See Thru Jet Engine
ฝัง
- เผยแพร่เมื่อ 23 เม.ย. 2024
- I put together a small Jet Engine with a See Thru transparent housing to allow us to see inside of the jet engine while it's running, I explain the combustion process of the jet engine from the compressor to the turbine wheel and show visually how the see-thru Jet Engine Works.
I then film it in slow motion with the high-speed camera to get a better look at how the jet engine works but it wasn't such a big difference.
The amount of heat generated inside of the engine only a few millimeters from the outside cover was pretty impressive.
At the end I did inject fog into the intake of the jet engine to try and visualize the airflow into the engine and how the engine is ingesting air.

I've worked on aircraft and turbine engines for 30 years, and never thought I would see what one looks like on the inside running. Even just a basic one like yours is pretty neat.
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. 😬

Welcome to the 21st century, where geniuses casually put together jet turbines in their garage using the most amazing private tool array and broadcasting all of it for the world to see. What a time to be alive!
8 years ago Colin Furze made a working jet engine out of an old turbo, a loo roll holder, a toilet brush and some duct tape. I know it sounds like I'm quoting ironman but it actually happened and to this day it's still one of the best videos on TH-cam.

An unfathomable amount of respect good sir, very interesting and well explained video to, all the questions i had you answered throughout the vid!
Thanks, I tried to cover everything.
That hit almost 130k RPM. That's incredible, and I'm surprised it stayed together through the testing.
it blows my mind everytime im reminded of how fast turbines spin, even in regular cars, their turbos can spin anywhere from 100 to 140k rpm

dude i was thinking the same thing!!
I’ve been designing jet engines professionally for 32 years. Never seen inside one when it’s running. AWESOME!!
❤️ as a fellow engineer, that's amazing to hear... Thanks!
If you ve never seen how it works inside how did you even design them ?
@@genekisayan6564 🤓 Your question is basically the definition of engineering. Design, analyze, build, test, repeat.
@@genekisayan6564 Scientists create theories, engineers bring them to life. You need to use your imagination! Mechanical engineering is more art than science, yet still needs to follow strict rules of logic. Otto created internal combustion engine without seeing through its walls, and so did Diesel with his engine.
@@lukem3250 pretty reductionist, mechanical engineering is 100% science. We've been building internal combustion engines for over 150 years.
"I'm glad it didn't blow apart." I got a pretty good chuckle there. As I was watching the thing spool up to over 100k I was thinking "this guy's five feet away from something that could end it all in less than a blink of an eye if it all went to poo". I respect somebody who's got that kind of confidence in their own abilities and can demonstrate it for our benefit. Well done.
When I noticed he was several feet away from the engine, I thought it was a bit of overkill… until I realized this wasn’t a toy engine (unlike another video I watched yesterday showing assembly of a Japanese turbofan engine kit made from metal parts). 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.
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.
I'm a 20 year Airline Captain.... every training class I've ever attended in my career falls well short of what this video teaches. to view the actually work inside is mind blowing. thank you for dedicating your time and resources to reach other. God Bless...
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.
@@cattnipp you really want to be the butt
As a recently retired engineer in the aerospace industry, I fully agree. To see the thermal performance of the combustion chamber was astonishing.
I flew jet airliners for over 12,000 hours since 1984 and of course never got to see a burner can in operation. Very nice craftsmanship building it. Thank you for a very informative video!
Thanks! I'm hoping to show more.
@@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! FIGHT

