras set up to record it, while sitting in a foxhole plenty far away. And I'd be sure to yell "FIRE IN THE HOLE!" if anyone else is around. On the one foot, how could an engineer such as you overlook these precautions? On the other foot, am I missing something here?

    Nice job!! Built two jet engine models my self so be be careful with this glass cowling. Use locktite on all screws cause of hi freq vibrations, tends to loose screws very often and easy. These axial movement that you had with engine could cause NGV to make contact with turbine wheel....which is bad at RPM higher than 100K. Usually there is a gap approx 0.8-1 mm between NGV and turbine blades because of thermal expansion of whole engine(shaft tunnel) so be careful with that. At 100k RPM and more, any issue can be a cluster fuck up :) ....God job!

      That was one of the two interesting things that I noticed. It makes sense because the intake end of the combustion chamber is cooled by the incoming air, so temperature increases in the flow direction as combustion adds heat.
      The other interesting thing was the thermal expansion which the builder noted in the video.

    to avoid blowing up of the gasket You can use long screws to pull the both flanges in place.

      It seems like there needs to be gearing between work harvesting blades and those that impart additional velocity to denser exhaust reducing it's pressure presumably once release if at fast enough speed for remaining distance....
      the engine provides thrust by making air around and outside engine move so the smoke test demonstated that to me mainly despite engine being stationary no spoke that gets past it's entrance can be suicked into it. If it was braking it could suck all the smoke more easally

    • unmountable boot volume
      unmountable boot volume Bulan Yang lalu

      @melonbobful I would say they definitely experience a whole lot less stress when in continuos operation, as they see almost no thermal cycling, and the hydrodynamic bearings rarely come to a stop, which greatly extends their lifespan, as they run on a film of oil when turning, making them last infinitely long and suffer no wear at all once running (except for a potential thrust washer, but that's not a part of the bearing itself), but during startup, there is no oil film, meaning they will have metal-to-metal contact until a film of oil has been established. When a gas turbine is running, the only wear it experiences is dust particles from the intake air hitting the compressor blades, but when it is stopping and starting, bearings run dry and thermal expansion causes metals to fracture. The same is true for the blower motors on many wall-mount condensing boilers, which are also meant to only start up a few times per month or even per year, and then keep modulating, possibly for weeks or even months on end, which means the bearings (that often are hydrodynamic) will also keep running on an oil/grease film minimizing wear. That is also how these boilers last 30+ years, while many similar fans in other applications fail after only a couple years. That is also the reason why these boilers will quickly fail if they are oversized, as they have to constantly shut off on overtemp due to their minimum modulating power being far greater than what is needed at the moment, and restart shortly after cooling down, which they simply weren't meant to do, causing many parts like the fan bearings, spark electrodes and gas valve to wear out quickly.

    Very cool and fun to watch! My two cents: the thermal expansion of the aluminum frame (the longitudinal pieces on top and on the bottom) is much higher than the glass case. So, as it heated it wanted to grown longer, and the glass did not nearly as much. That's why I think it separated somewhat pulling one of the gaskets with it. Probably some of the other 2500+ comments said the same. My fear was the glass shattering! Now, even if it did not this time, with multiple cycles on it, it still may so please continue to take all safety precautions with this engine.

    • Håkon Fløystad
      Håkon Fløystad 2 bulan yang lalu +1

      Pretty sure the expansion is not thermal, but almost completely caused by overpressure inside the engine. You can tell by how the engine instantly expands when fuel is burned (which increases the internal pressure).

      There's no way that's any kind of glass. Unless it's laminate borosilicate. Glass likes to explode into lethal debris. With something like this, you want your failure mode to be phase transition, not rapid lattice decomposition.
