this guy has one clear, well understandable pronounciation
His vocabulary is exemplary. I want to count how many unique words he uses to see how high it is. It's great.
pro·nun·ci·a·tion
[prəˌnənsēˈāSH(ə)n]
NOUN
The way in which a word is pronounced.
@@solarfluxman8810 Oh I am very sorry, I am no native English speaker.
@@Roter_Wolf - I used to make the same pronunciation mistake, until a friend told me the correct way to pronounce pronunciation. I am a native speaker, and it is a common mistake for natives. I didn't mean to detract from your great and very true comment. He is a very clear speaker. I am impressed with the work he does and the quality of his presentations.
Check out minutephysics ... I think the same thing every time I hear him speak.
Next up on Tech Ingredients: making radar absorbent paint for your homemade stealth jet.
Believe it or not, we are working on that!
My "son of the main presenter" and I are developing a non magnetron radio cooker and will have large amounts of GHz radiation to "play with". It looks like wavelength long, conductive carbon fibers in a semi conductor matrix will work.
@@TechIngredients can that be used to make a hat?
Can I put that on my car to defeat speed traps?
@@TechIngredients Oh that is BEAUTIFUL. I cannot wait to see it!
@@jdecar1 Sure, but it's not very useful since a lot of agencies have LIDAR now.
This has to be the most detailed DIY turbojet engine build on the internet. Why yes, yes I will watch all ads in their entirety and give thumbs up.
Thanks! Spread the word.
I take it one step further and click the ads :)
Chad L. I pay 12 bucks a month so that i can live ad free in you tube. I believe ive saved at least 1 years worth of brain washing. Lol 12 bucks means i skip one lunch a month dont hurt as much as an ad kicking in on the apex of my you tube binge.
Then you haven't watched Igor Negoda :)
Hey just so you know you don’t actually have to watch all the ad just at least 30 seconds, TH-cam gets paid for simply serving the ad to give people the option of possibly buying and not on watch time alone. Clicking can help though sometimes.
I'm a Professional Mechanical Engineer, and still my mind is blown away by the presenter's knowledge. Nice job sir.
Im a real Mechanical Engineer, and Im not blown away by this propane fueled Garage Heater...
I'm a make-up wearing girl whose allergic to car and technical stuff but even I understood the presentation. Wish he was my science teacher, maybe I wouldn't have hated high school science. Speaking of haye, I see the troll comment above mine /sigh
@@EnglishTurbines I'm a mechanic and I understood everything he said
@@Raise986 That's great, as long as you understand it's still just a garage heater...It won't make any useful thrust, Propane the way he's using it isn't energy dense enough. It's just an easy demo, but it's not a real Gas Turbine engine capable of making real power....🤔😳😏🇬🇧
I would have loved to have you as a professor back in my college days. It's clear that you have a God-gifted intelligence and are well educated. Importantly, you also have the ability to be able to communicate what you know well.
That explanation about the efficiency of compression was fantastic...
Agreed. My 1st thought watching this "this guy is smart". As i kept watching and listening to those ratios and formulae My second thought was "this guy is really smart." Imagine if all the TH-cam viewers were as smart as him, just IMAGINE how educational and helpful their comments would be. Trolling replaced with PhD level tips and anecdotes. If only...
At 17 minutes, had to pause and say this. Hats off to you sir for this (almost) one take masterpiece. We stand on the shoulders of giants and you've become one of the shoulders I'm standing on. I love listening to people talk who have to slow themselves down because the wealth of knowledge they possess isnt to be taken lightly.
Thank you!
There are very few people I can sit and listen to giving tech explanations for 25+ min no matter how interested I am in the subject.
Your presentation is immaculate as is the neatness of your surrounding and the high quality construction of everything you build. I have to lift my game, a LOT!
Can't wait to see the vid of it running but thanks for the informative description of the design and build.
Thank you!
Ive watched your channel! Excellent stuff!
I absolutely love how every design detail is explained and reasoned out, it drives me nuts how other channels will skim over all that, even in a tutorial (cough cough colin furze). Please never skip the details for the flashy shots (although those are fun too), it's what sets your channel ahead of the rest!
