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. 😬

Thank you!! As someone has already said, you're a very talented machinist/engineer. As an A&P has said this is accurate and useful. And now you have it from someone who power up, injects air to start the cycle, introduces fuel to start the ignition, and enjoys the resulting power out the other side!! Also seeing the power come from the fuel and not massive amounts of air is a double-take worth its weight in gold. :)

You showed even the engineering and behind the scene stuff which is generally skipped, that is crazy, huge respect!

​@@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. 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? live man!

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

I'm impressed that the bypass air was enough to keep the case from burning. It was also neat to see the jet fuel burning with a blue flame through the openings at the higher power settings. It just goes to show how intense the combustion is.

@@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.

@singleproppilot

@@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.

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!!!

Pretty cool being that I was a jet engine mechanic in the Air Force but also worked in the balance lab as a civil service mechanic where I balanced J85-21 turbines and compressor rotors for the F-5 that the navy used for the top gun program back in the late 90’s out at Edwards AFB. Great video.

Wow- twice I thought "okay, he's at the rev limit now" and then saw the LED display- 6% of throttle!!! Am definitely impressed. Thanks for the vid!

I programmed, and operated an abrasive waterjet for 10 years in a jobshop/Machineshop. It never got old!

Very well done. I love those experiments. One can see the temperature distribution of the combustion chamber at several stages of the run up. Thank you !! One remark from me: dependend on the smoke or fog system you use the compressor heats up the visible parts of the fog so that the vaporize or in case of dry ice sublimate. So the flow after the compressor is hardly to be seen.

Been working with jet engines as a mechanic for 31 years and didnt think id see a see-through version. This is awesome!

0:28 - The rotor's radius is 75.0 mm 8:01 - It reaches a peak of 127,000 RPM Circumference of circle = 2πr = 471.239mm Velocity of blades: 471.239 mm * 127000 rpm = 59,847,340 mm/m The intake blades were spinning at 59.8 km per minute!!! That's 3,591 km (2,231.2 miles) per hour!!! From Los Angeles to Charleston, SC. In one hour.

As a Jet engine mech on F111, F15E, F16, and U2R/S acft that was amazing. The mechanics who have worked teardown and buildup know what happens but in 20 plus years I never got to actually see the flame in a combustor... AB yes... core engine never. I was amazed by the raw numbers... over 90K RPM and over 1000 degrees EGT/TIT... so freaking cool

The most impressive engineering thing I`ve ever seen , Incredibly awesome!

I passed airline interview with your video. Thank you so much.

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.

@ronscrypt2go499

Ohhh definitely, if that glass would one day break...while the jet turbine full in action.... as you said in video the combustion pressure will accelerate the broken glass pieces like shrapnels.....I imagine a horrible deadly accident.

UUUUU.....what a FKing horror would it be in such moment to stay 3 meters away with nothing in between.

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.

Well done! Not only did you show off a beautiful sounding and functioning engine, but you also designed the parts, programmed the Gcode for the CNC, CMM the finished pieces, kept the rings round and flat within tolerance after machining and assembled everything to complete a little jet engine. After all said and done it works! Very good stuff 👏 👍

There have been several comments about the amount of airflow. A manufacturer of similar engines (there are many almost identical engines available) gives specs for their equivalent size (the P130-RX from JetCat): _Name:_ _Value_ Pressure ratio: 3 Mass flow (kg/s): 0,3 Consumption Full load (ml/min): 441 @ 130N Consumption idle (ml/min): 100 Weight [g]: 1326 Dimensions of the diameter (mm): 99 Length (mm): 284 Exhaust gas temperature (°C): 490-720 Idle speed (1/min): 40000 Max rpm (1/min): 127000 Thrust at idle (N): 4 Thrust @ maxRpm (N): 130 Exhaust gas velocity (km/h): 1560 Exhaust gas power output (kW): 28,2 SFC @ maxRpm (kg/Nh): 0,185 441 ml of kerosene is 355 g, and 355 g/minute is 6 g/second. So that's 300 grams of air and only 6 grams of fuel flowing per second, a mass ratio of 50:1. To burn kerosene completely requires 15.6 times as much mass of air as of fuel, so the engine is moving about three times as much air as it needs to burn the fuel; that's excess air, and that's normal for a turbine engine. The thrust results from increasing the momentum of the air; the energy to do that comes from the heat of burning the fuel.

Fantastic to see this perspective - thanks for making this video!

It's so cool to see professionals excited about this. You could know how something works, worked on them, used them for decades...and still blows their minds to see inside it as its operating. Great video!

As a long time mechanic working on four stroke engines I've always had a fascination with military jets and therefore jet engines. It's really cool to see what goes on inside one. I thought that there would more heat and flames going on outside and surrounding the combustion can because I always thought the compressed air went in the front of the can but now I see that the air from the compressor surrounds the the can and that mass of high pressure air surrounding the can forces the air into the combustion chamber from the outside through those holes in the can and also acts to contain the combustion to the interior of the can. Sometimes a visual approach to something conveys wat more then an text explanation or an animation. Great video.

@OverlyCuriousEngineer

Жыл бұрын

That air entering into the can from the outside is known as dilution air and its function is to keep the can from melting. It keeps a layer of air flowing between the flame and the can housing otherwise it would straight away melt within minutes. It blew my mind when i read this. Just the sheer simplicity of this solution.

Wow , the expansion on that thing on replay !!

That was awesome. I got all stressed in front of my screen even though I was safe, I can't imagine how you felt. Still, the pleasure was great.

Whenever I shut down a jet engine, I let the turbine idle for a few minutes to let the TGT drop before shutting it down completely. The manufacturers said it would prolong the engine life and reduce the chance of exploding unburned fuel.
