The first turbocharger turbojet I saw was at a railway equipment show more than 20 years ago. A platform mounted on small rail wheels had two of these jets on one end aimed down at a 45 degree angle. the machine was used in railway switching yards to blow snow and ice from the switches to prevent them from being frozen in place. The jets didn't propel the platform. It was pushed from switch to switch by another vehicle. I have been fascinated by turbocharger turbojets ever since.

I was wondering if the compound turbo turbines, will quiet it down, or will a multi-stage generator turbine quiet it down, or, is there a tuned muffler that can be made for it.
@@observingrogue7652 a turbine attached at the end to capture power will make it quieter and the more energy it pulls out of the exhaust the quieter it will be. Without a multistage turbine it will likely just sound like a smaller engine but even with a very efficient design eventually it's just not worth the effort of capturing it. In this case exhaust restrictions to quiet it aren't really an option because they reduce the efficiency upstream. Another turbine is a restriction but its neccessary to extract the power. Many power plants will actually use the last heat to power a steam turbine, extracting power at multiple stages in different ways as the energy lowers. With the dregs of heat left (still enough to burn stuff) you could heat a huge water heater then heat a building in winter and then a bank of sterling engines. As the temperature goes down there will be a point where the energy recovered will equal the amount lost in the system recovering it. That point is FAR beyond the point where it is economical to try to recover any more

Honestly cant think of a more thorough and comprehensive science based channel across the whole of youtube. love the valved 50lb thrust pulse jet in the background btw. i built one from maddox plans a few years ago.

Brilliant as per usual. You set a VERY high standard for the content you have in your Vids. I'm looking forward to seeing what you come up with for the liquid fuel. Not many people have done that and to me it's really where these engines go from experimenting to serious and creditable setups. Seems to me that the setup you have now would work just fine although you may need a preheat with gas then change over depending on what you use for liquid fuel. I build waste oil burners based on the same principal of Phase change from a liquid to a gas using retained heat in the combustion chamber. I'd like to be able to work out a flame Holder and do a burner that kept the combustion suspended like you have. The Evaporating back plate and the exit path to bring the flame back on itself is a great idea. Thanks again for the informative and educational vid. You always manage to make learning interesting which is a significant achievement in itself. Btw, The chicken needs to go on a Rotisserie and you need to change the output Nozzle to a 12" diameter to slow the gas speed and stop the chicken from blowing apart when it is done. :0) Maybe put a nozzle in the output pipe so the the basting can be sprayed evenly on in the jet wash. When the chicken was done, with an igniter you could swap the basting for fuel and have an after burner! :0)
Good ideas. The liquid fuel works great right from the start without any pre heat or multiple fuel requirement. As we'll show. Recycled deep fryer oil fuel would be ideal for chicken and beef, I'm not so sure about fish...
I just found this channel last night and I am in love. I'm a mechanical engineer by trade and this content hits me right in the warm, nerdy, center of my being.
Thanks for making these high quality content videos. Sometimes I just don't know what I don't know, and your videos often give me ideas to explore that fill in the blanks! You are appreciated greatly!
I love your fluent physics based explanation. It makes so easy to follow. Wish I would have known all this when we trial runned our turbochargers something like 25 years ago. Got a lot of diesel vapour smoke and noise of course. But nothing as close stable performance as this!
These videos are helping me understand practical applications of engineering principles, it's like aerospace version of the 'practical engineering' channel. I do need to brush up on fluid and thermodynamics theory.
thank you for all your knowledge that you and your son are sharing! I hope you continue to teach until the end of your days- you are the science teacher I never had but always wanted. If this video is proof, its never too late to enjoy doing what you enjoy doing! God Bless you sir
Man, those sounds bring back fond memories of when I, as an Air Force missile maintenance technician, used to run the GE-J85 engines on ADM20C Quail missiles in the 1970s.........
I am following ALL your engine build videos. I have a frame that I'd like to attach one to but I'm still learning a bit about their workings before I dive in. You've been a great help so far!