Listening to this as I read your comment, it's safe to say other channels are simply not making those considerations.
It's all about the target audience. Colin Furze tailors his videos to the masses, hence his 7 million plus subscribers. The masses do not understand nor appreciate the complex details and science that goes into Tech Ingredient's projects.
Colin Furze is more entertainment than education.
I'm here for all the juicy details, rather than the flashy fun.
Colin Furze makes me feel conflicted. I know I _should_ like the cool shit that he does, but his over-the-top presentation annoys me.
You don't HAVE to know the details that are explained in this video to build a turbojet. These days you could easily throw together a turbojet and get it to work with some trial and error (cough cough colin furze), but the details allow a design to be planned out and nailed first try, which is why this video is so amazingly valuable. I wouldn't be surprised if the creators you are talking about didn't mention those things because they were simply oblivious!
Amazing, when I did backyard jets in the 80's we didn't bother with all the rocket science but hell we had some huge fun. The more fuel the bigger the smoke & flames, that's the only equation we ran with
Great to see your take on turbocharger jet engines! It's a one stop shop for design criteria. Thanks for putting everything together!
A collaboration between you two would be very special.
A collab with you two would be so....I'll be loocking for the right word for a really long time ;p
That collaboration would be extraordinary!
collab and make it more than 40% efficient at turning fuel combustion energy into exhaust velocity energy
needs more turbine, cowbell aint good enough
I wanna know if they have any patents. Tech ingredients guy prolly does based on his cush lab areas but what about Ben?
Wow someone who understands octane. One in a million.
I _thought_ I understood octane and octane ratings, until somebody asked me how a fuel with a higher octane rating actually allows an engine to make more power, at which point I realised that I didn't actually understand a damn thing. So I went and learned.
You deserve a television show on the Discovery channel or something. Your videos are incredibly well made and highly informative. Thank you for the wonderful content.
Valuable information went out of style a long time ago. Why do you think everyone has a tiktoc account?
Cable Tell Lie Vision wouldn't touch this man, he delivers too much knowledge.
OMFG, the most detailed explanation of a burn chamber ever.
I was toying around with the idea of used oil burners, and I never could understand the great variation in burn chamber design. Most videos are like "and play around with it and make it work for your particular setup", but nobody gives any amount of theory on how to approach this problem, and how to judge various failure modes.
I realize that a burn chamber for an oil burner would be far more complex because of the wider variability in fuel type and quality as well as operating range of the fuel flow and air flow, but at least now I have some sort of glimpse on how to approach the problem. (I hesitate to say that I now have some sort of understanding, 'cause there's nothing i truly understand about it, but hey, it's a starting point).....
There are a only couple of youtube channels that I automatically give an up vote, before watching the video. This channel because of the interesting technologies is one of them. Fantastic content, as always, thank you, and have a great evening yourself.
You explained turbos way way way better than most automotive channels. Thank you.
Beautifully spoken, shot, lit. Someone who understands tech who can actually communicate. That is a very rare thing on TH-cam.
Thank you!
This, enough jargon so you can learn the correct terms, and enough english so you can understand it.
It's very helpful that you differentiate between scientifically calculated parameters, rules of thumb with explained bounding limits and "dark art" design. Without this clarity, a novice might think that this is a mature technology where a design could be calculated and built without testing or iteration and would perform as expected. There's a reason why companies like General Electric, Pratt and Whitney and Rolls-Royce still test new designs.
You have hit on a very important point. Deterministic guidelines provide a foundation for the "rules of thumb". This makes improvements and modifications much easier.
Great explanation of the logic behind the combustion chamber 👍
Thanks!
I've been interested in these homemade turbojets for years. Still can't figure out why the combustion chamber's seem way out of scale to the turbo size.
@Brian Borell Fuel burn speed/combustion air velocity. You want all the fuel to burn within the combustion chamber and never within the turbine. As he says in the video you want fully burned slightly cooled exhaust gas entering the turbine, because combustion temps will exceed the temp threshold of the turbine.
1st time i got it man!