Just curious; you say you’re an aviation professional with a masters in aviation and space sciences.. what does that mean? Are you a mechanical engineer? Aerospace engineer? What was your title
"masters"..LoL.
@@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. Its just really hard to get into unless you have the engineering title.
@@r0ky_M Master's....Better?
Great job! I worked as an engineer at Pratt & Whitney for 24 years and found this video very interesting.
Thank you... I love Pratt and Whitney
@@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.
As a helicopter pilot there's no sound more pleasing than the startup of a jet turbine. Having watched your video I can now truly grok what is happening in the engine in pre-start, initial ignition, complete ignition, and the spooling up as the cycle completes. Wow, just plain wow!! 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. :)
Seeing inside ANY kind of engine while it runs is a dream come true!
I'm a recently retired middle-school Science teacher. I've "known" how jet engines work for years...as much as one can "know " something from looking at drawings and photos. To be able to see the inside while it is in operation was just incredible. Thanks for making and sharing this vid. I wish I'd have had it while I was still teaching.
The issue is are you now ready to judge the Toshiba illustration video of using superconductor electric motor to spin turbine lol?
Jet's run on air not petroleum
You are still teaching, please have no doubt about. A good teacher gets better whole his "local" life and beyond. You do remember your own tutors. I bet you did not stop learning from them even for now, and they will continue teaching your students along with you. It's not "a man gets smarter" it's Socrates and Archimedes have been in the class all this time. "I am a clever man on my own" - what a greate phrase for a comedyan:-)
As an A&P up and coming mechanic, this fascinates me to bits. Thanks for the video and see-thru characteristics.
I love how one of the biggest technological advancements of the 20th century is now just a thing that people can build in their garage.
Ha! I think not.... This is no ordinary guy and that definitely isn't your ordinary garage... He's more than likely an engineer for NASA, or Boeing, or something of that magnitude....

@@joeyditcharo419 I would like to introduce you to integza who literally 3d prints jet engines, if you have the right 3d printer then you can download his plans and print one yourself. I believe they require other components but a normal person could easily make one themselves with machines and parts that a normal person could easily get.
@@joeyditcharo419 You don't need to be an engineer at NASA or Boeing in that matter. You wouldn't build an entire engine there anyway but a specific dedicated part or something.

As an aviation expert, NASA engineer, who has worked 200 years on the top secret SR-78 Aurora from the future and returned back in time just to write this comment, I must say that this is quite impressive to see in action.
Hahahahaha lmao
If thats true, run! Now NSA is hunting your ass
The parts about the "200 years" and the "SR-78" seem legit. I can't prove those facts wrong.
However, there is no such thing as a Nasa engineer. It's NASA (regardless of what you might have read in some goofy British writer's style guide).

Brilliant engineering and design work. I am a retired aerospace/electronic engineer mainly working with communications satellites at TRW, and can appreciate the demonstrated professionalism involved. Too bad I don't have YOUR tools for design work! CAD/CAM wasn't even thought of when I was in college. It was all done by pencil and pen on drafting tables. Kudos to you!
Retired from Pratt and Whitney as a mechanic building the F100 after 23 years only to relocate and now do the same for GE's F110 and wanted to say thanks for the video! I've seen these engines at test cell but it's so cool to see one like this with a clear cover to actually see it in action. VERY IMPRESSIVE.

The fact you say the word “coolest” is an odd choice of word for a propulsion engineer. As someone in my 50s with many years experience in technology, petroleum and the like, I would certainly not use such a young persons trendy word.

@@ronz101 - no idea. Perspex?
@@ronz101 plastic

"Wheeww THAT'S HOT!" was a Eureka moment wasn't it?! When I flew in the Navy we didn't shut down our turbo shaft engines immediately but let them operate at ground idle for a short while for a brief cool down. This prevented the turbine blades from acquiring negative characteristics from a quick cooling off. Consider doing this on your small engine.
Yep you are absolutely correct, the only reason I shut it down to briefly like that was to finish off the scene, normally I let them cool down first for the exact reason you said. Thanks!
When I had a twin turbo Z years ago I would let it idle for a few minutes after a hard run to keep the oil from cooking inside the turbos.
5:49 this is why I'm always amazed at how jet engines are constructed and mounted. The immense pressure they create on themselves while being bolted to, and pushing, a 160 metric ton thing from standstill on the ground to airborne.
Not only just pushing it but also pushing it past the speed of sound!
That's the power of Dinosaur remains
ive been trying to visualize the inside of a jet for decades thank you sooo much! I can finally "see" it.
This video makes TH-cam cruising a top notch educational experience. Thanks!!
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!
Wow dude, one the coolest aircraft of all time 😁😁
Please update us on his reaction to this.
Great story! He will probably never know his full contribution to this world, but obviously it was quite significant.