Hello I'm an aircraft engine inspector (internal components) of 4 years and engine assembler (both new an used) at a major manufacturer. Let me know if you have any questions. BTW we run engines with a type of refined kerosene, we push fuel through many fuel nozzles around the combustion chamber, the fuel nozzle have a pattern of holes machined inside of them to mix and swirl and air fuel together. We push fuel through high pressure teflon lines, with stainless steel braid then covered with a 0.125" thick later of RTV silicon. The fuel pressures are hydraulic ranges 1000 to 3000 psi, throttling the fuel is more complex than just a valve if you want to attain high efficiency, you will at least need shaft speed sensors. You should redesign the combustion chamber and turbine support case to allow linear flow.
Love the videos always! On the topic of propane: a recent project I was on built some pretty incredible pulsejets which originally ran on liquid propane. We also had problems with the liquid (although different than yours: we had problems with actually vaporizing the fuel to burn it. In fact one of the coolest things I've ever seen was a glowing red hot expansion chamber...with frost on the bottom! The temp gradient was insane!). We, like you, moved to vapor propane instead, and have lots of experience working with it as a fuel. If you did want to stay with vapor propane, an option could be to place the propane tank in a bath of warm water, and then use waste heat form the engine to keep the water warm when the tank starts to freeze.
Very true what you are saying about the thrust produced in these homemade turbo engines. I remember one guy who used a turbine from a turbocharger in line with his homemade turbojet to extract the power to power his gocart, but I can't remember where the project went or how it ended. Keep it coming!
16:05 love that moment! Highly entertaining and educational videos which makes your channel very unique to me. Thank you for sharing your awesome projects!
I certainly enjoy all your content, so I look forward to seeing more. Been subscribed for a while, through speakers, generators, and all and gained a lot of enjoyable insights. Thank you very much.
You know, some people become rich and famous just to have a fan like this. It does however remind me of my mother in law when she gets on her hobby horse. Fascinating!!! Thank you both 😎
Oh dang! I wish I was paying more attention in the last video in regards to the propane surging issues. I used to work on grain dryers (Vertec) and one of the main heating methods that they used were indeed liquid propane. One of the methods that they used for a more consistent burn was a 'Vaporizor' essentially prior to sending the fuel to get burnt, it would be passed into a hot zone (in front of the burner) wherein the liquid would turn to a vapor, guaranteeing the burn. Would be fun to experiment with wrapping a stainless fuel line around the burner housing you have prior to feeding it to allow the LP to turn.
Be carful getting graphite on the combustion chamber, you'll burn holes on it wherever the graphite contacts. I rebuild turbine engines from helicopters and I've seen guys mark things with a pencil and you can see exactly what they wrote after the engine heats up and anywhere the graphite was there's no longer metal
since finding your channel i have watched almost every single one of them, they are extremely educational and your ability to explain complex principles and problems is astounding. you should do a collaboration video with a channel like smarter every day or Mark Rober or one of your favorite channels, thanks.
Propane fueled recip engines usually have engine coolant heated regulators to maintain stable output pressures and to help vaporization. In future builds that might be worth looking into and/or bleeding off a bit of warm/hot air from somewhere to warm the supply tank. Can't wait to see this coupled to a matching power-take-off turbine. Your grand-finale should be a steam turbine powered by all the waste heat for your very own miniature combined cycle power plant!
With most RC turbines there's no fan infront of the RC centrifugal compressor blades, it's just the motor tied directly to the rotor. When the turbine shuts off, the motor remains on for cooling and it also acts as a flywheel+alternator.
I HAD MY HEADPHONES AND MY WIFE SAID "WHAT THE HELL ARE YOU LISTENING TO?" WHAT A MISTAKE THAT QUESTION WAS... I SPENT THE NEXT 30 MINUTES EXPLAINING IT TO HER!! HA! HA! SHE DOESN'T ASK ME ANY MORE QUESTIONS!! : )
I noticed that surging issue in the first video, and it reminded me exactly of the same issue with liquid and gas fueled camp stoves; in liquid feed mode at reduced pressures you end up with what seems like pressure resonance creating an inconsistent burn (as you said due to inconsistent vaporization, and presumably resulting backpressure), and in gas feed mode, it runs beautifully. Some stoves get around this by reducing the volume between the valve and the atomizer.
