Sounds like Integza might benefit from such a fuel system, but part of the fun of his channel is watching him flail.
I like to call it "struggle pr0n". 😎
Damn them tomatoes!
@@creativecomposites6193 LOL! :D
@@michaelblacktree 🤣🤣🤣
Yeah, watching him bumblefack around is fun for sure.
Some people, like Grant Thompson long long ago, got me interested in diy and engineering. You, you keep me hooked on my engineering major. No matter the bullshit, the little reports to write, the stupid simulations in solidworks, seeing you at work makes me want to be an engineer. Thanks, from the bottom of my heart.
Thank you! Stick it out.
I am a fan and use McMaster Carr but lookout. I found a Clippard valve that have used over the years priced at $179 on McMaster that sells for $29 on the Clippard website. Ejector nozzles $60 on McMaster $19 elsewhere. A 3 inch brass ball valve $479 McMaster, $120 plumbing supply. Low cost valve was domestic manufacturer and excellent quality. Some things seem reasonable some not. I still buy stuff there every week.
Its search function is an epic place to start regardless
McMaster Carr has lower probability of fakes or seconds due to a solid supply chain. Not everything is foolproof. But for dangerous or professional applications, I think we should use professional suppliers. For fun, safe home projects, other suppliers certainly can save money.
I won't say it justifies $179 vs $29, but remember they're a stocking distributor. It does cost money to maintain inventory, from space to warehouse it, to people to stock and pull orders, to paying taxes on unsold inventory, to SKU management. I don't know what the turnover is on any given item, but some are going to sell daily and others might sell once a year. It's this same reason that people get appalled by how much buying a car part from a dealer costs vs when it comes on the car (not talking about things like air filters, but more obscure rarely replaced parts, like dash clusters, ECUs, etc).
Thanks for mentioning McMaster Carr. I buy from them frequently. They have by far the best website, with product descriptions written by people who know what they're describing. Their shipping is remarkable fast too. It's not unusual for me to order (before 3PM) and have the parts the next day. And they DO NOT sell any garbage quality merchandise like that mega site that has a phallic symbol on all their boxes and trucks. 😆
it's hard to justify them when i need twelve strange 80mm thin wall bearings that mcmaster would sell at $70 a pop. but generally they're great.
14:35 AND THERE IS A BILL OF MATERIALS?!? Absolutely Amazing!
I’m not going to build this project but I’m enjoying watching you build it.
I'm so glad to have you as my Science teacher. Thanks for the great videos!
I'm waiting for when he advances to making his first sodium cooled thorium nuclear reactor.
I'd use lithium as it converts neutrons into tritium. Useful stuff in fusion reactors.
@@TechIngredients Also useful in watch faces, marker lamps, and firearm sights!
Whatever has changed with the audio balance in the last couple videos, I think maybe the editor should listen to the audio through multiple sources, IE headphones, and multiples kinds of speakers, because the highs are getting hissy and the mids are a bit drowned out. Love this short videos breaking everything down in a more edible format that doesn't force me to addictively spend an hour that is harder and harder to find time for.
Thank you for the clear, concise information and reference to parts/ hardware used.
You are such a great teacher man!
Thank you for the production.
Perfect intro music !! Straight to the point and memorable
Like your off the shelf components to design with. We don't have to reinvent the wheel for each component that we use...love your channel! Keep up the good work!!
Another great video 👍 wish I had the space and time to tinker like you guy's
It is really cool that you go over how to make these projects at home, even if I don't plan to make this one specifically.
Love your videos and your new schedule. I'm in haven
Even thou I will probably never build a jet engine, I learn something new that explains something else I have see before: why pressure gages have liquid inside, and what liquid it is. Super with bonus. I always learn a lot of new things, with each of your videos :) :)
Thank you for this.
Heck yeah! Thanks Tech Ingredients. Your videos have been super helpful for the Tesla Turbine Jet Engine APUs I’m building!
Great, good luck!
Bravo on the single take! (Watched the stopwatch!)
Have watch you for years and loved your channel. Just joined Patreon cause I want to build a turbojet engine. Keep the specs coming. Would love to see what is in the control box also. Thanks Bob
Thanks!
You made the rum you spoke of right? Your shows are so totally informative. You are a joy to watch. until your next show have a good one!
I loved the distilled spirits videos he made. Too bad I live in California, where beer and wine is all I’m legally allowed to make (and kombucha, too).