Born and raised in Tucson, AZ many days and nights hearing seeing the majestic A-10 Warthog flying over the city to Davis Monthan. I love the flying tank. Thanks to your father and many more for such a fantastic piece of Aviation.
It's a wonder you never ventured into his career field
This really helps contextualize the varied sounds coming from jets on takeoff.
Great video.
From 4:20 to 4:40, I was totally squinting and turning my head slightly, worrying it was gona explode. LOL. The pitch just kept getting higher!
You didn't know which sounds were the engine earlier?
@rickyanthony The engine isn't what you hear, it's the thrusters. And I said this video helps contextualize the various, separate sounds within the overall sound produced by the jet.
I knew the fog would atomize in the engine and we wouldn't see it, it's the same with jet engines in clouds or rain. However I'd never have guessed that the plexiglass or glass see-through casing would not melt. I thought this would be on of those "fail" videos where the thing comes flying apart when the plexiglass melts. Great job on this.
I thought about that myself. It probably wouldn’t last in “real” usage, but it seems sturdy enough for a couple or so demonstration runs.
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.
I have been a pilot for 20 years, 16 of those flying jets. This is hands down the best visual aid I have ever seen!

Yes I will do that

That is absolutely insane! I just love how the hot-spots move towards the exhaust side as it ramps up.
Thanks for this amazing and unique content
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.
Never in a million years would I have thought that you could sustain full power on a jet engine for any length of time at all with a transparent housing... but you pulled it off. That has to be a first and probably only. The entire process from the balancing and machining of new parts to the assembly and of course the bench test payoff, all of it was so interesting! So cool to see the inside of an actual jet turbine while it's running at full tilt! Gotta keep coming back to this channel. Thanks for making some really cool science content!
Thank you, likewise, that material took me like three and a half years to develop and I first use it for the see through rotary a couple years ago and then the liquid piston rotary more recent, and now for this, it was a pain in the butt to find a factory with the machine to make my material in this shape. But damn I did not think it was going to hold a Full throttle run, I thought it was going to blow for sure. Thanks for watching, for sure I'm going to have some more stuff coming up real soon. Thanks
Man I love technical ppl like you, you're damn excellent :)
I want a workroom like you have, its like a playground for adults❤ brilliant video and experiment too👍 thanks
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
I worked on repairing the turbofans and many other parts for jet engines from 1991-1995 but never had the opportunity to see how they work and operate internally like this. I wish I had the skills, tools and ability to make something like this. I would have a LOT of fun with this!
Blessings and thanks for the awesome video!
That was fan-damn-tastic!!! Thank you!! Definitely want to see part 2!
This is really cool, makes you wonder what amount of pressure goes into a real life size model of the jet engine. Thanks for this experiment.
60 bar? For some reason lower than in a piston engine.
This is way out of my league, and that's why it's so fascinating! I didn't even think that someone could build all of this at home...! You blew my mind.
Outstanding. I'm ex-RAF aircraft engineer so personally very at home with the technology here but... what a way to demonstrate a jet to the general public!! Excellent!
In awe of the talent to build this. Thanks for the chuckle when you touched it twice when hot. The only thing we have in common 😅. I’d have done the same. That’s where my engineering talent starts and ends.
Induction from a jet turbine messing with harmonics, that’s some nerdy stuff I love it!
Crazy to think that an airplane engine does that for more than 10 hours on a long flight. What a technology.
Not only that but does it with multiple compressor stages
Even more crazy is that industrial gas turbines do that 24/7 and can run for weeks or even months without maintenance.
@@adamk203 they are also full of sensors and all connected to the internet. So a slight variation is caught long before there is a risk of engine failure. That way they can with confidence run it 24/7