He mentioned that the combustion chamber is small with small turbos which makes it less efficient Isnt it possible to use the large combustion chamber on the small turbo??
Pretty impressive! I would love to see what you do next with both types of jet engine. If you were my neighbour, you would have trouble with keeping me away from your tests! Thanks for the work / fun / effort / time / money that you put into providing these videos. 🙂👍
Right at the end of the video with the piece of wood at the exhaust nozzle, made the think of roasting the oak for your whisky video. Maybe you're on to something there. ;-) Great video as always!
Hi, First of all, thanks to you for explaining the basics of turbo jet engine nice demonstration..your channel is the first one i am subscribing...keep going..all the best
I had to chuckle at your little hop while standing in the exhaust. You look like the quintessential kid in a candy shop. I am jealous of your playtoys!
It'll be very interesting to see the compound version, higher pressure means more fuel and air fits in a smaller area, effectively making the combustion chamber much larger. I'd still rather see a SPRF style combustion chamber, with concentric layers around the combustion chamber, and a 1000psi water injection system which would create additional exhaust volume and reduce heat stress on the turbine side. Also, keep in mind that, all that noise is caused by turbulence, which reduces efficiency. .
I wasn't referring to Turbo whine, although that is also a reducible noise, I was referring to Combustion Turbulence Noise, which is caused by a variety of factors, and which can be reduced, with a measurable bump in efficiency. I was just giving him another point to research, which creates better overall understanding.
I wasn't just referring to the 'whine' as you call it but the vibration in the air being compressed by the turbo has cavitation like water does when you spin a propeller too fast compounded by the non linear path of the air creating a turbulent flow then the explosive expansion of the heated air on the combustion chamber then the restriction of the jet nozzle. Making it quieter is daunting to say the least and any progress on that path would ultimately be futile as it would be minuscule in volume change anyway
Main presenter, if you really wanted to use liquid propane, have you considered running your fuel line (metal fuel line obviously) around the flame tube or exhaust in the form of some heat exchanging coils to convert your liquid supply to vapor before being burned? This is what we do in hot air balloon burners. Also, call up some hot air balloon pilots and ask if they have or have a line on some illegal (to fly) propane tanks they want to get rid of. They're 10 gallon propane tanks with liquid and vapor taps. Quite handy.
The source of the tanks is a good suggestion. The heating of the fuel posses some challenges. It needs to be effective and therefore the lines need to be long enough and be immersed in the hot gasses, but not obstruct flow. If the fuel expands too much the flow resistance can choke the fuel flow.
Seyton, I understand!! If I met you, I would the possibility & a way to do it!! There is no such thing as perfection and everything is possible!! Remember only one certainty in life is death & at so at some point in life, we all run out of time!1 Take it vantage of what you have!! I wish you the best!!!
AGREED 1,000,000%!!!! HE'S ON THE SAME LEVEL AS DR. CHUCK MISSLER (deceased) WHO IS INCREDIBLE ON EXPLAINING THE MYSTERIES OF THE BIBLE!! I'VE BEEN WATCHING HIS VIDEOS ON RUclips... AND NOW I'M HOOKED ON TECH INGREDIENTS!!!! : )
Why would ANYONE downvote this video? This is absolutely wonderful, I could see this being incredibly useful. Perhaps running off methane from a digester it could be used to supplement a solar/wind source with zero fossil carbon. Not to mention just the fun of putting something like this on a little cart or cycle!
