Thanks, I wanted to start simple, but I absolutely need to do a multi-stage axial... No doubt. It's tough, this one has been 4 years in the making simply because I had to develop the material that I'm using here to make it possible, I also use that same material for all of my other see-through engines, but I haven't patented it because as you may know I need to release the recipe in that case, and the market is very small for this only for educational use. But then if it's publicly used and it fails for instance in a school or something like that, I could have a big problem on my hand. 😬

It may be small, but if something went wrong, you definitely wouldn’t want to be standing right next to it.

He can probably sell this as a training video $$$

To be fair, this isn't half as complicated as a commercial turbo jet engine and is at best able to show the most basic concept of function of this equivalent. But i agree that it's quite interesing to see the workings in this little thing.

You should probably find some better training classes then, because no matter how cool this is (which it is) it doesn’t really tell you much at all about the working of a jet engine.

​@@WarpedPerception 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.

@@WarpedPerception Everybody loves P&W. "In Thrust We Trust". ( Except maybe GE! ) LoL!

question when the jet engine starts what keeps the blades spinning? is it spinning because of the vaccum of air coming in caused by air being pushed out of the back? i understand how the electric starter compresses air enough for the fuel air ratio to be right but my imagination is limited to my knowledge of car engines

@@mikerodix4800the turbine and compressor wheels are joined via a common shaft. if one spins then then the other will spin too.

Fun fact: I interviewed with P&W in Mass for a ceramic coating robotic programming job a few years ago. I aced the interview but turned the job down as it didn't pay enough and finding a place to live in that area was difficult.

theres no bypass though? this is a turbojet, not a turbofan

@@swagfish1996: not all of the air in a turbojet engine goes directly into the combustion chamber, some of it bypasses the primary stage and is introduced downstream to cool the engine and provide additional air for complete combustion. I think that's what the commenter above you was noticing. With that said, it's definitely not bypass air in the same sense as a turbofan engine, because it's all still going into a later part of the combustion chamber. But I suppose it could be seen as bypass air from a certain point of view. One thing I will say is that supersonic turbojets have bypass ducts because that's where the excess airflow from the intake goes at supersonic speeds... but none of that flow enters the engine core.

@@ErickCTo clarify; In a turbojet, air that bypasses the combustion chamber rejoins that flow before the turbine. This serves to moderate the temperature of the gas hitting the turbine so the turbine doesn’t overheat and fail. This is called “internal bypass”. Turbofans do this as well, but the difference with a turbofan is that they also have EXTERNAL bypass air. Most of the air coming off the fan bypasses the engine core completely and is only used for thrust.

Thank you all for the clarification on internal vs. external air. I didn't know the difference other than the air missed the combustion chamber.

Follow Jesus and you will not be ashamed.

@@Macattack7 Hey Tony, Thanks for the question. My degree is non-technical which means I can't claim to be a scientist or engineer sadly. But during my undergrad work I still had to design a mathematical model of a jet engine, I used excel. Matlab wasn't a thing back then. Also had to get real familiar with things like GPS and GloNASS, aerodynamics, orbital equations etc. I am a pilot with with 2 certifications, private and unmanned. My grad degree was less technical. The first half of it focusing on airline operations, second half focusing on space exploration. As my thesis I researched and wrote a paper on ethical governance of space based resources and off planet colonies. Really it was just an excuse to research how a Mars colony would be governed. Work wise, its all been aviation. Started my career at a flight school, moved on to a high altitude research center where I conducted cabin pressure research for boeing to see if lowering the cabin altitude made for better pilots. A short stint in operations or KTUL, then on to aviation operations for a part 135 operator. Currently i teach drone law. Built and flown two aircraft, one of which was experimental (the better of the two I might add, lol). Been around jet engines my whole career, even got to fly a B-17 (not jet obviously) for a summer during airshow season, and at one stop flew it with Buzz Aldrin!!! A lot more experiences in the last 20+ years but those are the highlights. Sorry for the long reply, but thats what it means. Still mostly interested in space though.

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.

If my knowledge serves me correctly. The type of engine is a centrifugal engine. I struggle trying to remeber the type that are common on todays engines.

I just don't remember what the technical name for that type of engine is?

@@christophermcmichael880 Turbojet? Just the turbofan without the bypass.

@@IJsbeer74 Thank you Agent JayZ.. the other most common type of turbo jet engine compressor is called an Axial flow compressor which has the different stages from low compression to to high compression befoe entering the combustion case and liner.