Thanks for sharing 👍
In Poland there is a lot of cars adapted to use propane-butane mixture. It is transported in liquid phase close to engine. There is a evaporator there it has 4 ports. Propane liquid inlet, propane gas outlet and inlet/outlet for fluid that moves heat from engine to the radiator. So engine has better cooled and has fuel in preferred gas phase.
i learned even more some rocket science! Love this channel. Thank you.
Well, Turbojet / Jet turbine engine science in this case, but they do rockets as well! I'd love to see them do a similar series on monoprop rocket engines. Going back nearly 15 years ago, I used to tinker with fairly simple H2O2 monoprop and Kerosene/NOS bi-prop engines. It's a fun hobby but pretty dangerous, especially when dealing with HTP (highly concentrated Peroxide, like 90%+).
@@racerex340 yes!!! 100% i think we're accidently learning rockets science. Not long ago on the channel we were treated to a full in-depth series of video on the optimum hobby firework fuel. which was awesome. also as a side note, the most concentrated 'usable' hydrogen peroxide fuel will never be above 70% (for long time). it both decays and same time is hygroscopic advancing the decay
@@Palmit_Rob, I used to buy 50% Food grade and distill to over 90% using vacuum distillation. Yes, it does decompose fairly quickly, but with the right container, you can keep 90%+ for a few weeks airtight. A cap full spilled would easily catch a lawn on fire... My monoprop engines just used simple silver screen packs as the catalyst, which would poison after a few runs but could be cleaned up by heating them cherry hot, quench in water and then run them through an isopropyl ultrasonic bath. You could make the packs last longer by weaving in platinum screen every 6 or 7 screens but that was far too expensive for what was basically me playing around.
@@racerex340 i believe you and i are agreeing :) 90%, to my small braincell, is quite a good yield, but hard to store usably for a good length of time (years would be ideal). even with special equipment. I reckon tech ingredients will slowly advance us to methane ch4, but first we will learn superchill. :)
@@Palmit_ if I had access to a really good lathe, I'd probably do HTP + nitrous oxide. Those high density rubber hybrids have great reliability, simple and can be throttled and stopped / restarted.
Great video!
I want to build a turbo jet, I've built a couple hundred pulse jets. But now I've gathered up everything needed for a turbo jet project, so this is a great video for me, sounds fun' good job on this & all your other videos " thx for the good information" I love it"
Excellent video. I really appreciate this series and just purchased turbocharger myself to do this project. I hope you will touch on the ignition system in your upcoming video as well. My intuition is that the igniter type and placement is not trivial. Thanks guys!
It isn't and we will.
Cool. Haven’t seen you guys in a while.
Up here in Canada McMaster Carr is expensive and has expensive shipping. I bought a 2" steel brush and by the time it was shipped it was $80. Still, the selection is fantastic.
As a kid whose father was never there and his mother was abusive I watch your videos and cry that I never got to do anything like this with my parents And I find myself feeling very guilty that I have never done anything enjoyable like this with my own daughter.... The resources that you have are one thing but the knowledge emotion and time you're spending with your child is heroism... You sir are the perfect parent
Thanks! It's never too late...
Thank you
I'm not sure if this is a silly question but seems as you said that more pressure will result in better atomisation - Would taking a diesel direct-port fuel injection system (With one of the newer electrically driven pump) from a vehicle be better for this application? You'd have a very high pressure, an injector designed to atomise the liquid fuel well with extremely consistent repeatability and you can drive the injector using a PWM signal to adjust the fuel flow. I'm not sure if a direct-port fuel injector would handle the temperature of a jet engine, but they are designed to poke into the cylinder of an engine.
It might.
Or maybe a simple gasoline car High Pressure Fuel Pump? At lease some of those run off the camshaft so are not electric.
Those injector spray when there is a pulse, and the volume of fuel depends on the pressure. What modern common rail diesel do, it to trigger multiple times per cycle, and vary the pressure in the rail to deliver the right amount at the right time, so it runs as efficient as possible with "little bad stuff". A PWM signal is not what you need, it is the frequency. Also note that the coils based injectors (old) require quite a good current pulse, and the more modern piezo ones require a a good voltage kick (100~200V) so the drivers need to be pretty on point too.
McMasterCarr is my addiction. I’m a biologist doing automation of cell therapy/gene therapy assays. I have always been extremely handy so it wasn’t a big step to basically become an de facto engineer. All science is art. Leonardo, you know. Appreciate your approach a lot. Btw. Ordered some heat transfer compound on your website for my Biotec and never got it. Any path forward you’d recommend? Edit: Actually, you might appreciate this: I’d like to use your compound with a “dry bath” from Thory Pines Scientific. (Not sure I spelled this right) It cools down to -20C, theoretically. I get -12 in my application. That’s why I need your compound. Their device is very unique. Check it out.