Good to see you stepped up to a big boy! Just happened to complete work on my phase one engine while building up parts for phase 2 (a 7" dual compressor axial design that I'm scratch building) today and wondered if you ever did anything else with your build. Couldn't agree more with your synopsis on the pitfalls of using an automotive turbo for these, but it does take a lot of manufacturing of precision parts out of the equation. On the subject of LP/gaseous fuels, the engine testing groups use a fuel warming system that's rather elaborate to get around the cooling issue, though for us backyard guys, a kiddie pool filled with water and a heating element works equally well based on scale of our supply. I had a reptile heating pad from a fermenting project long ago that I used, as it maintains a good 120* F quiet easily, but a resourceful gent such as yourself could easily rig up something with a bit more grunt. You could also go overboard and build an insulated and heated holding chamber, but the kiddie pool is much more practical. I really liked your approach with the 'injection plate' idea as I came up with something similar for my phase 2 engine, though quite different in deployment as its designed around running hydrogen fuel at a good bit of pressure. Keep at it as I'm looking forward to seeing your compound operation with a free power turbine take shape one day!
Thanks! We've gone on to test the engine with both methanol and isopropyl alcohol. It works at least as well as with the propane, requires no warming or propane to start and works well with the plate diffuser too. Oh, and be careful of parallel turbos. Just like parallel diodes, a small difference in the performance between the two can lead to a runaway seasaaw. Personally, I'd recommend going to series operation and reaping the added benefit of increased effeciency.
@@TechIngredients Ah, very smart with your fuel swap, sir, and thank you for the advice! My larger engine will actually be kind of a hybrid, as an axial arrangement with compound components. I suspect there's a reason the pros don't do this, but for the sake of experimentation and not having to drive 6-7 rows of parasitic compressors, I'm having a go. =) Add: I did have a brief research period of looking at actual compound turbo setups, and you are right on the money with how those things are sized and oriented. In my build up of parts for the first engine I happened to land some large compressor wheels from what I suspect were APU units, which is why I'm going a different route. Who knows, with a bit of work and a massive stroke of luck, it could be revolutionary (probably not though; it'd be tough to outdo the Williams-era engines!) in small jet engine design.

On a more serious note, increasing the exhaust mass as a means of increasing engine thrust (and efficiency) is very clearly seen on the increased bypass ratio on turbofans. They started out low, but they're now as high as 11:1 or even more on the GEnx and Trent 1100 engines, which means that only 1/11th of the mass passing through the engine is used for combustion, and the rest is just propelled out the back by the enormous fan.

I'm looking forward to seeing what you come up with for the liquid fuel. Not many people have done that and to me it's really where these engines go from experimenting to serious and creditable setups. Seems to me that the setup you have now would work just fine although you may need a preheat with gas then change over depending on what you use for liquid fuel.
I build waste oil burners based on the same principal of Phase change from a liquid to a gas using retained heat in the combustion chamber. I'd like to be able to work out a flame Holder and do a burner that kept the combustion suspended like you have. The Evaporating back plate and the exit path to bring the flame back on itself is a great idea.
Thanks again for the informative and educational vid. You always manage to make learning interesting which is a significant achievement in itself.
Btw, The chicken needs to go on a Rotisserie and you need to change the output Nozzle to a 12" diameter to slow the gas speed and stop the chicken from blowing apart when it is done. :0) Maybe put a nozzle in the output pipe so the the basting can be sprayed evenly on in the jet wash. When the chicken was done, with an igniter you could swap the basting for fuel and have an after burner! :0)
Good ideas.
The liquid fuel works great right from the start without any pre heat or multiple fuel requirement. As we'll show.
Recycled deep fryer oil fuel would be ideal for chicken and beef, I'm not so sure about fish...
I love what you’ve done on so many levels !!!! Please, Please, Please don’t stop what you’re doing !!!
I just found this channel last night and I am in love. I'm a mechanical engineer by trade and this content hits me right in the warm, nerdy, center of my being.
Fantastic!
After 1.5 years and I still am waiting the new video, the most awaited video!
Thank you so much, can’t wait for the next one.
Thanks for making these high quality content videos. Sometimes I just don't know what I don't know, and your videos often give me ideas to explore that fill in the blanks! You are appreciated greatly!