@@beachboardfan9544 I think it's called a flame tube or burner can but judging by your in-depth response I'm thinking you might've known that already.
This was the most awesome usage of turbocharger terms and phrases in the context of a scientific lecture I've ever heard.
I congratulate you Sir. It is always a pleasure to observe your presentations! Through these, my son who recently reached 8 years of age already has a firm grasp of a variety of disciplines that I did not have until my late teens and early twenties. I am in your debt and I will be supporting your efforts going forward!
You are one of the very best content providers that I have ever observed, truly!
My son and I both eagerly await each of your next presentations and we both enjoy informing others of your program.
I sincerely thank you for all of your hard work and hope that you will continue for many years to come!
Return of the father of the son of the main presenter.
Just had a birthday and my wife, got to love her sense of humor, got us some T shirts.
@@TechIngredients You create a quality content and are very good at explaining things. It's pure joy to watch and learn. And the "son of the main presenter" gig was hilarious, almost a trademark by now :)
It's the main presenter's son's father. Got to like this video before even watching it.
I prefer....the father of the son of the....lol... damn right !
I'm my own grandpa.
Och they're both pretty good. The son is learning but he's still really clued up :)
@@davegtar Main presenter Jr. is definitely on the right track. Both are good at what they present in this channel
Everytime.
I am extremely appriciative of the precise language used in every video, thank you for making the mental effort.
I wish I had videos like these growing up, as well as the internet.
Thank you sir for explaining this in such detail.
Great build. The only recommendation I have is clocking the center section so the oil drain is pointed down. Turbochargers use piston ring seals and use gravity to drain the oil. Having the drain on the side will cause the oil to backup and eventually leak into the compressor and turbine housings. Amazing craftsmanship and elegant design! Excited to hear it run.
What a boss. best turbojet video I've seen. he's not just slapping stuff together.
your knowledge is pure gold
I appreciate that your videos are not littered with ads. Very informative.
I love this channel so much. It's amazing to see you grow.
This is a incredibly beautiful turbocharger setup
engineering-ly beautiful setups is what this guy does :D
As a mechanical engineer that opted to take controls courses instead of compressible fluids, this was incredibly interesting and informative. Your presentation style is outstanding, I cant believe how confidently and quickly you can give such a detailed lecture without stumbling.
Also enjoyed the shoutout to diesel efficiency 😅
Thanks!
Love every video you put out. It's hard to find such information dense content on YT anymore. Don't change your style.
Another compelling video - just love your work. Thanks for all you do in such amazing detail. Can but imagine all the time you have invested. Look fwd very much to the next video.
Yes - AgentJZ does some great videos on jet engines.
So much great info in one video! Love your presentation style. Thanks for posting!
Sure!
That demonstration about why higher compression ratios give better efficiency was just brilliant. I've never seen it explained so clearly, making it bleedingly obvious. Great!
Thanks!
Great video as always, looking forward to see the second part.
Thanks! Soon...
Yesssssssss been waiting for this one!!!!! This and the magnetohydrodynamic drive are super interesting
A video you can watch multiple times and still learn something . 😁 awesome test stand setup 👌
It's the owner of the property upon which the main presenters lab is built
I've seen sooooo many turbo jet engines on TH-cam now, each with varying levels of wow factor, but this one is just absolutely *beautiful* :O
This looks like a collab between Clickspring, This Old Tony, and NASA :P It's impressively detailed and so clean looking!
I'm excited for the next episode! :D
99% of TH-cam videos make you start researching a subject to understand the minimally explained subject...Tech Ingredients videos are always satisfying in the depth of explanation of the subject.
I'm sad because I missed to subscribe to this channel... what?... 5-years ago! What an amazing orator and presenter. Hats off to the camera operator as well. I can see he cares to get the shot and isn't adding any background noise with those quick feet. Happy to be here and visit again! Wonderful presentation and subject matter. Looking forward to the test.
We're glad you joined us!
Thanks for the compliments. The camera man often doesn't get the credit he deserves, it's a lot of work.
Great video, thank you!!
