So glad this guy went on to narrate every movie trailer in the 90s. What a legendary career.

Kinda lied in my application to Boeing saying I'm a jet engine specialist, first day on the job is tomorrow and this video is really teaching me something. Wish me luck 🙏

The best explanation ever of a phisycs topic. Good old XX century style, when content mattered more than superficial entertainment.

One of the most valuable jewel found in the internet. The best learning experience about jet engines. The old school presentation was a truly top gun teaching in the subject matter. Thanks so much for sharing.

Love these old educational videos. This is very clear on the basics of jet engines. Wish I had found it years ago.

If all my professors were like this guy I would’ve had 5 Nobel prizes by now

Finally, a competent and comprehensive explanation! It's sad so many of the modern videos on the workings of jet engines, with their CG animations (some with the blades actually spinning the wrong way), are actually so superficial in commentary and content, they fall so short when compared to this video - one that must have been made ~40 years ago, but with actual in-depth knowledge of the topic. What a difference it makes.

Superb, absolutely spot on presentation with perfectly paced detailed and fluid delivery. I was hooked from the start to finish. Thank you for posting.

These old school presentations beat the pants off our more modern ones. I wonder what went wrong.

Everything goes in the inlet of the engine, the rain, the snow, the ice AND the birds 🤕

I found this to be a excellent presentation explaining the basic principles of how a turbine engine works, and the various types of turbine engines .

Fantastic! This has the same quality of the old Jam Handy instructional films from the 30’s-50’s. Prelinger archives has tons of stuff like this; absolutely fascinating explanations of commonplace things mostly taken for granted.

This was SO good! I'm jealous of who could watch this back in the 1980's...

Absolutely fantastic presentation. Wish I had seen it as a teen ( when it was obviously produced)... Might have changed my future. Thank you for this education, many, many years later.

better than most school lectures today who agrees

Priceless Instructional Video Extremely well Presented 👍 ...

Jet engines don't suck! I love them...

This is truly priceless to anyone trying to understand these topics.

Never have jet engine fundamentals been presented so simply. This is a very useful video

I worked at a model company back in 83. We built a model very similar to that one. It was a PW F100

A superb lecture, not just the best on jet engines, but one of the best lectures on any subject.

I put JP-7 in my car and it went around the block in 3 seconds. That stuff is great.

This answers so many questions I had! Thanks for uploading it. 👍🏻😀🇬🇧

This explains a very complicated concept in a very easy to understand way without glossing over information

An Excellent Video, Great Lecture, Inspiring & Pumping, must watch by all the Aerospace Propulsion Engineers

A good example of turboshaft engines are the RR/Allison 250C engines that power the MD500 or Bell Jet Ranger helicopters, a sweet sound on start-up, I must say.

The history of the jet engine is actually fascinating, especially when you consider it was turned down for years during the war and the developer had basically no funding and had to work in a derelict workshop

Focusing on a lengthy lecture has never been this easy. Easily the best lecture ever. Thank you for uploading!

best jet engine learning in the internet. thanks for sharing this.

Excelent explanation , it can not be found nowadays, something has been lost in modern teaching

This reminds me of the class I had when I got a job on the assembly floor at P&WA in 1977. I assembled JT8s and JT9s. I’ve been in test cell control rooms. Some of those guys in there are probably working for the customer. We used to see someone from the airplane company and the airline buying that plane.

Great vid. Absolutely rocking comb-over.

I thoroughly enjoyed this class! So detailed! Learned a lot!

Thank you very very much for this wonderful and eye-opening explanation about jet engines!!

Reading the comments reveals a lot about the people who watch YT videos.... THIS VIDEO IS INTENDED FOR GENERAL AUDIENCE NOT FOR ENGINEERS! If you throw Thermodynamics, aerodynamics, work, energy, momentum at the common mortal, he will stop watching. This is a well explained PRINCIPLE of how jet engines work! It is well spoken and shows in a simple way how this works.

The best and most through explinations

An excellent lecture. Love the old-school productions. Explains with just enough depth for an introduction course. Love it!

THIS IS A TRUE, INSTRUCTIONAL KNOWLEDGE, I LOVE IT, AND ALL A JEWEL OF KNOWLEDGE WITH AERO SPACE TECHNOLOGY ...

Very good explanation how a jet engine works !

This video has orders of magnitude more instructive value than all of the turbo encabulator videos put together.

Outstanding presentation!

What a comprehensive lecture. Marvelous to say the least. 🎉🎉🎉

Nice video covering the basics. 👍👏.

Awesome video. Modern videos can't compete.

This is Gold ! YT is amazing for educational clips like this, I save these in a dedicated playlist

Very informative and eloquent. Thanks

Worked at P&W from the late 80's thru the late 90's....I took a textbook directed version of this course but, either way, it is very nice coverage of the basic engine architecture as well as the thermodynamic & aerodynamic principles of jet engines. Fun product to work on....as a mechanical engineer, there are few jobs where you can get your hands on this much horsepower right out of school.

Thank thank , this is an excellent video.

Great document!

I learned a lot from this lecture.

This is a great informative video. I like this man's demeanor.