I also ordered some of the thermal paste. Not sure what's happening but it's been months for me and I've sent them emails to no avail. Maybe they need enough orders to make a batch.
@@zmonchamp Good to know, thanks. Very disappointing though. Would at least expect some communication.
@@HansWeberHimself it's really disappointing considering not that long ago they did a video about being ethical, and not to believe in the scam products. I thought maybe they'd see this and we'd both get answers.
@@zmonchamp I’d appreciate answers a lot.
GREAT VIDEO, thanks you make some cool stuff!!!!!!!!!! mike
Tremendous variety of very interesting subjects investigated, presented a explained clearly. thank you!! Ground-effect (increased air pressure) hydrofoil catamaran or trimaran a possibility? With your analysis and crestivury, hopefylly yes. With easily accessible highly accurate weather temperature, wave, and wind prediction, one could pick suitable weather windows to skim over the waves to a destination. For a d-i-y budget, far, far, far, less than the rich-man's toy 7figure ground effect plane I've seen that looks like it has bat wings, and may not incorporate hyrofoils as fully as it could.
Here's how to try this at home, says the zany rocket guy. Love it.
I have no interest in jet engines or building jet engines other than perhaps a curiosity as to why the M1A1 Abrams tank uses a jet engine instead of piston. However I think this presenter could talk about any subject and for some reason which I have not quite put my finger on everything he says is fascinating! Perhaps it's the depth of knowledge he brings to the table, or for the additional things I learn when watching these Tech Ingredients videos!
If I remember correctly it was due to High Power Density, Less Maintenance/Things to Go Wrong, and that they aren’t too picky fuel wise. I’m not an expert in the area though so feel free to chime in if you know more/have corrections or something.
@@ericlotze7724 Wow! I only knew part of that! I heard from a guy that used to drive tanks that they give them specs and settings to run every type of fuel and a few things that we wouldn't even consider fuel in those tank turbines! Thank you!
Whatcha been up to Bob ? Oh, nothing much just tinkering around on my Jet Engine build.
This strapped to a go-kart? Yes please.
Another nice presentation ,...... with your gauges , on a new build its advisable not to use fluid filled ones as they can mask "problems" , an "empty" gauge will bounce around and alert the builder to a potential problem , things like a cavitating fuel pump, compressor surging or pulsing combustion, fluid filled gauges best used once the engine is sorted
Good point.
I've been using McMaster-Carr for at least 50 years but recently a lot of my purchases have been going to the ever-growing offering of very cost-effective parts from Automation Direct.
Fair enough. When we lived in Chicago, the local McMaster-Carr distributor had a UPS hub WITHIN their warehouse. Orders made by noon were delivered that same day!
I remember my buddy breaking the seal on a paintball CO2 tank and it instantly froze his fingers to it. Not sure if that's the same thing with propane, but it was an event I remember from 20 years ago.
It is. Propane can be used to freeze off warts and is a component in over the counter remedies.
And if freezing them off doesn't work, then you can burn them off :)
Do I see fireflies in the backyard? So neat. I didn't get to see any this summer
The air duster is basically r134a. Opd tanks will flow liquid upside down I refill 16oz tanks they just won’t flow gas or liquid if you don’t have a anything hooked up
Fairly early. Love this channel.
Use the heat from the bearing cooler and oil cooler to heat a water jacket on the propane tank.
Look up jet powered garbage trucks. Very interesting ted talk that works through a lot of the issues mentioned here.
You must live in the woods, around here I would have the cops at my house day and night , every day and night. but what fun
As a gas engineer this is called the 'vapour take off rate' standing in warm water does not help. Adding tank volume eg a larger tank or tanks in series would help but it also adds the issue of greater weight of tanks. Liquid fuel is best LPG for a very small engine - maybe ok.
Pulsatile - my new word for the day.
Im interested do you have a schematics? Maybe not too detailed. Like when i open old lamp tune radio schematics, so it would easier to understand this circular pump fuel flow. Thank you
I know it's childish and dumb, but I really want to see this run until total destruction. I have gotten bit by the bee and have looked at a lot of these jets lately. Some of them are so simple and crude it's as hilarious as it is wonderful. None of them have been anywhere near as professionally researched and executed as this though. I, like most, have absolutely no intention of building one myself, but I love to learn every tiny detail involved in this. The research and fabrication seen on this channel is really unparalleled. Thanks for all the content! And oh my world I want to see someone slap a jet like this on a go-kart.
