I'm a 25 year veteran from Duncan Aviation in Lincoln, NE. I can firmly attest that jets work by making a loud noise behind the plane, the plane gets scared, and the plane goes forward. Everything else is a bold faced lie.
Oh damn it , they lied to us !

I trust you
So that's why fighter jets are so loud, they need to be to go fast.
I completely and utterly trust you
This wasn't in your recommended. You actually searched for this. Yeah you!
Look man I needed it for d and d
True
Arrest Tedros Adhanom jokes on you it appeared on my recommended
@@5campos1 Not fair if you've been searching jet engine or physics videos. Ofcourse it's going to appear in your recommended.
Actualy i searched homemade jet engine
I really love the upbeat attitude of the narrator. I bet there's nothing about turbofan and turbojet engines that doesn't fill him with joy.
As a Mechanical Eng. grad but doing business in software, mechanical engineers are most underrated and under paid group of people in the earth. They make the magic and earn a moderate life.
As a pilot in the right seat of a regional 38 seat turbo prop. I earn less then the guys that put the bags on the plane. Not to mention 140k worth of training, loss of income due to training and years of stress and sims every 6 months. We all do highly specialized jobs. The magic comes from teamwork, not individuals.
@@ibsn87 Sir, you by any means are doing a complex and specialised job. Problem here is that you are also so underpaid.
In Europe and Türkiye, my pilot buddies make x10-15 times the lowest salary.
Pls transfer yourself to THY :)
@@semihklcgedik7239 regional turbo prop first officer ~50-60k. Zero qualifications- Dump truck operator working 7 on and 7 off in open cut coal is on 120-160k in Aus. Teacher ~75-95k.
Cabin crew 55-85k. Baggage handler 55-70k. The world is not fair at times. First officer of a 100 seater Jet ~120k. Even that, is less then a dump truck driver at the mines.
As a highschool teacher I also feel underrated; my supreme intelligence knows everything but is treated as shite.
Lol, Civil Engineers are paid the lowest.😂
I love the internet.
I get curious about jet engines and 10 minutes later I roughly know how they work
@@octaneartllc lol
Crazy right.
True but this isn't actuelly a turbojet engine, this is a turbofan engine.

I just want to say WOW. This is some great editing. I bet it took a while to piece together every bit of this information to make this video….. Good job...
Stumbled across this channel and it is now my fav channel on all media platforms. Great explanations on so many amazing engineering devices! Thank you for creating this channel and it’s content.
"the same thing that moves a balloon!"
me: helium?
"newton’s 3rd law of motion!"
What happens when you loosen a filled party balloons air stopper? That's whqt he's talking about.
So can we considered turbine as a auxiliary machine please let me clear.....
Helium doesn't make balloons move. The rapid decompression forces helium out of the small orifice, generating thrust. You'll get the same effect regardless of which gas you air the balloon up with. The balloon skin expands when you air it up, so if there's an opening for gas to escape, the skin will retract and push the gas out.
Lol
@@sixstanger00 I think OP's confusion was due to concentrated helium (lighter than air) filled balloon makes the balloon go up in the air. However the concept the video is referencing is not that (but when any gas filled pressurized balloon has a sudden leak of air, balloon moves in opposite direction).
I actually learned about turbine engines in the 3rd Grade! I'm not sure how, but our Teacher was very knowledgeable about them! She explained turbojets, turbofans and turboprops!

Boy I never tought of myself as of paying memberships on netflix, let alone youtube, but this is the first, , for sure not the last, these channels are simply a blessing, I've been reading the course and I got nothing in my mind....
This deserves a thumbs up. Simple explanation makes it perfect to understand.
The only thing internet explorer and i will not.
I wish I was smart enough to understand how to even build something like this it’s crazy the IQ of the engineers that made them impressive
the flaw here is we see these impressive inventions and forget that this is the result of no less than decades of engineering progress built on top of centuries of math and physics. you probably are smart enough, is what I'm trying to say
It's a collective knowledge by thousands of people rolled into one.Like the Internal combustion engine(ICE) it looks complicated but when you understand how it works it's fairly simple.
It's the product of combined inventions and knowledge. Not a miracle.