I really happy to got recomendation from KZfaq for this video only. 🔥🔥

This is great I learned a lot 💯👍🏾

Surprised at some of the terms. Perhaps I'm just younger and there's newer terms now? The After Burner is also called a 'Reheat'. The after burned section is sometimes referred to as a 'Flame Tube' or 'Reheat Section' or 'Reheat Tube', since it's literally just a tube. An empty can. Though it does use a jacket. The C-D Nozzel exit is also called an 'Ejector'. If the C-D nozzle is a variable one its a 'Variable CD Ejector'. Flame holders are briefly gone over here and I don't know if the description was adequate? The Flame Holdsr purposely causes turbulent air that spirals and stalls, for mixing and for maintaining the flame. Air that is super sonic will blow out the flame. Why? Because the Flame can only ignite so fast - there are two terms here, Flame front and Flame Propagation. It might surprise people to know but... for those of us Americans whom love our guns? We can tell you that we actually prefer slower burning powder better than faster powders for the charge. The slower power allows pressure to build and ultimate leads to better performance of muzzle velocities in most cases. The jet engine is no different. We are simply shooting a stream of air out the barrel instead of a bullet. The limit, though, is in reverse. If the air + fuel mixture can only propagate the flame front so quickly, then we need to slow down the air that's being ignited like we want to reduce the burn rate of an charge for a bullet. If we don't, the air will be moving too fast and out run the speed in which the flame propagates, and thus you have a flame out. Flame holders are of use in Combustion Chambers as well, depending on the engine. They're primarily to agitate and cause turbulence for more adequate mixing. The CD variable Nozzle and the Tube jacket are not just for accelerating or decelerating the ejected air stream. Ambient pressure can cause back pressure to occur and the bleed air from the jacket, provided by the bypass air, as well as the use of the variable nozzle ejector, all try to balance out that possible back pressure to ensure more efficient 'ejection' of the air stream. Remember, your goal is to not only throw as much air out the back as possible, Thrust = MxA of course... but you also want to make sure that you're imparting as much of that thrust to the engine's structure itself. It makes no use if you're throwing out so much thrust but have the thrust be diluted due to going off in all directions. You want to make sure all that thrust is pushing on your engine in the one, singular direction so that you're getting the maximum physical reaction out of that thrust mass.

This channel deserves multi million subscribers..

Wow, this is pretty good!!! A primer before people go to channels like AgentJayZ LOL

this one here is truly a gem

Thanks for this wonderful explanation.

A really good documentary .one which I enjoyed watching a lot

Excellent presentation

It’s an oldie but a goodie.

Great lecture I love it

Very, very cool vídeo ! 👍🏻👍🏻👍🏻

wow this is super easy to understand thanks!

Using a bullet recoil as an example of jet propulsion ... nice

Yes Boss! Every action has a same reaction.

What year was this made? It's so fascinating to me to see these older videos

Amazing.

I like his continuously sarcastic and condescending superior tone of voice 😂

I'm gonna fall asleep so hard to this later. Thanks for the upload, excel spreadsheet videos stopped working after a while.

Excellent video! Explained so much in detail and easy to follow. Best I’ve seen of all the youtube jet videos. Yet the one question I’ve had for years remains unanswered. With a rocket, it’s easy to see that the combustion gases push against the rocket nozzle itself, thus transferring thrust to the superstructure. With a turbojet, ALL the videos and explanations just say “Newtons Law”, gas jets out the back and gives forward thrust. But exactly WHAT is the exhaust gas “pushing against”? The best I can imagine is most is pushing against the forward structures of the combustion chambers, and a good portion is also effectively pushing against the compressed air at the last stage of the compressor. I imagine the compressed air forms a stationary front, just aft of the final blade wheel. And since exhaust gas cant really ‘push’ against air (another gas), it is actually the spinning compressor blades “generating” the “thrust” as they maintain 20-40 ATM compressed air pressure. Thus the “thrust” is actually ultimately generated in the main rotor itself, and transferred to the superstructure by the bearing system. I recall on commercial flights, at takeoff, the engines whine higher and higher and higher - then there’s a sudden ‘boom’ and solid roar - I think that is the stationary compressed air front forming and reaching static equilibrium with the combustion front. Anyone can comment on this?

I love instructional videos like this, and especially this authority voice :D

Very informative

Very pleased that this was recommended to me 👌

I learnt a lot from this video, I thank I'll be a jet mechanik

I need this video because i am building a mig and flying to the edge of the armosphere.

Nothing better than this. I call the approach Simplistic Conceptualization. Offfical term ? Everything is good but the concept is even clearer when slowly emphasizes that in supersonic mode, the convergent/divergent principle is reverse. Also air enters into the engine front end needs to be subsonic. That explains why the nozzle throat is that way and why the nozzle opens in after-burner (supersonic) mode.

I love this Jewel 💎

nice presentation of axial combustolators

That cop really looks like he means business

Im 47 years old and today watched this for the first time. Call me a slow starter!

Rolls Royce employed three spools on their large engines if I'm not mistaken=Low-Intermediate-High pressure.

The best video,

One question I have about this explanation is why the combustion exhaust all seems to go out the exhaust. The combusting gases would go in all directions, so some would go forward too.

Thank you so much professor

This is glorious.

Found it! I watched this when I was in high school and have been looking for it for a long time!

good job

How to explain the workings of a jet engine in 4 words. Suck/Squeeze/Bang/Blow. Easy peasy.

I thought for a second this would be a sales pitch for people who wanted to generate inverse reactive current for unilateral phase detractors

Genious.

This is definitely AgentJayZ's dad. I just wish the first stage blades weren't seized on all these engines, just think how much faster it would go with all blades spinning.

😮❤ dual rotar Engines

Great exposition of the jet engine. I would only add that it would have been far more understandable, for me at least, if instead of a balloon, they had started the comparison of the jet engine combusters with the rocket engine with which the jet engine is an obvious descendant.

Wow now I know how jet engines work

Esme Sara khel right quantity of fuel (input )+ parts aceept that input without any problem , and exhaust and sound comes in a right sequence

easy to understand

Maid malotto in paranoid pig iron, an excellent thinking putty's sir.

A visually, educationally great presentation! one constructive criticism: there seems to be a conspicuous absence of any information on the turbo encabulator. Otherwise though, it’s Huell-Hauser-level gold :)