THE JUICE!!!!!
To get Propane from liquid to gas phase you could use an expanding valve and a radiator of a car air conditioning
You could
In the aviation industry, we call that column that smoothes out pulses…….an accumulator 😉
In plumbing, we do the same thing with a hammer arrestor!
After draining the fuel from the vertical tube how do you re-introduce the column of air back into the stand pipe and how much air?
Once any trapped fuel is drained, the top valve is closed and the air is then unable to leave the next time fuel is driven into the manifold below.
@@TechIngredients Got it! 👍I'm working on getting the parts together for this build. I have to say, the details in your videos is what gives me the courage to go forth in building rather than just being another video I watch for fun. Always grateful for your guidance🙏
Suck, squeeze, push, bang, boom … a way to think of the stages of a jet engine. Suck - Fan, the blades at the front that draw the air in. Squeeze - compressor stage that increases the air pressure. Push - the initial portion of the combustion chamber that brings in the air. Bang - the combustion chamber where the fuel and air ignite. Boom - the exhaust turbine / afterburner. Of course there are a number of ancillary pieces to modern jet engines.
Accumulator is the term for the cylinder
Can you make a secondary video showing how to use lpg and liquid fuel(ie diesel) injector?
You might find our video on mixing nitrous and rockets useful.
"pulsations" is the word I think you're looking for
Pulsatile is an adjective.
How about pulsatism 🤔🙄
Power!!!!!!
Please make high-resolution inertial propulsion 🙏🏻
Would a slowly semi-opening-and-closing valve along with the pump create an increased pressure flow?
No.
Propane cans with heavy frost : Ive seen roofers turn their big torches on the tank at intervals to smooth out the flow-unnerving to be close to...
Old k jet parts pump running a 5.8 bar , injector is a kontinuous output that makes a spray pattern that can vary the old fuel distribution system could be used for the throttle, and have four five six or eight injectors . You could run gasoline to diesel, any j type jet fuel, alcohol etc. Mercedes ran two in series to make just under 100 psi for the last three years of the ke jetronic
"I've run this kind of engine on kerosene and had no problems, it's always worked." I should hope so, considering that Jet Fuel is Kerosene... (at varying degrees of refinement...)
10:10 Is there any Combustion/Explosion Risk? Granted if you aren’t using volatile fuels I’d imagine the risk is lower, but does an inert gas need to be used? (Edit: Fixed the Timecode)
The likelihood is very low, but yes there certainly is an explosion risk. That’s why all accumulators are charged with nitrogen or other inert gases. It would be as simple as putting a schrader valve on top of the metal pipe and filling it with nitrogen.
What size fuel nozzle do you use?
I’ll file this in my, saw this done a decade ago.
I'm now hoping to see a rocket-powered go-kart at the end of this series. 🙏🙂😬
Working on it.🙂
You seen this 3KW turbine gen set?
how about that pulse jet that you made?
"technological ingredients" are what goes into it 😄
Do to the global warming potential of the current refrigerant used in modern air conditioners they are going to start phasing it out. It’s replacement is propane based because a lot of energy required for phase change.
One would think "it's a propane bottle" NNOOO there is an assortment of gas bottles used for different applications! As a scientist I never gave this a thought WOWZZA Thanks
I love this video, knowledge is key to science!
Howard, do you have another AC for me to buy?
Now how can I incorporate this into a PC liquid cooling system? :D
you said one of the drawbacks of afterburners is their low compression. Which immediately made me think of compressing the air before burning it in the afterburner, maybe with another compressor wheel... Today it clicked, it's exactly the compoud turbo system you are talking about, right?
That's right. Afterburners should always be an "afterthought". The secret is compression ratio and you need multiple stages for that.
Not necessarily , if the gas producer iand afterburner are constructed correctly and the required turbine temps are used , we can achieved a choked afterburner nozzle , unfortunately this guy doesn't really know what he's talking about , he sprouts the words but not the experience
1:51 "goose the throttle" is that a technical term? lol
You could always use a liquid propane tank with a fuel pump. PM me if you would like more information we design fuel systems that utilize these tanks for liquid propane injection fuel systems for vehicles.
Have you tried an impinging injector for better atomization?
Yes, we tried that in the hybrid rocket engines and the metal posts frequently melted. I'd be afraid of damaging the turbine.