An excellent video that clearly explains so much of what is going on with a relaxed delivery style.
has anybody else notice blades are rotating in the wrong direction???
It is obvious.
***** ok you intelligent! one, make your turbines that way, and pray they flay.
No I don't know even one English word.
+Paymaan Jafari YES AND IT MADE ME CRAZY!!! THINGS HAVE TO BE DONE RIGHT IN EDUCATIONAL VIDS!!!
Imagine when in addition to such an obvious mistake, someone tries to convince you it is not wrong! Someone did that for real and tried it even with harshest possible words, look at above and you see some traces of my answers to him, as he has removed his comments :)
Excellent overview given the lenght of the video! A key point that wasn´t stressed enough imho, is the trade-off between speed and fuel consumption that turbo-fans come down to. That solution is at the very center of the economics of aircraft industry. Turbo fans don´t accelrate air as much as a turbo jet does but achieve the needed thrust by moving more air mass in comparison, thanks to a much larger diameter of the fan. The Trust is obtained by multiplying the air flow (kg/s) by the speed gradient. Given the same thrust a turbo fun allows for a smaller turbo-jet component which result in lower compsuntion at the expenses of speed at the noozle.
Isn't that just a propeller aircraft with more steps then?
this video is an amazing introduction to jet engines and turbofan engines. Learned a lot!
One of the best explanation on youtube for Aircraft engine !!
Fantastic!! This is an awesome channel for non-engineers like me to learn *how stuff works*. Keep up the good work!!
The compressor section is spinning the wrong way, but you have the turbine section going the correct way, but the turbine is missing the first stage nozzles. If you go through this much trouble to make an animation shouldn't you at the very least have it vetted by someone to ensure you haven't made an obvious error?
Accurate observation, it is funny how little number of people discovered this obvious mistake.
Okay so it wasn’t just me thinking the animation was wrong.
This was the 1st thing I noticed, I dont how that made it past editing.
@@jaroslawkurzak5379 we arent pilots
First thing I noticed, too.
Great educational video!!! Good for pilots who are studying for the ICAO TEST!!!
Frank Whittle was some kind of genius. Thx 4 the video!
This is a GREAT explanation. Finally I get the grasp of the concept. Thank you.
My Whole aviation internship summed up in a video, marvelous!
We needed this 9 years ago
We needed it now
Yes. The front blades indeed appear to be pitched reversely, to judge by the displayed rotation animation throughout this video. The correct pitch is at last shown briefly at the very end of the video; at about 5:20 min/sec. Thank you very much for taking the time and effort to post this very enlightening video. We appreciate a well-organized and clearly explained documentary. We look forward now to another video that may deal in the Electrical aspect of these same mechanisms; such that explains the Starting System, from beginning to end, perhaps. The Fuel and Acceleration System would also be quite an interesting video to watch, to conclude the understanding of the entire system in basic fundamental concept. Thanks again.

popedpopcorn Thank you for your compliments :)
Visualization is a fun way to learn, comments from authorities on the subject-crucial
lectric2010 Nothing like learning the wrong way
@@Lesics Is what your saying about turbofan engines is that the faster the fan spins the more air it sucks in and it increases thrust?, Basically does the faster the fan spins the higher the thrust will be achieved?, Also does increasing the number of turbines/spools increase thrust?
It kind of feels like a video I would've made in high school.
But with good graphics and animations.
And well done.
Perfect explanation!
thank you learn engineering i really want to become an aircraft engineer when i grow up and you really helped me.

Thank you for the video. It is fantastic.
Very clear concept of jet engine explained by you
I loved all the random directions the arrows were pointing and parts were spinning.
great work
but I think you should mentioned the nozel at the end and the defuser at the beginning
The Aero dynamics of casing don't matter
I still don’t understand anything
That’s mean you are on the right course just keep rewatching
I love how the algorithm seems to know what classes I'm taking in college right now, cause this is straight out of propulsion stuff.
The intake fan is rotating backwards in the animation. At a minimum the intake fan will have be going forward for it to work.

Be carefull about sources, thiv video contains mistakes...
Your explanation is very easy to grasp
I like how youtube recommendations are trying to educate me
Merci pour ce partage ! Vidéo géniale comme d'habitude 😊
the compresor is spining backwords
othman fikri lol I noticed that also, oops lol
othman fikri Came here to say that. High five! :D
They do this so that the engine is stable as well as to keep the air flow smooth. That's why they have the stators and the stator veins.
Valk Stators have nothing to do with keeping the air flow smooth, explain what you are thinking. Stators increase the bite angle of the trailing turbine/compressor veins or blades (whatever you want to call them) so that the air entering the front of the turbine is moving at in an opposite direction, or is at least not turning with the trailing turbine/compressor. This makes the turbine/compressor more effective.
Thad ward That is what I was (kind of) trying to say. I should've said that the stators and stator vanes redirect the airflow as that is what they do.
What a nice explanation video. I wonder what the internet would make of this!
Yes, It was in my reccomendation and no i did not previously look up anything similar to this.
i love on how at the start, the engine rotors aren't even spinning in the right direction
if i compare "Turbo Fan Engine" with an Star combustion Engine from a McDonnel Douglass DC3. the Power went 100x stronger and the idea is more than 100x simpler. oh man, i love these engineers who invented this technic
Wow. This was very informative! Mahalo for sharing
Came here as I’m sitting on a plane bored out of my mind, decided I’d learn the inner workings of the commercial jet engine. Now I can testify in court as an expert, especially bc I stayed at a Holiday Inn Express last night 😂
I think that the fanblade section is spinning in the opposite direction, judging by the design of the blades. Otherwise, good video!
Nice Efforts in presentation......
this is really amazing
So how many Fans do we need?
Engineers of Turbo Jet Engine: Yes
Why are the front rotor blades inverted? Wouldn't that make it spin the wrong direction?
I noticed this too. I think it's what martin said.
At 4:00 the front rotor blade is going in the correct direction. At 5:00 the rotor is still turning in the right direction, but the animation turned the blades 90 degrees in the wrong direction.
Dennis Edwardz Thanks, yeah. I looked back later, and was having problems seeing what I saw the first time. Didn't really feel like going through all that again :P
I have directional dyslexia so I couldn't figure out if i was just confusing myself. When people make mistakes like that, it really fucks my mind over, my brain is suppose to be the source of the inconsistency :P