This is the greatest intro to a RUclips video in the history of RUclips video intros.
You guys are the best, I love you
I love your fluent physics based explanation. It makes so easy to follow. Wish I would have known all this when we trial runned our turbochargers something like 25 years ago. Got a lot of diesel vapour smoke and noise of course. But nothing as close stable performance as this!
These videos are helping me understand practical applications of engineering principles, it's like aerospace version of the 'practical engineering' channel. I do need to brush up on fluid and thermodynamics theory.
I'm happy to see another video from my favourite channel
I'M "HOOKED".... CAN'T GET ENOUGH AND WATCH OVER AND OVER TO TRY AND LEARN SOME "TRICKS" FOR MY REAL ESTATE PROJECTS!
thank you for all your knowledge that you and your son are sharing! I hope you continue to teach until the end of your days- you are the science teacher I never had but always wanted. If this video is proof, its never too late to enjoy doing what you enjoy doing! God Bless you sir
Thank you guys for the quality content of this channel. Keep up the good work.
"dangerously loud. It's a beautiful thing.. " Priceless :) Keep it coming !
Man, those sounds bring back fond memories of when I, as an Air Force missile maintenance technician, used to run the GE-J85 engines on ADM20C Quail missiles in the 1970s.........
I am following ALL your engine build videos. I have a frame that I'd like to attach one to but I'm still learning a bit about their workings before I dive in.
You've been a great help so far!
This turbojet is the best series ! can't wait to see the new episodes !
Beautiful work and wonderful presentation! Thank you for making this, and the video!
Hello I'm an aircraft engine inspector (internal components) of 4 years and engine assembler (both new an used) at a major manufacturer. Let me know if you have any questions.
BTW we run engines with a type of refined kerosene, we push fuel through many fuel nozzles around the combustion chamber, the fuel nozzle have a pattern of holes machined inside of them to mix and swirl and air fuel together. We push fuel through high pressure teflon lines, with stainless steel braid then covered with a 0.125" thick later of RTV silicon. The fuel pressures are hydraulic ranges 1000 to 3000 psi, throttling the fuel is more complex than just a valve if you want to attain high efficiency, you will at least need shaft speed sensors.
You should redesign the combustion chamber and turbine support case to allow linear flow.
Beautiful work.
I really love how happy that thing makes you.
Such an exciting project, I am really looking forward to more. Can't wait.
Love the videos always! On the topic of propane: a recent project I was on built some pretty incredible pulsejets which originally ran on liquid propane. We also had problems with the liquid (although different than yours: we had problems with actually vaporizing the fuel to burn it. In fact one of the coolest things I've ever seen was a glowing red hot expansion chamber...with frost on the bottom! The temp gradient was insane!). We, like you, moved to vapor propane instead, and have lots of experience working with it as a fuel. If you did want to stay with vapor propane, an option could be to place the propane tank in a bath of warm water, and then use waste heat form the engine to keep the water warm when the tank starts to freeze.
Very true what you are saying about the thrust produced in these homemade turbo engines.
I remember one guy who used a turbine from a turbocharger in line with his homemade turbojet to extract the power to power his gocart, but I can't remember where the project went or how it ended.
Keep it coming!
Bro, you have to be one of the coolest guys on RUclips. Thank you for the content and education.
When you’re having fun, i’m having fun
16:05 love that moment! Highly entertaining and educational videos which makes your channel very unique to me. Thank you for sharing your awesome projects!
I certainly enjoy all your content, so I look forward to seeing more. Been subscribed for a while, through speakers, generators, and all and gained a lot of enjoyable insights. Thank you very much.
Thanks!
You know, some people become rich and famous just to have a fan like this. It does however remind me of my mother in law when she gets on her hobby horse. Fascinating!!! Thank you both 😎
This is awesome!...and one of the highlights is @16:07 "...it's just, ha, it's a beautiful thing..." Priceless!
Thank you for sharing all you do!