I've heard you can buy Jet A at Pease. I'd considered it when I had trouble finding kerosene for a heater, but even diesel seems like a better option. For an actual jet engine, what could be better?
Kerosene has about half the viscosity of diesel and so it will atomize easier.
@@TechIngredients Well… glad I was able to find Kerosene!
What's wrong with making a copper coil as a heat exchanger in some water to expand the fuel into gaseous phase? You'd have the tank upside down as you have there, but then expand it externally in the coil in a big bucket of water. Did you find that you couldn't get it to expand evenly and you'd get liquid propane sputtering into the combustion chamber?
It's unnecessarily complex and bulky when fuels like kerosene work well.
Great video thank you for making it. Think you could try to build the microwave / plasma based jet engine?
How would something more viscous like Heavy Fuel Oil (Fossil Fuel) or Pyrolysis Oil (From Biomass, also called “Bio-Oil” or “Bio-Crude” in papers, although the latter refers to Hydrothermal Liquidation crude more often) work? Wondering as Pyrolysis Oil is kinda nasty stuff but i hear gas turbines can burn all sorts of stuff!
Especially with the Turboshaft version connected to a generator (and maybe even a Heat Recovery Steam Generator!) you could convert waste engine oil/pyrolysis oil into not just heat, like a waste oil burner, but electricity!
Jeez how did Jet Man get all his gear into one tiny backpack?
The Jet Engines that “Gravity Industries” or LLC or whatever the name is are Commercial Off The Shelf Jet Engines (sold as RC Jet Engines, I don’t know if they sell them as micro-jet engines or something too; some gliders use them for self-towing, etc) that basically just need a fuel line and electric control (similar to that for the BLDC motors in RC Quadcopters etc). I would bet the ones they use too have electric starter motors. So since they are custom built for small Size+Weight etc instead of made using Turbocharger Turbines designed for Cars’ Exhaust, they can optimize for size and plug-and-play operation. Hope this helps, and i am not an engineer or anything so anyone else feel free to chime in!
Still damn impressive though, and idk how i would feel about running fuel lines down my arms with flaming jets inches away!
I have a particularly noisy neighbour and he has a massive sound system. Now I have tried everything "within financial restrictions" to stop the noise. But the sound is so loud my walls vibrate. Our police isn't helpful and talking to them doesn't help. So I am thinking EMP? Or can I make his music unpleasant by injecting a frequency in some way. If you have time and some ideas it would be really helpful.
Use technology to measure and record the volume levels as well as the time this occurs during the day. Get unimpeachable documentation, witnesses and a record of your interaction then go to the police and lay this out. If you're position is justified, they're more likely to help when you seem reasonable and organized. Escalating will do the opposite and you risk the police acting in your neighbor's defense.
how much did your build cost? I've been wanting to do this for a long time, but Money is a problem. LOL
As it stands, a couple of thousand dollars. You could do it for about half that.
I wonder how well a direct injection fuel injector from an automobile would work? You might have to find a deal on the high-pressure fuel pump, because they tend to be pricey.
The injector from a pistons ICE will not work. They need pressure pulses that trigger the injection. If it is electronic, the electric pulses trigger, but it is basically a fuel volume per pulse, depends on pressure. If it is mechanic, you need the pump to create the pulses, even more complicated and still pulsed.
Hmm, two of those turbo-jet engines mounted on the catamaran you built for the Tesla powerpack . . . .
What restrictive valve?... Good Movie DR
What is this engine going to be powering?
Not sure yet. This is a small engine and with more power in a compound configuration or with rotary output with a turboshaft, there are more options.
Hot air balloonists have been known to "spike" their liquid takeoff tanks with Nitrogen, particularly in cold weather but you really need to know what you're doing. I have a dual liquid/vapour take off tank which was retired from ballooning.
Still waiting for the compound turbo jet engine....
That will be a while yet.
@@TechIngredients Aww. 😓
My jet runs on beans.
Ya pressurized fuel of any type can be scary on a mobile application if things don't go as planned. I just finished designing the fuel tanks for my J34 powered 6000hp jet engine pontoon I'll be building this week. It requires 10gal/min @ 100psi. I finally found a brushless variable speed NHRA top fuel dragster pump that will be up to the task. Just really expensive! Please subscribe... hahaha... Love your videos!
Probably for the safety of the bbq'er 😂😂😂
I wonder if you could build something like this but with a tesla turbine and with the turbocharger compressor part. No fuel would be needed, just compressed air
That's similar to our future plans.