One thing that stuck with me about doing custom turbo work is that you should have the oil flow through centre cartridge to be as close to verticle as possible. It looks like your oil flow may be more horizontal? Not sure if this will cause any issues. Most turbochargers can be "clocked" fairly easily to get the oil inlet right up top. Keep up the great work!
One of the top two channels on TH-cam. Applied Science being the other one. (App Sci more about proof of concept, Tech ing more engineering. Together they'd take over the world!). You guys deserve proper funding and if I can ever help with that I will. Not only great content, you guys should run an incubator for tech start ups, something I have done a lot of but in 2019 what we lack globally is investment into the skills base. It tends to be knowledge based investment which has a high failure rate. Good work guys, really great stuff.
"top two channels on TH-cam"
I feel the same way.
Undoubtedly one of the most informative and technically precise turbocharger-jet conversion videos on TH-cam (not to mention the tidiest!).
I've previously heard the various turbocharger design terms used (A/R ratio etc.), but had no idea what they actually meant or how to apply them to a design process. Nice shoutout to AgentJayZ, the fountain of turbine knowledge. The moment I saw the lock-wiring on the combustion chamber baffle plate I was reminded of his excellent video on the subject. Guy has SO MUCH real-world knowledge and such a straightforward no-nonsense presentation. Good stuff!
I could listen to your explanation for hours ! Thanks so much 😊
Damn it - I'm up to date with my watching, and now have to WAIT for the next vid.
Just found your channel, immediately subbed! Thank you sir!
Thanks, that helps!
This man explains in common street layman's terms, simply enough for all of us to understand without need for redundant duplication, varied/various complex terms, some of which border Calculus and the Fourth dimension; Pure Genius! Thanks!
Really an amazing video. Well organized, clear presentation, and of course very interesting content! It never ceases to amaze me how far this channel has come from the laser videos that originally got me hooked.
*Tech Ingredients* What a fantastically educational video, I appreciate your detailed explanations, video style, and calm demeanor. Most interesting video I have seen in a long time!
I was wondering if you'd take it under consideration to do a future build on a PDE (Pulse Detonation Engine) which is inherently different and much more powerful than a pulse jet style engine. They have always been my favorite since the physics of their operation is not entirely known or explained. Thank you again!
We already are. Our poor neighbors...
@@TechIngredients this makes me so very happy. are you going to employ the use of a detonation spiral?
Probably not, they don't last long. We have a small detonation chamber followed by an aperture into the main tube.
@@TechIngredients oh, that's a shame. is the chamber a special shape?
Also, do you think making the spiral hollow and water cooled would help?
"The physics of operation is not entirely understood", what? To my knowledge, the principles are very well understood. The problem that is a bit more difficult is related to starting the cycle.
Is there a form I can sign to make you my uncle? You would literally be the best uncle on planet earth, period.
Been Working on and off on a turbocharger gas turbine engine since H.S. I have already learned so much from your clear and articulate presentation of this project, Thank You!
You're welcome!
I hope you get it working. We will be covering a low speed, high torque turbine to convert this into a turboshaft. You might find more applications for your engine with a rotary output.
This channel has been such a blessing. Youre videos keep getting better and better. I hope you continue to keep growing
Thank you! We are in this for the long haul and such appreciation makes it all worthwhile.
JayZ mention, automatic +1. Was the chanel that made understand how jet engine worked.
The guy just has so much real-world knowledge, and presents it in such a no-nonsense way. Great channel!
Still Waiting on the afterburner video... Also would be awsome to see him make a diesel version
A shout out to whoever is manning the camera. The camera person was spot-on every time; whatever part, area, or component that was being discussed the camera was on it!
Enjoying a glass of wine in the southern hemisphere evening sun and watching one of your videos. Living the dream?? I think so.
Thumbs up just for the intro!!:)
Thanks!
Another great video! Explaining a dry subject in an easily understandable interesting way.
One question though .......
....... Have you talked to the neighbours beforehand this time? ;0)
The build quality on all your projects is truly outstanding, I'm in constant appreciation of how neat, organized and sturdy everything is.
Thank you!