I didn't know Hillsong produced videos about technology now
What technology / software do you use to create the narration for this video? It is done very well! Were it not for a few nearly indistinguishable grammar flaws, I would not recognize this as a synthesized voice. I work in IT and am very fascinated by the quality of the voice production and would like to know more about how that was done. The video itself was also very interesting and nicely put together.
It's a person? They link the voice actor in the description
I did not expect to understand this, as well as I think I did, after a five minute video.

Hi
"The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is, whichever is greater, it obtains a difference or 'deviation'. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is, to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't."
I'm sorry, this narrator might be the same guy who tries to explain this missile guidance system.
*Can we just appreciate how much time and effort this man puts into his videos!* 😭😭
Only respect to be given here are his skills at animation. But from the standpoint of a turbine engine mechanic (which I am) all I could think was, dang, animation must be much easier than gathering facts. doesn't he know what google is? I mean really, you don't even have to get out of your recliner to get better info than that.
Terima kasih atas ilmu yang kamu berikan guru
Thanks for Knowledge sharing.
Is it me or are the front rotors going the wrong way in this animation? They blow the air away from the motor in stead of sucking it up.
Wrong way I noticed that also I was like....that fan is blowing not sucking

No it's not you, I thought exactly the same thing.
on 04:50, the front blade changed its shape!
Best 2am content
This the type video i will watch at 3 am
1:50 in your animation, it appears that the forward fan blades are pitched backwards.
"Jet engines have been driving aircraft for nearly a century now?" Why were we flying those biplanes in WWI ?
First jet engines were developed in the 40s by the Germans. They also made a rocket plane lol
I was like wtf
The jet engine was invented in U.K. by Sir Frank Whittle in the 1930s. Germans copied. But their WW11 jet aircraft was better than Britain’s. The first British WW11 jet fighters were used to shot down the V1 pilotless bombs.
No this is a video from the future, leaked to us by this kind time traveller who could’ve sold this video for millions, yet decided to post it on RUclips so all of us could be blessed by its knowledge for free.
RUclips recommend me this after 7 years 😄😄😄😄😄
Much more complex than I originally thought
Since the exhaust applies the torque to the turbine that runs the fan, how is it started from rest?
Chris Bogart Good question, for the starting purpose we have to use an electric motor. The electric motor will run the main shaft until enough air flow is achieved in compressor and combustion chamber. After that the fuel can self ignite and sustain the operation.
Chris Bogart Depends on the engine, usually involves spinning up the HP shaft in some way, then when enough air is going through - engaging the igniters and introducing fuel.
The spinning up of the shaft can be done in several ways. Quite a common one is the air turbine starter, which is a small turbine attached to a reduction gearbox, spinning the accessory shaft which attaches to the HP shaft (it drives accessories like the oil pump when the engine is running). You can take that air from the aircraft's APU (which itself has an electric starter), or a ground based starter. On multi engine aircraft, the one running engine can then supply bleed air from one of its compressors to start the other engines. Some engines (as mentioned by the uploader) use electric motors to spin the accessory shaft, and the RR Olympus uses a hydraulic motor. The air turbine starter is generally more popular however as it can provide a lot of power for its size and weight, and it's fairly simple.
Another way of starting a gas turbine engine is by direct turbine injection. Injecting air directly into the HP turbine causes the engine to spin up the way it does under normal operation, however it usually requires a greater volume of gas than an air turbine starter, which may be unavailable if the APU isn't big enough (or the ground based air supply). This may be done to save on the weight of the air turbine starter and its gearbox (or an electric starter), but as mentioned above - may be impractical, as it requires either a bigger APU (which would make the aircraft heavier) or a dedicated ground starting gas supply, which makes it dependent on external equipment which may not be at every airport
Learn Engineering Most commercial-airliner applications would overheat a starter electric motor. Usually a "start cart" provides compressed air to an air-turbine starter on the engine's gearbox to give it the spin-up it needs to start. Some planes (all ETOPS-compliant ones among them) can start their engines internally using bleed air or hydraulic pressure from their auxiliary power unit. I've only ever seen one electric-motor starter on a commercial jet engine.