@@morten-punnerud_engelstad forget the durability, that in itself makes it even more crazier to be honest
@@morten-punnerud_engelstad Sure, except that industrial gas turbines ran in continuous duty before the internet existed.
What an amazing accomplishment! I've been an automotive technician for 30 years and never dove into understanding jet engines because I couldn't see what was going on inside of them. Thanks for such an amazing video!
4:17 love to see in real time the cone at the end slowly expanding and changing shape due to the heat! cool vid!
5:36 what a legend for touching that plate after running that jet engine
Ive been a mechanic on spacecraft for my system going on 300 yrs, ive never seen such a clear showcase of the engine. bravo!
Where are you from that had turbine engines for over 300 years? Are you an alien? Those tic-tac UFO's that the Navy spotted was your doing, wasn't it. Confess!
@@VolsPride yall are getting close and ill leave it at that.
Yo Matt! Yet another great showcase of both the complexity and simplicity of a jet engine. Thank you for always looking for creative ways to teach amazing mechanical things my man!
Thanks and your welcome, this one was 4 years in the making for various complex reasons but mostly because it took me a very long time to develop the material to use for the cylinder.
I thank that was a quartz tube, isn't it?
@@WarpedPerception 4 years to make a 10 minute video. thank you wp.
@@WarpedPerception I have several of these same jet engines for RC jets and its great to see what goes on inside then. Thanks for the video.
@@gakich. he developed the material himself over the past 4 years, it's his "secret sauce".
Cool video. Loved it all including the drywall screws...lol The perfect fastener even for jet engine mounting.
This is everything. Thank you!
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 👏 👍
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.
To add to the insanity of the units, 3,591 km/h is almost Mach 3! The jet engine is an excellent example of the apex of engineering right after nuclear reactors
How fast is that.. 😳😳😳
Now I get why he was so decided to fix those balancing issues.
How much thrust?
@@TurboMountTV It's over 9000.
Just saw this and I must tell you I admire anyone who can do what you do. It takes a lot to learn all that and just whip up an engine like that. Just learning the various CAD software probably takes years to be proficient. Add 1 more to your subscribers.
That is a beautiful machine. I am fascinated. Now I wanna get together with my retired USAF jet mechanic friend (with 25 years of experience) and buid one. "Purpose?" you say. Did you not watch the video. These things are awesome!
Thank you so much! I was having the hardest difficulties with my physics class, and I didn't understand gas turbines at all. Upon finding out that gas turbines are also jet engines, I watched this video. This gave me a full conceptual understanding of my class, especially at the beginning when you explained the four-stroke cycle in one cylinder. I highly appreciate it, thank you so much I was flunking out of my class but this got me an A!
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.
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.
Lab style protection glasses won't be sufficiently in such case.
Glass pieces are flying bullets then.
UUUUU.....what a FKing horror would it be in such moment to stay 3 meters away with nothing in between.
A TRANSPARENT PROTECTION PANEL LIKE THOSE USED IN LABS TO PROTECT SPECTATORS WHILE DOING CHEMICAL EXPERIMENTS..... LIFE SAVING.
Might be the nxt video to make that glass BREAKING WHILE STAYING REMOTELY IN THE SAFE BUNKER.
PS: DEADLY ACCIDENT HAPPENED WITH FLYING GLASS SHRAPNELS WHEN SOMEONE PUT ONE OF THESE LAVA WAX LAMPS IN A MICROWAVE.
@@ronscrypt2go499 I imagine a few hundred numb nuts who didn't read these comments are probably out there building/testing these engines while wearing only safety goggles for protection😳
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.
@@scottrackley4457 True! His material seems to be a plexiglas or Lexan cylinder. These materials won't shatter, but with enough heat will weaken and reshape. Pretty amazing little demo !!!!
@@McGrumpus Yup. With all that expensive video equipment I'm sure he doesn't want that cylinder to have a SMEF
Wow, that jet explanation was so simple & EZ 2 understand. U're the Tony Stark of jets. Thx 4 sharing on Utube.
Very cool demo. I didn't know you could make a tiny jet engine. I thought they had to be massive. Now I'd like to see one actually in use, propelling a small vehicle or plane. I'll look on youtube.