Probably the best explanation of the thermodynamics.No jargon such as enthalpy used and yet I understood entire thing
you may have a dc offset in your audio - when i skip around the video i hear clicks and that is a symptom of dc offset (or a lot of bass rumble). use a high pass filter and dc offset removal on your audio. your audio interface might have a switch for that in hardware or software.
9:30 - No turbocharger is water cooled. All turbos are oil cooled. Some turbos are water-jacketed. There is a difference.
The water jacket, as you said, is not mandatory. You can run a turbo with a water jacket without water and you'll be fine. Since again, it is not there for active cooling.
The water jacket is simply there to prevent oil coking in the event the system is shut down with a very hot turbine housing (as you said). You can avoid oil coking by either running the system for a short period (no water) to cool things down, or apply a water jacket to passively cool after shutdown.
10:22 - Almost no automotive setups have water flowing through the CHRA jacket after shutdown. The process relies on convection.
The turbochargers you are talking about are intercooled. This setup isn't, so what he's doing with water cooling is preventing heat from soaking into the compressor during operation, increasing the efficiency of the turbojet. He's using science, not blind copying from an automotive system comprised of additional components. Yes, he's smarter than you are -- live with it.
Nuh uh!
Amazed at what you do. Your explanation makes so much sense. Thanks for showing this.
If only professors could lecture like this guy. Seriously, learn alot. Very clear and concise.
That's great, thanks!
Will there be a afterburner build for this?
reheat!
Will the true king of random please stand up
You are joking, right?
Who's the King of Random?
This comment didn't age well.
@@MartinBuzon that guy is dead.
Kinda in poor taste being that he passed away
holy shit, someone just explained thermodynamic and i understood it perfectely
This is the very best, most knowledgeable and clearly articulated explanation of factors influencing turbo performance that I have ever seen. Fantastic!
Thank you!
I have a huge Caterpillar turbocharger sitting in my shelf, I scored it on ebay before I did the calculations. It would be to big and sadly it looked like it came from a sunken ship... So I bought a tiny Smart turbocharger, but the seller forgot to mention, that a nut or screw had crushed the compressor wheel. I gave up long time ago...
I am very happy to see you are using a normal sized turbo for this video/upcoming test...that means you have something similar to that caterpillar turbocharger I talked about for the staging you talked about :)
No such thing as too big for a jet you will just make mass power/thrust I'd use it
AgentJayZ will love this!
Though he will point out that a turbine is acted on by air, the "input turbine" is no turbine at all..
An issue of semantics. The design is the same and the process is the same, just reversed. Kinda like a piston in a reciprocating engine.
@@TechIngredients True! Great video! just had him speaking in my mind when you said that ;-)
This is a fantastic series! I love the way you laid out the information on theory and design principles. One stop shop for home shop turbojet design. Subscribed!!
Thank you!
Probably the most interesting thing i've watched on TH-cam.
drag guys heard 145mm turbo and were like "pfff you ever seen a pro mod?"
So i am at 16:44 right now, and i spotted something that might be of interest to you if you wish to puruse this project which i have really enjoyed so far. All the holes bored into the flame bearing vessel, are perpendicular to the flame housing itself. What you end up with are a lot of air pressure being wasted on competing with itself for flame housing presence. - So to speak.
They should also be at a small angle towarads the flame housing itself so that the air pressure you introduce into it, wont cancel itself out competing with itself.
You should see a small boost in performance, nothing major mind you.
You're right! Check out the flame tubes for some of the turbojets on Agent JayZ's channel.
Ohh thank you very very much!
Just stick a steel dowel pin in each hole and bend the steel a few degrees i think your less likely to change the aera of the openings this way and it's a fast way to test.
Which is why the holes on combustion chambers in turbine engines can look like a cheese grater. But more often (which is hard to build in a home shop) the combustion chamber narrows before the secondary and tertiary holes and is the original diameter right after them.
best I've ever heard it explained, plenty of detail not over technical
This was posted in perfect time. I have a final school project coming up for college and I'm really set on building a turbojet for it. Cant wait till the start-up video! Subscribed!
Thanks, that helps.
Such a project will require that you explain the physics that underlies the process. Hopefully, we gave you a jump start on that aspect as well.