Oh dang! I wish I was paying more attention in the last video in regards to the propane surging issues. I used to work on grain dryers (Vertec) and one of the main heating methods that they used were indeed liquid propane. One of the methods that they used for a more consistent burn was a 'Vaporizor' essentially prior to sending the fuel to get burnt, it would be passed into a hot zone (in front of the burner) wherein the liquid would turn to a vapor, guaranteeing the burn. Would be fun to experiment with wrapping a stainless fuel line around the burner housing you have prior to feeding it to allow the LP to turn.
I personally rate the contents of this channel 10/10.
Accounting the intro and overall goofyness: 11/10!
Be carful getting graphite on the combustion chamber, you'll burn holes on it wherever the graphite contacts. I rebuild turbine engines from helicopters and I've seen guys mark things with a pencil and you can see exactly what they wrote after the engine heats up and anywhere the graphite was there's no longer metal
Interesting, never knew that.
Thanks!
Your videos bring me so much joy. Keep it up.
Amazing as always. Fantastic "Cooking with a Jet" intro
i subscribed 10 seconds before he said "please subscribe"
since finding your channel i have watched almost every single one of them, they are extremely educational and your ability to explain complex principles and problems is astounding. you should do a collaboration video with a channel like smarter every day or Mark Rober or one of your favorite channels, thanks.
Propane fueled recip engines usually have engine coolant heated regulators to maintain stable output pressures and to help vaporization. In future builds that might be worth looking into and/or bleeding off a bit of warm/hot air from somewhere to warm the supply tank. Can't wait to see this coupled to a matching power-take-off turbine. Your grand-finale should be a steam turbine powered by all the waste heat for your very own miniature combined cycle power plant!
Okay, that is an awesome little engine! Holy crap I did not expect that much power output or heat whenyou put the board into the exhaust. 😊✔
With most RC turbines there's no fan infront of the RC centrifugal compressor blades, it's just the motor tied directly to the rotor. When the turbine shuts off, the motor remains on for cooling and it also acts as a flywheel+alternator.
“It’s dangerously loud, I love this thing!”
I love this guy!
I HAD MY HEADPHONES AND MY WIFE SAID "WHAT THE HELL ARE YOU LISTENING TO?"
WHAT A MISTAKE THAT QUESTION WAS... I SPENT THE NEXT 30 MINUTES EXPLAINING IT TO HER!! HA! HA!
SHE DOESN'T ASK ME ANY MORE QUESTIONS!! : )
I noticed that surging issue in the first video, and it reminded me exactly of the same issue with liquid and gas fueled camp stoves; in liquid feed mode at reduced pressures you end up with what seems like pressure resonance creating an inconsistent burn (as you said due to inconsistent vaporization, and presumably resulting backpressure), and in gas feed mode, it runs beautifully. Some stoves get around this by reducing the volume between the valve and the atomizer.
He mentioned that the combustion chamber is small with small turbos which makes it less efficient
Isnt it possible to use the large combustion chamber on the small turbo??
This series completes my life guys!!!!
That chicken look exhausted
For the propane perhaps use a liquid source, or large tank source, and then have an "evaporation chamber" and/or buffer tank.
On tonight’s Tech Ingredients
“cooking in a hurricane”
more importantly the do’s and don’ts of high velocity basting!
Here’s BBQ sauce in your eye! 😂
THE START OF A GREAT ADVERTISING AND MARKETING CAREER FOR YOU MAVOS!!! HA! HA!
Pretty impressive! I would love to see what you do next with both types of jet engine.
If you were my neighbour, you would have trouble with keeping me away from your tests!
Thanks for the work / fun / effort / time / money that you put into providing these videos. 🙂👍
More charts and graphs please. I don't know about the general RUclips audience but I like seeing real data.
Right at the end of the video with the piece of wood at the exhaust nozzle, made the think of roasting the oak for your whisky video. Maybe you're on to something there. ;-) Great video as always!
Hi,
First of all, thanks to you for explaining the basics of turbo jet engine nice demonstration..your channel is the first one i am subscribing...keep going..all the best
Thanks!