I was waiting for the see-through hot section case to melt too. I saw the seal on the rear coming out. Cool project. It must be nice to have the laser cutter and the balancing machine. I built jet engines for 42 years. The impeller compressor is old school. I used to build them on the J-69 engine.
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 remeber turbo jet or turbo, shaft and or fan engines. I know that there were two types produced. The Meshersmit 262 had a jet engine similar to this model jet engine. If my memory serves me correctly that is. Most general aviation helicopter engines like the bell jet rangers have the same compressor design.
@@christophermcmichael880 Most commercial jet engines these days are turbofans.
@@-_James_- That I had already knew. The engine that is in the video is a centrifugal compressor engine where it diverts the air towards the outside then into the combustion liner. The most common type today is where the air is goes through the different stages from low compression to high compression then into the combustion chamber and liner. 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. The RC model engine in the video os called a centrifuge flow compessor which only has the single stage. Both are turbo jet engines. The centrifugal compressor is an older design. That engine, the full size version was a German design and was used in the Meshersmit 262. Now the common turbo jet, turbo fan engine as well as some turbo shaft engines are Axisl flow engines.
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.
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.
I love content like this, jet engines have always fascinated me. Excellent Video!
Wow that’s a lot of thrust in a small engine. Thought that glass would shatter from all that heat. 😮
I'm a simple guy who has flown many hours on an airline, in a passenger seat. I often wondered how the engine worked for obvious reasons. Thank you for taking the time to craft the engine and sharing your knowledge.
I've always wondered how a jet engine looks like when it's running and thought of someone to do a transparent one for demonstration. This video is the answer. Thanks, man. God bless!
KC-135R Crew Chief here. We were always told in training. "Suck, Squeeze, Bang, Blow" that's all you really need to remember regarding how these engines work. lol They're not wrong.
13 years working on F-16s and this sounded very familiar. Gr8 work @warpedperception 👏🏾👏🏾👏🏾
I'm an aerospace engineering student about to go into 3rd year and this video has put a huge smile on my face. I have a huge fascination in aerospace propulsion, specifically turbojets and rocket engines so yeah... awesome stuff!
Just turbojets and rockets? Not ramjets and scramjets?
ramjet, scramjet != turbojet
I'm in my third year (aerospace engineering) and feel the same. I've been obsessed with propulsion too. Glad there are lots of people like us out there trying to push the world forward.
@@sciencecompliance235 ramjets are really cool, love the idea of using shockwaves to compress air with no moving parts.
@@blainrinehart8865 Amazing! 😁
Having 3 radio control turbine jets myself, (not ducted fans), this was incredible to finally see inside. It's like magic. I was taught that these were hybrid engines going from radial or centrifugal flow in to axial flow out. Really enjoyed your video!!!
Hands down of the best engineering that I have ever seen, Please put part two together, I would love to see if possible how the fuel ignites inside the chamber, love it! Thank you for putting together all this fantastic material.
The fire part is all for show. Most commercial jets are utilizing “compressed air combustion for OVER 90% of thrust” according to the manufacturers animated video for explanation purposes.
They ignorantly maintain the lie, as 50% of airfares are due to cost of fuel.
@@rickyrabs2582 Seeing that you have a saved flat earther playlist shows us everything we need to know.
But don't listen to me, as a 'highly' trained aircraft fueler I'm in on the lie too!
Unfortunately don't think that's possible due to the heat and pressure inside the combustion chamber. It's a pretty cool process though.
The fuel is sprayed into the engine, initially lit by igniters. Once it's self sustaining, the igniters shut off and the fuel continuously flows into the engine through a mist and keeps itself burning - just like a stovetop burner.
For ATPL exams, it's a game changer ! Thank you !