You make me feel smart because I fully understand what you're saying
Then you leave me and I face reality
i r sad
"Turbo Chargers..., Do You HAVE to Love Them?"
Sigh... Alright, but I can see right now that this won't end well for me.
:-D
I have never learned this much in 30 mins until I watched your video. Absolutely thankful for all this knowledge.
Thanks!
You might find some of our other videos to be interesting. We try to produce material that is content rich and even topics you don't usually follow may be eye opening.
Funny how you find the video with the best explanation of turbocharger specifications in a non-engine/racing specific channel... although I'm not that surprised I guess, this man is the king of demonstration videos and fundamental concepts conveying for a wide range of subject matter!
Thanks!
I really don't understand the people who disliked this video ?????!!!!
They don't have the patience for his words.
Or maybe they see through his nice presentation. Yes, he does very nice things and i respect all the projects, but he is definetly overselling them. The builds are beautiful but as someone with a bit of backround knowledge you will understand that he does not know much more then most others who have done videos on these subjects. Dont get me wrong, his videos are very nice and most likely an inspiration to many but he is not the wise guy he is pretending to be, so some may be offended by it and see him as a poser.@@captainTubes
It seems to me that being offended is an art form in itself nowadays. I'm not dissing your post btw which I find insightful.
Offended was most likely not the best choice of words.@@theflyingfool
@@NIOC630 He plainly said in the video that his presentation and build was based on a synthesis of information from websites and forums that he had scoured. That proves that he is not in any way "pretending to be" a "wise guy". Your comment seems disingenuous to me. Either that or you didn't watch the video.
I watched some of your videos. Nice engines! But you give no information. Maybe you are a member of some of those forums he learned from and your videos are cited in your posts there? At any rate, your videos on their own are useless for learning anything as far as I can see.
colin furze: "hold my tea"
That's hilarious!
You mean, “Hold my loo holder”?
One of the best engineering explanation videos I've ever seen, it helped improve my understanding of so many different sub-topics that I wouldn't have expected from the just the title!
You might enjoy some of our other videos. The content is much denser than the titles imply.
Crystal clear explanation of turbocharger operation. This guy is an amazing teacher. All his videos are great!
Thank you!
16 dislikes come from the pee-ons who think they know it all. Great vid yet again Tech Ingredients!
I've rarely seen someone describe tech. things so well. Thanks.
Much great info as usual! In terms of automotive applications I had heard generally why compound turbos are a thing and why you need to properly size your turbo to your engine but its nice to here a more technical explanation. Love your content!
This is easily one of the most interesting videos I have seen in a long, long time. You have my enthusiastic subscription!
Thanks and welcome!
This channel has the smallest perception time to wall time ratio I have seen and yet it is so calm and orderly =)
He reminds me of my grandfather, talking to me when I was super young. I had no idea WTF he was talking about, but I sat there intrigued by his passion.
Thanks from the Uk. What an excellent Teacher, Explains everything so well Its really given me a lift, And when I've finish my jet powered go cart I'm gonna be flying. I always wanted a teacher like this when I was a school, Oh well never to late to learn, TY!.
Always excited for new content from tech ingredients! Can't wait for the next one.
I am blown away by the presentation and engineering detail of this build. More over, many rules of turbo charging, no matter the application, are brought to light.
Thanks!
Prodigious is such a good way of describing how much this thing sucks fuel. Such a great word choice!
"We've got some pretty interesting applications" Awesome, looking forward to it!
That thermodynamic demo was a real lightbulb moment for me. Great stuff.
Thank you for not being like some others who explain things in the most difficult way possible to sound smarter than they are, this is truly rich and legit.
I like that you speak CONCEPTS instead of just numbers and math alone, it really helps a lot. #liked
I love how those videos distill and present a massive amount of internet research in a complete and comprehensive manner. I dread to think about the endless hours of forum reading all this takes.
There is a lot, but that's what I like to do, it isn't a chore.
@@TechIngredients I totally understand (countless sleepless nights online can attest to that). Also no one does all this research for the "TH-cam-viewcount". It must, first and foremost, be something you enjoy!