I had to chuckle at your little hop while standing in the exhaust. You look like the quintessential kid in a candy shop. I am jealous of your playtoys!
"It's dangerously loud.... It's a beautiful thing"
Quote of the decade!
It'll be very interesting to see the compound version,
higher pressure means more fuel and air fits in a smaller area,
effectively making the combustion chamber much larger.
I'd still rather see a SPRF style combustion chamber,
with concentric layers around the combustion chamber, and a 1000psi water injection system
which would create additional exhaust volume and reduce heat stress on the turbine side.
Also, keep in mind that, all that noise is caused by turbulence, which reduces efficiency.
.
The non linear design of the turbo would make any attempt at reducing noise/turbulence futile.
I wasn't referring to Turbo whine, although that is also a reducible noise,
I was referring to Combustion Turbulence Noise, which is caused by a variety of factors,
and which can be reduced, with a measurable bump in efficiency.
I was just giving him another point to research, which creates better overall understanding.
I wasn't just referring to the 'whine' as you call it but the vibration in the air being compressed by the turbo has cavitation like water does when you spin a propeller too fast compounded by the non linear path of the air creating a turbulent flow then the explosive expansion of the heated air on the combustion chamber then the restriction of the jet nozzle. Making it quieter is daunting to say the least and any progress on that path would ultimately be futile as it would be minuscule in volume change anyway
Basting that chicken behind the jet engine was the funniest damn thing I've seen in a long time! Great job!!
Thank you very much for your incredible videos.
I am learning so much and get a bunch of input for some new projects.
Great, I hope it helps!
coherent presentation of information every time.
You need automatic sauce injection into the exhaust stream!
Just design an afterburner...then pump through the bbq sauce lmao
NOW THAT'S FUNNY.... BUT LETS DO IT!! : )
Main presenter, if you really wanted to use liquid propane, have you considered running your fuel line (metal fuel line obviously) around the flame tube or exhaust in the form of some heat exchanging coils to convert your liquid supply to vapor before being burned? This is what we do in hot air balloon burners. Also, call up some hot air balloon pilots and ask if they have or have a line on some illegal (to fly) propane tanks they want to get rid of. They're 10 gallon propane tanks with liquid and vapor taps. Quite handy.
The source of the tanks is a good suggestion.
The heating of the fuel posses some challenges. It needs to be effective and therefore the lines need to be long enough and be immersed in the hot gasses, but not obstruct flow. If the fuel expands too much the flow resistance can choke the fuel flow.
You make me think how I lived as long as I have with so little limited knowledge.
Seyton,
Get out there and try things you’ll be amazed what you’ll be able to accomplish!! Just by watching your learning more than 99% of our culture!
Thanks, unfortunately that is all I can do is watching!
Seyton, I understand!! If I met you, I would the possibility & a way to do it!!
There is no such thing as perfection and everything is possible!!
Remember only one certainty in life is death & at so at some point in life, we all run out of time!1
Take it vantage of what you have!!
I wish you the best!!!
this is one smart dude. i like how he explains things technically then paraphrases it i laymen terms.
AGREED 1,000,000%!!!!
HE'S ON THE SAME LEVEL AS DR. CHUCK MISSLER (deceased) WHO IS INCREDIBLE ON EXPLAINING THE MYSTERIES OF THE BIBLE!!
I'VE BEEN WATCHING HIS VIDEOS ON RUclips... AND NOW I'M HOOKED ON TECH INGREDIENTS!!!! : )
Why would ANYONE downvote this video? This is absolutely wonderful, I could see this being incredibly useful. Perhaps running off methane from a digester it could be used to supplement a solar/wind source with zero fossil carbon. Not to mention just the fun of putting something like this on a little cart or cycle!
That introduction gave me Top Gear flashbacks
Dude, you deserve so many more subscribers.
Thanks!
Like, subscribe and SHARE and maybe we'll get there.😀
Good to see you stepped up to a big boy! Just happened to complete work on my phase one engine while building up parts for phase 2 (a 7" dual compressor axial design that I'm scratch building) today and wondered if you ever did anything else with your build.
Couldn't agree more with your synopsis on the pitfalls of using an automotive turbo for these, but it does take a lot of manufacturing of precision parts out of the equation.
On the subject of LP/gaseous fuels, the engine testing groups use a fuel warming system that's rather elaborate to get around the cooling issue, though for us backyard guys, a kiddie pool filled with water and a heating element works equally well based on scale of our supply. I had a reptile heating pad from a fermenting project long ago that I used, as it maintains a good 120* F quiet easily, but a resourceful gent such as yourself could easily rig up something with a bit more grunt. You could also go overboard and build an insulated and heated holding chamber, but the kiddie pool is much more practical.
I really liked your approach with the 'injection plate' idea as I came up with something similar for my phase 2 engine, though quite different in deployment as its designed around running hydrogen fuel at a good bit of pressure.
Keep at it as I'm looking forward to seeing your compound operation with a free power turbine take shape one day!
Thanks!
We've gone on to test the engine with both methanol and isopropyl alcohol. It works at least as well as with the propane, requires no warming or propane to start and works well with the plate diffuser too.
Oh, and be careful of parallel turbos. Just like parallel diodes, a small difference in the performance between the two can lead to a runaway seasaaw. Personally, I'd recommend going to series operation and reaping the added benefit of increased effeciency.
@@TechIngredients Ah, very smart with your fuel swap, sir, and thank you for the advice! My larger engine will actually be kind of a hybrid, as an axial arrangement with compound components. I suspect there's a reason the pros don't do this, but for the sake of experimentation and not having to drive 6-7 rows of parasitic compressors, I'm having a go. =)
Add: I did have a brief research period of looking at actual compound turbo setups, and you are right on the money with how those things are sized and oriented. In my build up of parts for the first engine I happened to land some large compressor wheels from what I suspect were APU units, which is why I'm going a different route. Who knows, with a bit of work and a massive stroke of luck, it could be revolutionary (probably not though; it'd be tough to outdo the Williams-era engines!) in small jet engine design.
A lot smoother than before.
And I’ll let you know this is the boyfriend to this lovely lady here! But I want you guys to know through my RUclips channel do the circumstances I don’t have an active nothing wrong other than finances, but I want you guys to know that I really love your education and how detail explanation mathematically etc. that you explain things into is amazing you’re an excellent teacher or a sensei to say the least but you’re an amazing teacher professor thank you very much I really appreciate you!!!
sincerely,
Richard R. Ellis
So cool you guys!! @15:04 Don't ever lose that part of you...
Really want to let you guys know that you really are the best content for me on the platform right now, really as exciting as, Applied Science, Abomb, Applied Science, Cody, Adam Savage, Acorn to Arabella, The thought Emporium, Nile Red, Curious Droid, David Windestal... The list could go on, Truly fascinating content. Please keep it coming.
Special mention to AvE, my chooch was in my chach... scuses
Cooking chicken in the exhaust is a terrible, terrible idea.
Thank you for doing it for us anyway.
Yes, doing it like that the front is going to get burnt while the back is going to be raw! They may be amazing at science but their cooking needs a lot of work, and a rotisserie. /s
Love your videos, I don’t understand half of what you’re talking about but very informative n interesting. Keep up the awesome work n I look forward to your next instalment 👍👍👍👍
I love your videos so much! Always entertaining and educating.
I absolutely love this channel!!! You guys are awesome!
Thanks 🙏 a lot for all information In this video, this is my new project with my students
Great, food luck
Loving your content. Thanks a lot for the knowledge drop.
Sure!
On a more serious note, increasing the exhaust mass as a means of increasing engine thrust (and efficiency) is very clearly seen on the increased bypass ratio on turbofans. They started out low, but they're now as high as 11:1 or even more on the GEnx and Trent 1100 engines, which means that only 1/11th of the mass passing through the engine is used for combustion, and the rest is just propelled out the back by the enormous fan.
That's right. They are approaching the equivalent of ducted turboprops.
